Obama, Congress Waving Bye-Bye Lower Taxes?

The first family arrived in the president's idyllic home state of Hawaii early today to celebrate the holidays, but President Obama, who along with Michelle will pay tribute Sunday to the late Sen. Daniel Inouye at the National Memorial Cemetery of the Pacific, could be returning home to Washington sooner than he expected.

That's because the President didn't get his Christmas wish: a deal with Congress on the looming fiscal cliff.

Members of Congress streamed out of the Capitol Friday night with no agreement to avert the fiscal cliff -- a massive package of mandatory tax increases and federal spending cuts triggered if no deal is worked out to cut the deficit. Congress is expected to be back in session by Thursday.

It's unclear when President Obama may return from Hawaii. His limited vacation time will not be without updates on continuing talks. Staff members for both sides are expected to exchange emails and phone calls over the next couple of days.

Meanwhile, Speaker of the House John Boehner is home in Ohio. He recorded the weekly GOP address before leaving Washington, stressing the president's role in the failure to reach an agreement on the cliff.

"What the president has offered so far simply won't do anything to solve our spending problem and begin to address our nation's crippling debt," he said in the recorded address, "The House has done its part to avert this entire fiscal cliff. ... The events of the past week make it clearer than ever that these measures reflect the will of the House."

Senate Minority Leader Mitch McConnell echoed the sentiment while lamenting the failure to reach a compromise.

"I'm stuck here in Washington trying to prevent my fellow Kentuckians having to shell out more money to Uncle Sam next year," he said.

McConnell is also traveling to Hawaii to attend the Inouye service Sunday.

If the White House and Congress cannot reach a deficit-cutting budget agreement by year's end, by law the across-the-board tax hikes and spending cuts -- the so called fiscal cliff -- will go into effect. Many economists say that will likely send the economy into a new recession.

Reports today shed light on how negotiations fell apart behind closed doors. The Wall Street Journal, citing unnamed sources, reported that when Boehner expressed his opposition to tax rate increases, the president allegedly responded, "You are asking me to accept Mitt Romney's tax plan. Why would I do that?"

The icy exchange continued when, in reference to Boehner's offer to secure $800 billion in revenue by limiting deductions, the speaker reportedly implored the president, "What do I get?"

The president's alleged response: "You get nothing. I get that for free."

The account is perhaps the most thorough and hostile released about the series of unsuccessful talks Obama and Boehner have had in an effort to reach an agreement about the cliff.

Unable to agree to a "big deal" on taxes and entitlements, the president is now reportedly hoping to reach a "small deal" with Republicans to avoid the fiscal cliff.

Such a deal would extend unemployment benefits and set the tone for a bigger deal with Republicans down the line.

In his own weekly address, Obama called this smaller deal "an achievable goal ... that can get done in 10 days."

But though there is no definitive way to say one way or the other whether it really is an achievable goal, one thing is for certain: Republican leadership does not agree with the president on this question.

Of reaching an agreement on the fiscal cliff by the deadline, Boehner said, "How we get there, God only knows."

Tax fight sends GOP into chaos

The main thing that has held Republicans together philosophically is the belief in holding down taxes. Not one of them in Congress has voted for a significant increase in more than two decades.

Now that very issue is tearing the GOP apart and making it an all-but-ungovernable majority for Speaker John A. Boehner (R-Ohio) to lead in the House.

Disarray is a word much overused in politics. But it barely begins to describe the current state of chaos and incoherence as Republicans come to terms with electoral defeat and try to regroup against a year-end deadline to avert a fiscal crisis.

The presidential election was fought in large measure over the question of whether some Americans should pay more in taxes. Republicans lost that argument with the voters, who polls show are strongly in favor of raising rates for the wealthy.

But a sizable contingent within the GOP doesn’t see it that way and is unwilling to declare defeat on a tenet that so defines them. Nor are they prepared to settle for getting the best deal they can, as a means of avoiding the tax hikes on virtually everyone else that would take effect if no deal is reached.

When Boehner tried to bend even a little, by proposing to raise rates on income over $1 million, his party humiliated him, forcing him Thursday night to abruptly cancel a vote on his “Plan B.”

“We had a number of our members who just really didn’t want to be perceived as having raised taxes,” Boehner said Friday. “That was the real issue.”

Whether and how the party can resolve the issue has implications going forward. It could determine Boehner’s viability — even his survival— as leader of the only part of the federal government controlled by the Republicans.

