Can plants be altruistic? You bet, says new CU-Boulder-led study
Monday, February 4, 2013
We've all heard examples of animal altruism: Dogs caring for orphaned kittens, chimps sharing food or dolphins nudging injured mates to the surface. Now, a study led by the University of Colorado Boulder suggests some plants are altruistic too.
The researchers looked at corn, in which each fertilized seed contained two "siblings" -- an embryo and a corresponding bit of tissue known as endosperm that feeds the embryo as the seed grows, said CU-Boulder Professor Pamela Diggle. They compared the growth and behavior of the embryos and endosperm in seeds sharing the same mother and father with the growth and behavior of embryos and endosperm that had genetically different parents.
"The results indicated embryos with the same mother and father as the endosperm in their seed weighed significantly more than embryos with the same mother but a different father," said Diggle, a faculty member in CU-Boulder's ecology and evolutionary biology department. "We found that endosperm that does not share the same father as the embryo does not hand over as much food -- it appears to be acting less cooperatively."
A paper on the subject was published during the week of Jan. 21 in the Proceedings of the National Academy of Sciences. Co-authors on the study included Chi-Chih Wu, a CU-Boulder doctoral student in the ecology and evolutionary biology department and Professor William "Ned" Friedman, a professor at Harvard University who helped conduct research on the project while a faculty member at CU-Boulder.
Diggle said it is fairly clear from previous research that plants can preferentially withhold nutrients from inferior offspring when resources are limited. "Our study is the first to specifically test the idea of cooperation among siblings in plants."
"One of the most fundamental laws of nature is that if you are going to be an altruist, give it up to your closest relatives," said Friedman. "Altruism only evolves if the benefactor is a close relative of the beneficiary. When the endosperm gives all of its food to the embryo and then dies, it doesn't get more altruistic than that."
In corn reproduction, male flowers at the top of the plants distribute pollen grains two at a time through individual tubes to tiny cobs on the stalks covered by strands known as silks in a process known as double fertilization. When the two pollen grains come in contact with an individual silk, they produce a seed containing an embryo and endosperm. Each embryo results in just a single kernel of corn, said Diggle.
The team took advantage of an extremely rare phenomenon in plants called "hetero-fertilization," in which two different fathers sire individual corn kernels, said Diggle, currently a visiting professor at Harvard. The manipulation of corn plant genes that has been going on for millennia -- resulting in the production of multicolored "Indian corn" cobs of various colors like red, purple, blue and yellow -- helped the researchers in assessing the parentage of the kernels, she said.
Wu, who cultivated the corn and harvested more than 100 ears over a three-year period, removed, mapped and weighed every individual kernel out of each cob from the harvests. While the majority of kernels had an endosperm and embryo of the same color -- an indication they shared the same mother and father -- some had different colors for each, such as a purple outer kernel with yellow embryo.
Wu was searching for such rare kernels -- far less than one in 100 -- that had two different fathers as a way to assess cooperation between the embryo and endosperm. "It was very challenging and time-consuming research," said Friedman. "It was like looking for a needle in a haystack, or in this case, a kernel in a silo."
Endosperm -- in the form of corn, rice, wheat and other crops -- is critical to humans, providing about 70 percent of calories we consume annually worldwide. "The tissue in the seeds of flowering plants is what feeds the world," said Friedman, who also directs the Arnold Arboretum at Harvard. "If flowering plants weren't here, humans wouldn't be here."

Monkey business? US unsure of Iran's space claims
CAPTION CORRECTION, REMOVES SECOND SENTENCE AND ADDS NEW INFORMATION THAT THE MONKEY DEPICTED IN THE PHOTO IS NOT THE SAME ONE THE IRANIANS SENT INTO SPACE - In this picture obtained from the Iranian Students News Agency, ISNA, scientists surround a monkey ahead of a space launch in an undisclosed location in Iran. One of two official packages of photos of Iran's famed simian space traveler depicted the wrong monkey, but a primate really did fly into space and return safely to Earth, a senior Iranian space official confirmed Saturday. One set of pictures showed a relatively dark-haired monkey. Another showed a different monkey, the one shown in this photo, strapped in a pod, that had light gray hair and a distinctive red mole over its right eye. State TV pictures seen by AP show the dark-haired monkey before and after the space flight, but a package of still pictures released by authorities showed the above monkey with the mole.

