Genes may help to reduce pollution

Genetically modified crops of long-term opponents, from the fear of the potential of traditional crops and other plant pollution. Now scientists at the University of Guelph have discovered that a plant gene may help to reduce the risk of farmers' GM contamination, and to quell the argument against the use of genetically modified crops, said Sharif Sharif, a new research paper, the results of the main authors.

This is considered to be the first study ever to find genes involved in altering the normal cross pollination of fruit trees - the need for one plant to another fertilization - into self - pollination, said Sheriff.

The paper was published in the Journal BMC biology.

Sheriff said the researchers may have one day to insert the gene into GM crops, to prevent its pollen from reaching other plants.

Plant a professor of agriculture at the Jay Subramanian, Nawaz Sharif, student mentor and the co-author, said: "there are a lot of global GM crops from creating a 'them to fertilization in wild populations and about the pollen. Super weed. "

Researchers have found that a genetically made protein is naturally a very small number of plants that are self - pollination and fruit. Peach, for example, have been receiving flowers, unlike those in need of pollen of another tree tree fertilization and set the fruit showy flowers of plum and cherry's cousin.

Subramanian study of fruit trees in the vineyard research and innovation center of the vineyard, Ontario province. Sheriff had worked with him on the study of plants to stress, such as drought or disease.

In the paper co authors are at the University of Guelph professor jaideep Mathur, molecular and cell biology department and Gopi Paliyath plants Agiruclture system. With the Islamic El-Sharkawy, had any researcher Arvind Subramanian with; and colleagues at the National University of Singapore.

In addition to helping farmers and food producers, their findings could be a boon for the perfume maker, Subramanian said.

In the use of perennial such as jasmine, the gene may keep off the flowers, let growers to collect more by perfume maker valuable aromatic compounds. "When the peaks of volatile compounds," Subramanian said. "When the flowers bloom, you lose almost 80% of the proportion of volatile substances."

Most plants develop open flowers that attract pollination, but it takes energy to make flowers as well as nectar and pollen. Subramanian said that the closure of flowers and plants - known as the closed flower fertilization, or Greece's "closed marriage" - may be in the development of a lack of pollination media environment or adverse conditions.

"This is the first time that we have known that it has been shown that the use of molecular tools can induce the closure of flowers and plants," he said.