It also could set the terms of engagement for the battles that lie ahead, including such contentious ones as immigration and the fiscal 2013 spending bills, which are funded for only half the year and which expire March 31.

As things stand now, some worry that nothing short of a catastrophe could force a resolution.

“We have sunk to the lowest common denominator in order to get a deal — sheer panic,” said Republican strategist Ron Bonjean, a former aide to House and Senate leadership. “The reality of a stock market crash is probably the only way Washington will strike a deal. It is probably the only scenario that could likely force the speaker’s hand and allow for a deal driven by Democratic votes to pass the House.”

Which, of course, is not an ideal way to govern.

“The hard-core anti-tax conservatives in the GOP seem to believe that Barack Obama will be blamed if there is no agreement reached to avoid sequestration and the tax increases that are coming,” said Sheldon D. Pollack, a University of Delaware law and political science professor who has written a history of Republican anti-tax policy. “Calculated gamble? Or are they simply incapable of recognizing that they do not control the White House or the Senate, and hence do not have the ability to control the agenda? Sadly, I think it is the latter.”

Their intransigence alone is unlikely to sell the electorate on the Republican point of view on taxes.

“You have to make an argument. You have to go out there and engage. You can’t just simply assert a position,” said GOP pollster David Winston, who advises the House leadership. “Part of the dynamic for Boehner is that he’s trying to have the debate over economic policies that should have occurred during the election, and he also has to deal with this piece of legislation.”

As long as there has been a Republican Party, there has been at least a faction within it that has taken a hard-line stance on taxes, Pollack said. But it has not always had the upper hand.

Abraham Lincoln, the first Republican president, was also the first to put a national income tax into place, as a temporary means of funding the Civil War. Even then, House Ways and Means Chairman Thaddeus Stevens (now enjoying a return to popular consciousness as Tommy Lee Jones’s character in the movie “Lincoln”) denounced the idea of a graduated rate structure as a “strange way to punish men because they are rich.”

The 16th Amendment, which established the constitutionality of the federal income tax in 1913, was proposed by a Republican, Senate Finance Committee Chairman Nelson W. Aldrich. But it was decried by another one, Sen. Henry Cabot Lodge of Massachusetts, as “confiscation of property under the guise of taxation” and “a pillage of a class.”

The divisions went on until the 1980 election of Ronald Reagan, who ran as an advocate of tax-cutting supply-side economics.

In 1990, Newt Gingrich established himself as the de facto head of his party in the House, when he stood up to a president of his own party and led the opposition to George H.W. Bush’s tax increases.

Gingrich insisted in an interview Friday that the Republicans still have leverage, if they are willing to fight hard enough.

“They need a strategy, not just a way of getting through this week,” he said.

Squash: World No. 1 Nicol David extends haul of World Open titles

GRAND CAYMAN, Cayman Islands: Nicol David extended her record of World Open titles to seven from eight finals on Friday with a balanced performance and great patience to beat English third seed Laura Massaro.

The Malaysian heroine's 11-6 11-8 11-6 victory silenced critics who had suggested younger rivals were closing the gap on the 29-year-old champion.

Massaro forced many long rallies and even led 7-5 in the second game, but David responded well to the important moments which followed.

She mixed containment with well-timed drops and lightning-quick changes of direction that prevented her opponent from getting a crucial foothold in the match.

The outcome was that David only dropped one game throughout the entire tournament, but she had to focus harder and for longer in the final than in any of her four other encounters.

Her relief and joy at surviving the perpetual pressure of expectations yet again was smilingly obvious.

She held her head in both hands, then placed her hands high on the court, and finally caressed the ball affectionately against a wall before allowing herself to accept that no more was required of her racket.

Then her words reflected the frequent struggle between doubt and self-confidence.

"I can't believe it," she said. "I just can't believe it.

"I am just so pleased with my match. Laura pushed me every point. There was no point where I could let up because she was just on it every point. She played a very good match."

David knew the danger well as Massaro is one of the few players to have beaten her twice. However, she did so last year and, although the challenger has improved further since then, the champion at her best has too, perhaps just as much.

Two of the most crucial moments came when David got back to 7-7 in the pivotal middle game and then nosed ahead to 8-7 with a disputed point.

The levelling rally saw brilliantly nimble retrieves from David, plus some patient backhand wall straight driving with a tight little backhand drop to finish it.

That was followed in the next rally by a marginally mistimed backhand drive by Massaro, which caused the ball to come away from the wall and resulted in her slightly impeding David.

A penalty stroke was awarded, Massaro's video review appeal failing to get the decision overturned.