WASHINGTON (AP) ? The United States expressed doubt on Monday about Iran's claim that it safely returned a monkey from space, saying it is questionable that the monkey survived ? or if the flight happened at all.
State Department spokeswoman Victoria Nuland said a lot of questions remained "about whether the monkey that they reportedly sent up into space and reportedly came down was actually the same monkey, whether he survived."
"The Iranians said they sent a monkey, but the monkey that they showed later seemed to have different facial features," Nuland told reporters. "He was missing a little wart."
Tehran blames the confusion on Iranian media for initially using a photo of a backup monkey. It says the monkey orbited and returned safely, and President Mahmoud Ahmadinejad added Monday that he would consider being Iran's first astronaut in space.
Nuland described Ahmadinejad's proclamation as an "interesting choice," but was more diplomatic than Sen. John McCain, R-Ariz., who joked about Ahmadinejad's ruminations earlier Monday.
"Wasn't he just there last week?" McCain said in a tweet and linked to a story about the space-orbiting monkey.
Faced with criticism, McCain said in another tweet, "lighten up folks, can't everyone take a joke." But it wasn't funny to Michigan Rep. Justin Amash, a Republican, who tweeted, "Maybe you should wisen up & not make racist jokes."
Jonathan McDowell, a Harvard astronomer who tracks rocket launchings and space activity, backed up Iran's claim that monkey space flight was real. However, he had a slightly different explanation for the photo mix-up, saying the simian with the mole died during a failed space mission in 2011.
Iran has never confirmed that a monkey died in 2011, or that there was a failed mission that year.
Tehran says its goal is a manned space flight.
Washington and its allies worry the program may be cover for ballistic missile technology development.

Panetta says politics at play in Hagel questioning

WASHINGTON (AP) ? Defense Secretary Leon Panetta said "the political knives" came out when Chuck Hagel faced fellow Republicans on the Senate Armed Services Committee during his confirmation hearing to be Pentagon chief.
Panetta said he was disappointed that Thursday's eight-hour hearing focused so much on what Hagel, a former Republican senator from Nebraska, had said in the past about Iran, Israel and other matters instead of what he thinks about today's issues, including the war in Afghanistan, the fight against terrorism, and looming automatic budget cuts and their impact on military readiness.
"We just did not see enough time spent on discussing those issues. And in the end, that's what counts," Panetta told NBC's "Meet the Press" in an interview broadcast Sunday.
"It's pretty obvious that the political knives were out for Chuck Hagel," Panetta said.
Senate Majority Leader Harry Reid, noting the lengthy hearing, said on ABC's "This Week," ''give the guy a break. I thought he did pretty good." Reid, D-Nev., said Hagel's party affiliation "should be a plus. We need more."
Panetta said he is confident that Hagel is prepared to succeed him at the Pentagon.
In an appearance on CNN's "State of the Union," Panetta dismissed concerns that Hagel and former Sen. John Kerry, D-Mass., who was sworn in Friday as secretary of state, agree with Obama's views to the point that they won't challenge the president.
"I've got to tell you, anybody who knows John Kerry and anybody who knows Chuck Hagel ... they push back. Believe me, they push back on the issues," he said. "In the situation room, everybody has to give their honest views. And I think they won't hesitate to give their honest views."
Two Republican senators, Thad Cochran of Mississippi and Mike Johanns of Nebraska, have said they will support Hagel's nomination. Johanns said Saturday his concerns were allayed after Hagel's Senate hearing and after he met with Hagel for an hour.
"Chuck earned this endorsement," Johanns said in an interview with the Lincoln (Neb.) Journal Star.
