The researchers grew trees that LEAFY was still present Sandy Koufax Jersey , but RNA interference was applied to slow down the gene's activity in experimental field trials authorized by the U.S. Department of Agriculture in the Willamette Valley, Oregon, of the U.S. Pacific Northwest.


Before the trees flowered Maury Wills Jersey , the researchers collected hundreds of small twigs containing flower buds and studied the flowers that emerged in the laboratory.


"We noticed that some of the reproductive parts were tiny," Klocko was quoted as saying by a news release from OSU. "And we wondered if the flowers would have that same feature when they opened in the plantation. And they did."


By studying genetic activity in those trees, the researchers showed that the undeveloped flowers could be traced to the impact of RNA interference on the LEAFY gene.


"Our goal isn't to make reproductively modified trees just to have that trait Kirk Gibson Jersey ," said Klocko. "It's to prevent genetically modified or non-native trees from spreading, either to wild forests or to other plantations. This would help alleviate concerns over gene flow, whether for scientific or ethical reasons."


The finding Babe Herman Jersey , according to the researchers, could be applied to commercial plantations of fast-growing hybrid poplars, which are not genetically engineered in the United States.


Other reproductively modified trees Yasiel Puig Jersey , such as bananas, seedless oranges and many ornamentals, are commonly grown in agriculture and landscaping Adrian Gonzalez Jersey , but these trees have been produced using conventional forms of breeding such as hybridization and intentionally induced changes to DNA.


LEAFY has been known to be key to flower development for more than two decades. The use of RNA interference to change the expression of LEAFY is the first time genetic engineering technology has been used to produce a seedless forest tree of any kind, noted Steve Strauss, an OSU distinguished professor of forestry and a co-author on the paper.


And it is the first to show what would happen in a tree with modified LEAFY activity and grown in the field over several years Clayton Kershaw Jersey ,