David pushed hard to capitalise, offered a rare fist pump when she broke through to a two-game lead, and was quickly five points up in the third and motoring away.

"I am a little bit disappointed with that," said Massaro, who had saved a match point in a long and hard semi-final with Raneem El Weleily, the second-seeded Egyptian, and may have paid a price in the third game of the final.

"It was just a few points here and there and that's all the difference," she said. "The middle of the games were so crucial and that's what I have to work on.

"It's still pretty rare that she is beaten. We are still training hard and improving and she's rising to the challenge."

To do that well as she moves through her 30th year, David may need to select peaks more carefully for the tournaments she really wants to win.

But at her best, she is still too fine an athlete and too steady a rallyer for everyone, even during her moments of doubt. Her high profile among the all-time greats is likely to rise yet further.

HC vacates stay on results for 14,000 new PGT posts

CHANDIGARH: While vacating the stay on the announcement of results for around 14,000 new posts of Post Graduate Teachers (PGTs), the Punjab and Haryana high court on Friday held that only those who clear the Haryana Teachers Eligibility Test (HTET) would be eligible for teaching posts in Haryana.

With these orders, candidates having qualified the eligibility test of state, other than Haryana or Central Teachers Eligibility Test (CTET), will not be eligible for these teaching posts in the state.

A division bench headed by chief justice A K Sikri also upheld the condition of Haryana School Teachers Selection Board (HSTSB) that all candidates with four years of teaching experience are eligible for appointments if they qualify HTET before 2015.

The bench passed these orders while dismissing a petition filed by some HTET qualified candidates, who had sought directions to quash the selection criteria which allowed candidates, who have not qualified HTET but are working in any recognized school for the last four years, to become eligible for these posts.

In June this year, Haryana had advertised around 14,000 posts of PGTs in which the government had given relaxation to those candidates from qualifying HTET having teaching experience of four years.

The petitioners had contended that the government was exempting the candidates from HTET just to accommodate the guest teachers working in various schools of the state for last so many years.

Acting on their petition, the HC had restrained HSTSB from declaring the final result of selection in August this year.

Pictures: Fungi Get Into the Holiday Spirit

Photograph courtesy Stephanie Mounaud, J. Craig Venter Institute

Mounaud combined different fungi to create a Santa hat and spell out a holiday message.

Different fungal grow at different rates, so Mounaud's artwork rarely lasts for long. There's only a short window of time when they actually look like what they're suppose to.

"You do have to keep that in perspective when you're making these creations," she said.

For example, the A. flavus fungi that she used to write this message from Santa grows very quickly. "The next day, after looking at this plate, it didn't say 'Ho Ho Ho.' It said 'blah blah blah,'" Mounaud said.

The message also eventually turned green, which was the color she was initially after. "It was a really nice green, which is what I was hoping for. But yellow will do," she said.

The hat was particularly challenging. The fungus used to create it "was troubling because at different temperatures it grows differently. The pigment in this one forms at room temperature but this type of growth needed higher temperatures," Mounaud said.

Not all fungus will grow nicely together. For example, in the hat, "N. fischeri [the brim and ball] did not want to play nice with the P. marneffei [red part of hat] ... so they remained slightly separated."

Obama Still an 'Optimist' on Cliff Deal

Mandel Ngan/AFP/Getty Images

WASHINGTON D.C. – Ten days remain before the mandatory spending cuts and tax increases known as the “fiscal cliff” take effect, but President Obama said he is still a “hopeless optimist” that a federal budget deal can be reached before the year-end deadline that economists agree might plunge the country back into recession.

“Even though Democrats and Republicans are arguing about whether those rates should go up for the wealthiest individuals, all of us – every single one of us -agrees that tax rates shouldn’t go up for the other 98 percent of Americans, which includes 97 percent of small businesses,” he said.

He added that there was “no reason” not to move forward on that aspect, and that it was “within our capacity” to resolve.

The question of whether to raise taxes on incomes over $250,000 remains at an impasse, but is only one element of nuanced legislative wrangling that has left the parties at odds.

For ABC News’ breakdown of the rhetoric versus the reality, click here.

At the White House news conference this evening, the president confirmed he had spoken today to Senate Majority Leader Harry Reid, D-Nev., and House Speaker John Boehner, R-Ohio, although no details of the conversations were disclosed.

The talks came the same day Speaker Boehner admitted “God only knows” the solution to the gridlock, and a day after mounting pressure from within his own Republican Party forced him to pull his alternative proposal from a prospective House vote. That proposal, ”Plan B,” called for extending current tax rates for Americans making up to $1 million a year, a far wealthier threshold than Democrats have advocated.

