Keywords: crack the root-knot nematode genome
[] Hearing: a France, United Kingdom, United States and Italy, a group of researchers has succeeded in breaking a nematode genome. According to experts, this outcome will provide insight on crop unwanted similar parasites of the genetic mechanisms, and is expected to serve as the basis to develop new methods of pest control.
Participation in the Research Institute of France national agronomic 28 day communiqué said, there is a known nematode species about 2.5 million, the vast majority of them exist in the soil, the roots of the parasitic plant, affect the host plants of normal growth, and ultimately lead to plant death. Each year a large number of crops under the influence of parasitic nematodes, the resulting economic losses amounting to billions of euros. At present a common approach to the eradication of nematodes are sprayed pesticides, but because of the toxicity of pesticides has certain, will have an impact on human health, so look for alternatives to become a top priority.
The Communique says, the researchers this solved a root-knot nematode genome. On genome analysis indicates that the root-knot nematode genes and bacteria are very similar, this description might exist between the two "gene transfer" phenomenon, because it may be beneficial to root-knot nematode parasitism in plants.
Research leader Pierre · Abad, root-knot nematodes have extremely strong vitality and adaptability, new research results will help people learn from the genetic point of view of these characteristics.
The study results published in the latest issue of the United Kingdom the nature-biotechnology Magazine Online Edition.
