Metabolic fingerprinting: Using proteomics to identify proteins in gymnosperm pollination drops

Apr. 10, 2013 ? Proteins are vital parts of living organisms, performing a variety of essential functions such as DNA replication, catabolizing reactions, and responding to stimuli. The complete set of proteins expressed in an organism at a given time, under defined conditions, is known as the proteome. While the genome of an organism remains relatively stable, the proteome is remarkably dynamic, varying from cell to cell and even within a single cell and changing rapidly in response to developmental and environmental cues.

Proteomics is a powerful technique for examining the structure and function of the proteome. For some organisms, proteomics can uncover the relationship between DNA, RNA, and the production of proteins -- enabling the comparison of the genome to the proteome. For those organisms that have not yet been sequenced, proteomics facilitates the discovery and identification of proteins. In a new study published in the April issue of Applications in Plant Sciences, graduate student Natalie Prior and her colleagues demonstrate the suitability of proteomics in determining the composition of gymnosperm pollination drops.

"The biggest limitation in what we are doing is that there is no published gymnosperm genome," says Prior. "Most of the work on gymnosperms has been anatomical, histological, or morphological. The biochemical perspective is really lacking."

Mediating signaling between the pollen and the ovule, one role of the pollination drop is to provide a germination medium, which can be species specific. Additionally, in some species, anti-microbial proteins have been identified, suggesting that pollination drops provide protection in addition to acting as a landing spot for pollen grains.

"The proteins we are finding are really starting points for other research," says Prior. "We can identify these proteins, but there is a lot more research that can be done once we know what proteins are there."

Identification of the proteins found in pollination drops provides a metabolic fingerprint and thereby informs understanding of seed plant evolution. Comparing the proteomes of different species allows for identification of proteins, elucidating pollen-ovule interactions in gymnosperms.

"We are using proteomics to examine the biological relevance of the proteins that the pollen grain is exposed to in the drop," comments Prior. "It's fascinating to know if any of those proteins are consistent among groups of gymnosperms and what we can learn from that."

HTC One slated for April 19th release on T-Mobile

With all this talk about the cord-cutting masses no longer wanting to subsidize TV channels they don't watch, it's a little surprising that one of the oldest, most widely available forms of TV is waning: over-the-air broadcast TV. Despite its attractive price of $0 per month and billions of advertising revenue, nobody ? including the broadcast networks, the tech companies that are out to disrupt them, and the cord-cutters and cord-nevers who hate cable ? is very enthusiastic about antennas. ...

    Bird flu found on S.Africa ostrich farm, no Chinese link seen

    CAPE TOWN (Reuters) - An outbreak of bird flu has hit an ostrich farm in South Africa, but authorities said it was unlikely to pose a threat to humans, though additional tests were being carried out after another strain killed eight people in China.

    The outbreak has prompted restrictions on the movement of the big birds and their products in the Western Cape province, the Western Cape ministry of agriculture said in a statement on Tuesday.

    Tests samples from an ostrich farm near Oudtshoorn, the centre of South Africa's ostrich export industry, found the presence of the H7N1 virus, the ministry said.

    Another strain, H7N9, has killed eight people in eastern China since it was confirmed in humans for the first time last month.

    Marna Sinclair, a state vet in the Oudtshoorn area, said there had been previous incidents of H7N1 viruses in the region, but that none were found to be related to the current Chinese strain and no people have fallen ill.

    "There is no real concern. We doubt it is a related virus but are conducting tests to make sure," she said.

    Two years ago, South Africa culled 10,000 ostriches after an outbreak of another, less virulent form of bird flu halted ostrich-meat exports to the European Union.

    Falkland Islands mourn Thatcher, Argentines bitter over past

    By Hilary Burke and Karina Grazina

    BUENOS AIRES (Reuters) - Falkland Islanders mourned Margaret Thatcher on Monday, revering her as their liberator after a 1982 invasion by Argentine forces, but many Argentines bitterly recalled her role in defending the South Atlantic territory.

    Flags flew at half-staff on the Falklands after news of Thatcher's death on Monday aged 87. The head of the local legislative assembly said it was a day of great sadness and another resident praised her as "our Winston Churchill."

    In Buenos Aires, however, one resident named Jose Raschella, 48, said: "I hope God can forgive her because I can't."

    Thatcher sent a task force to recapture the islands, known in Argentina as Las Malvinas, in an operation she considered one of the triumphs of her 1979-1990 rule.

    Argentina still presses its sovereignty claim over the Falklands and in the past year has stepped up rhetoric against Britain despite a referendum last month in which the islanders overwhelmingly voted to stay British.

    "There's absolutely no doubt that Mrs. Thatcher had a special feeling for the Islands, she led a very difficult recapture of the Islands ... and the Falklands were always in her heart," Mike Summers, chair of the Falklands' eight-member assembly, told Reuters by telephone from Port Stanley.

    "She's a very much revered person in the Falklands for leading our return to freedom in 1982, and it will be a day of great sadness for Falkland Islanders."

    Summers said a memorial service would be held but it was not yet clear when.

    The barren and windy islands off the tip of Patagonia, at the southern end of South America, have a population of around 2,500.

    'WAR CRIMINAL'

    About 650 Argentines and 255 Britons were killed in the 1982 war, which started when Argentina's military leaders of the time ordered the invasion on April 2 and ended with the recapture of Port Stanley by British troops on June 14.

    The defeat helped bring an end to Argentina's dictatorship and many Argentines today see the war as a doomed and cynical move by the military leaders who murdered and "disappeared" thousands of their own people in a "dirty war" against suspected leftists.

    Nonetheless, most Argentines are convinced the islands belong to their country, viewing the issue as a patriotic cause.

    President Cristina Fernandez has piled pressure on Britain to negotiate the sovereignty of the islands - something London refuses to do unless the islanders themselves request talks.

    Thatcher's death stirred up angry memories in Argentina. On Twitter, left-leaning political groups celebrated the demise of a "war criminal."

    "The pain that she left our country can't be erased, we'll never forget all that pain," said Raschella, a musician.

    Carlos Grillo, a 63-year-old shop owner in Buenos Aires, said he had mixed feelings.

    "I hated her at that time, so I can't be impartial. I can't say 'I'm sorry (she died).' I'm not sorry," Grillo said. "But that goes against my Catholic faith, so I can't say I wanted it to happen either."

    The Argentine government made no official comment.

    'RIGHT PERSON, RIGHT TIME'

    Tim Miller, 60, owner of a Falkland Islands garden centre and store that sells patriotic gifts and memorabilia, recalled the 1982 conflict.

    "For me, she was for the Falklands what Winston Churchill was to Great Britain in 1940. She was the right person in the right place at the right time and did the right thing."

    Miller acknowledged that she was a divisive figure in Britain. "But to the Falklands she was our Winston Churchill."

    In Buenos Aires, while most people were pleased or indifferent about Thatcher's death, Alcides Francesco expressed some admiration for the British leader.

    "She was an English patriot," the 65-year-old worker said. "If we'd had several Margaret Thatchers here, the Falkland Islands would be ours."