Boehner acknowledged that even the conservative-leaning “Plan B” did not have the support necessary to pass in the Republican-dominated House, leaving a resolution to the fiscal cliff in doubt.

“In the next few days, I’ve asked leaders of Congress to work towards a package that prevents a tax hike on middle-class Americans, protects unemployment insurance for 2 million Americans, and lays the groundwork for further work on both growth and deficit reduction,” Obama said. ”That’s an achievable goal.  That can get done in 10 days.”

Complicating matters: The halls of Congress are silent tonight. The House of Representatives began its holiday recess Thursday and Senate followed this evening.

Meanwhile, the president has his own vacation to contend with. Tonight, he was embarking for Hawaii and what is typically several weeks of Christmas vacation.

However, during the press conference the president said he would see his congressional colleagues “next week” to continue negotiations, leaving uncertain how long Obama plans to remain in the Aloha State.

The president said he hoped the time off would give leaders “some perspective.”

“Everybody can cool off; everybody can drink some eggnog, have some Christmas cookies, sing some Christmas carols, enjoy the company of loved ones,” he said. “And then I’d ask every member of Congress, while they’re back home, to think about that.  Think about the obligations we have to the people who sent us here.

“This is not simply a contest between parties in terms of who looks good and who doesn’t,” he added later. “There are real-world consequences to what we do here.”

Obama concluded by reiterating that neither side could walk away with “100 percent” of its demands, and that it negotiations couldn’t remain “a contest between parties in terms of who looks good and who doesn’t.”

Boehner’s office reacted quickly to the remarks, continuing recent Republican statements that presidential leadership was at fault for the ongoing gridlock.

“Though the president has failed to offer any solution that passes the test of balance, we remain hopeful he is finally ready to get serious about averting the fiscal cliff,” Boehner said. “The House has already acted to stop all of the looming tax hikes and replace the automatic defense cuts. It is time for the Democratic-run Senate to act, and that is what the speaker told the president tonight.”

The speaker’s office said Boehner “will return to Washington following the holiday, ready to find a solution that can pass both houses of Congress.”

How Boehner’s Plan B for the ‘fiscal cliff’ began and fell apart

John A. Boehner’s week on the brink ended in a painfully familiar place.

It began last week when President Obama delivered a stern message to the House speaker: If there was going to be a deal to tame the nation’s debt, it had to happen now. If they went over the “fiscal cliff,” it would only become harder to reach a deal, Obama said.

The next day, Friday, Boehner (R-Ohio) phoned Obama offering what seemed like a major breakthrough: Republicans would agree to raise tax rates for the first time in decades if the president gave a key concession on entitlement reform.

That offer set in motion seven days of deal making, posturing and cajoling by Boehner and other House leaders, first on a grand deal with the White House and then on a Plan B with their own House caucus. By Thursday night, both deals had fallen apart.

The failure of a grand bargain was the latest oh-so-close moment for Obama and Boehner, who have been dancing around a deal to cut the deficit for the better part of the past two years. And the collapse of Plan B set a new low in Boehner’s sometimes rocky relationship with a House Republican caucus that has long been uneasy about the speaker’s deal making with Obama.

Following the latest breakdown in negotiations, Democrats said Boehner should return to the bargaining table with Obama — or just let House Democrats and 25 or so Republicans vote for a Senate-approved plan to extend tax cuts for the middle class. But Republicans said the well has been so poisoned that restarting bipartisan talks would be more difficult than ever.

In a statement late Thursday, Boehner said it was now up to Senate Majority Leader Harry M. Reid (D-Nev.) and Obama to come up with an agreement — without explaining what role he would play. The speaker ignored reporters’ questions and, at 8:04 p.m., he walked out of the Capitol.

A week earlier, the possibility of a deal seemed as promising as it ever had.

As he was heading home to Ohio for the weekend, Boehner called Obama with an offer to allow tax rates for incomes above $1 million to rise from 35 percent to 39.6 percent. In exchange, Boehner demanded a key change to entitlement spending that would lead to reduced benefits.

With a potential $1 trillion in spending cuts, Boehner also suggested that the debt ceiling could be lifted a similar amount and give the Treasury another year of borrowing authority.

The next 72 hours would prove critical. Having offered so much, Boehner hoped he could keep the details quiet long enough for him to get Obama to agree to enough spending cuts to satisfy his caucus — and so that his leadership team could make the case for compromise in person.

But the details did not stay secret for long. Reports leaked out Saturday evening that Boehner had agreed to raise taxes on millionaires. That was followed by a more alarming leak Sunday evening that Boehner was also willing to grant Obama another increase in the federal debt limit. Home in their districts, unsuspecting rank-and-file Republicans were stunned.

Ex-Beatle's widow lauds Ravi Shankar at US memorial

ENCINITAS, California: Former Beatle George Harrison's widow Olivia joined hundreds of fans and family of Ravi Shankar on Thursday at an open-air memorial to the Indian sitar legend near his California home.

Anoushka Shankar, daughter of the late musician who died last week near San Diego, and her step-sister Grammy-winning singer Norah Jones also paid their last respects at the service in a palm tree-lined meditation centre.

Tributes were read out from fellow musicians and artists who had been inspired by Shankar, labelled "The Godfather of World Music" by the Beatles and compared to Mozart by violin maestro Yehudi Menuhin.

Harrison, whose late husband learned sitar from Shankar and collaborated with him notably on the ground-breaking Concert for Bangladesh in 1971, said the former Beatle had learned so much from their friendship.

"They were like father and son as well as brothers... they made each other laugh as if they shared a secret. And I'm sure they did," said the 64-year-old, whose husband died of cancer in 2001.

Shankar "laid the stepping stones from West to East, that led George to new concepts, alternative philosophies and completely transformed his musical sensibilities," she said.

"They exchanged ideas and melodies until their minds and hearts, East and West, were entwined, like a double helix," she added in Encinitas, where Shankar had a home.

Shankar's 31-year-old daughter Anoushka -- also a sitar player, and just nominated for a Grammy -- told the audience that her father would have approved of the memorial's venue, the Self-Realization Fellowship spiritual centre.

"My father loved spending time here so much, so it feels so right for us to be here celebrating his journey," she said, before tributes were read out from singer Peter Gabriel and film director Martin Scorsese.

Gabriel said: "Ravi Shankar opened the door to non-Western music for millions of people around the world."

"His music has such power, seeming ancient and immediate, impassioned and meditative, full of sorrow and joy. He was a true master," said Scorsese, "From the first time I met him ... his brilliant sitar playing has mesmerised me."

Shankar died last Tuesday at the age of 92, after failing to recover from surgery at a hospital in La Jolla, near San Diego. His family was at his bedside.

Private memorial services were announced both in the United States and India, where Shankar also had a home.

Jazzy soul singer Jones, Shankar's daughter from an affair with a US concert producer, was dressed in black and kept a low profile at Thursday's event in Encinitas, up the coast from San Diego.

His widow Sukanya was also at the California memorial, which started with prayers chanted by M.N. Nandakumara of the Bharatiya Vidya Bhavan institute for Indian art and culture in London.

Nandakumara said that Shankar's music "brought people of various countries, communities together to his soul-stirring music, which was matchless.

"I do not know another musician who has understood the Eastern and Western music the way (Shankar) understood it, and interpreted it in such a way that people around the world were mesmerized by it," he said.

As well as Indian family and friends, Thursday's event -- at which speakers were flanked on stage by photos of Shankar at various stages of his life -- was attended by locals and other fans and followers.

"He's local, he's part of the community here," said Eddy Jimenez, a musician and trumpet player from Encinitas, comparing Shankar's influence and music to that of Harrison's fellow Beatle John Lennon.

"He's a bridge between humanity, really, not just East and West. I'm just here to pay my respects," the 61-year-old told AFP.

Gujarat election result: Gujarat Parivartan Party shrinks BJP win

RAJKOT: Former chief minister Keshubhai Patel's call for parivartan (change) may have met with indifference. But his Gujarat Parivartan Party (GPP) denied BJP a sweeter victory in the saffron stronghold Saurashtra. In absence of GPP, BJP was set to break the astronomical figure of 130 seats.

Results show that GPP presence has cost BJP at least 10 seats in Saurashtra namely Talala, Lathi, Palitana, Limdi , Wankaner, Rajkot(east), Jasdan, Jetpur, Dhoraji and Manavadar.

While Keshubhai himself trounced sitting MLA Kanu Bhalala in Visavadar, GPP's Nalin Kotadiya too defeated Dhari legislator Mansukh Bhuva to grab the seat. A former BJP man, Kotadiya had shifted loyalty to Keshubhai two months ago.

GPP played a spoilsport in Wankaner too where BJP had a bright chance of winning the seat back from Congress. Had GPP's Parsottam Bavalava not pocketed around 20,000 votes, BJP's Jitu Somani was sure to win considering that the sitting Congress MLA Javed Pirzada won by just 5,000 votes.

In Rajkot (east), BJP fielded Kashyap Shukla, son of one of BJP founders in state Chiman Shukla. But GPP's Pravin Ambaliya bagged around 15,000-20 ,000 votes, paving way for Congress to win this traditional BJP seat for the first time.

BJP's sitting minister of state for forests Kiritsinh Rana too has only GPP's candidate Pravinsinh Solanki to blame for his defeat. Solanki hails from Darbar community , the same as Rana's . He bagged 2,560 votes that led to Congress's Soma Ganda Patel scraping through by just 1,561.

GPP's Nathu Kamaliya also denied victory to BJP's Govind Parmar in Talala seat of Junagadh district by grabbing nearly 10,599 votes. There are around 20,000 Leuva Patels too in this constituency . The defeat of state BJP president RC Faldu's loss in Jamnagar (rural) seat is also being attributed to GPP's Pranjivan Kundaria.

Meanwhile, the ignominious defeat of Keshubhai's party also brought to fore that fact that regional parties or third fronts cannot become a force to reckon with. In the past, regional parties like Swatantra Party, Maha Saurashtra P arty, Maha Gujarat Janta Parishad, Rashtriya Congress, Kisan Majdoor Lok Paksha and Maha Gujarat Janta Party have tried to test their electoral mettle. But all remained a one-election wonder. "People in Gujarat do not accept regional parties. The main reason is that such parties don't have organizational support and rank and file to build the party," said political analyst.

Shankersinh Vaghela's infamous rebellion against BJP to form Rashtriya Janta Party (RJP) did not help the former chief minister for long. In the ensuing elections, voters ou rightly rejected RJP got just four seats.

Hollies Get Prickly for a Reason

With shiny evergreen leaves and bright red berries, holly trees are a naturally festive decoration seen throughout the Christmas season.

They're famously sharp. But not all holly leaves are prickly, even on the same tree. And scientists now think they know how the plants are able to make sharper leaves, seemingly at will. (Watch a video about how Christmas trees are made.)

A new study published in the Botanical Journal of the Linnean Society suggests leaf variations on a single tree are the combined result of animals browsing on them and the trees' swift molecular response to that sort of environmental pressure.

Carlos Herrera of the National Research Council of Spain led the study in southeastern Spain. He and his team investigated the European holly tree, Ilex aquifolium. Hollies, like other plants, can make different types of leaves at the same time. This is called heterophylly. Out of the 40 holly trees they studied, 39 trees displayed different kinds of leaves, both prickly and smooth.

Some trees looked like they had been browsed upon by wild goats and deer. On those trees, the lower 8 feet (2.5 meters) had more prickly leaves, while higher up the leaves tended to be smooth. Scientists wanted to figure out how the holly trees could make the change in leaf shape so quickly.

All of the leaves on a tree are genetic twins and share exactly the same DNA sequence. By looking in the DNA for traces of a chemical process called methylation, which modifies DNA but doesn't alter the organism's genetic sequence, the team could determine whether leaf variation was a response to environmental or genetic changes. They found a relationship between recent browsing by animals, the growth of prickly leaves, and methylation.

"In holly, what we found is that the DNA of prickly leaves was significantly less methylated than prickless leaves, and from this we inferred that methylation changes are ultimately responsible for leaf shape changes," Herrera said. "The novelty of our study is that we show that these well-known changes in leaf type are associated with differences in DNA methylation patterns, that is, epigenetic changes that do not depend on variation in the sequence of DNA."

"Heterophylly is an obvious feature of a well-known species, and this has been ascribed to browsing. However, until now, no one has been able to come up with a mechanism for how this occurs," said Mike Fay, chief editor of the Botanical Journal of the Linnean Society and head of genetics at the Kew Royal Botanic Gardens. "With this new study, we are now one major step forward towards understanding how."

Epigenetic changes take place independently of variation in the genetic DNA sequence. (Read more about epigenetics in National Geographic magazine's "A Thing or Two About Twins.")

"This has clear and important implications for plant conservation," Herrera said. In natural populations that have their genetic variation depleted by habitat loss, the ability to respond quickly, without waiting for slower DNA changes, could help organisms survive accelerated environmental change. The plants' adaptability, he says, is an "optimistic note" amidst so many conservation concerns. (Related: "Wild Holly, Mistletoe, Spread With Warmer Winters.")
