What biochemical mechanisms help plant plants to defend themselves from pests, scientists of Vir them will be studied. N.I. Vavilov, together with colleagues from the institute of vegetable and decorative cultures. Leibnia (Germany).
For three years (up to 2023), researchers will work within the framework of the grant RFBR and the German Research Community (DFG).
Cruciferous vegetables, such as color, Brussels cabbage, broccoli, turnip, and others, in addition to containing vitamins, minerals and fiber, have chemishenic substances - glucosinolates that splitting compounds called secondary metabolites.
Metabolites do not participate in the growth, development or reproduction of the plant, and perform "environmental" functions, for example, protect the plant from various pests and pathogens, giving the cross-cooler vegetables a distinctive bitter taste and acute flavor.
In their preceding studies, scientists of Vir them. N.I.Vavivova and the institute of vegetable and decorative cultures. The leibitus found that if the structure of substances - glucosinolates, in general, uniform, then the products of their decay - metabolites - have significant variability. Such a variety leaves still far to understand the role of secondary metabolites in the process of the interaction of the plant and the insect. Especially, in combination with various food preferences of sheet-raging pests of cabbage cultures.
"The results of the project will be expected to gain knowledge of the role of secondary metabolites in the protection of plants, the possibilities of combining in one genotype - a complete set of organism genes - various mechanisms of biochemical stability, the spread of the main pests of cabbage cultures in different regions of Russia and the methods of increasing insect sustainability Capulate crops, "says the head of the Department of Vegetable and Bakhchy Cultures Vir. N.I. Vavilov Anna Artemieva.
The study of the peculiarities of the content of secondary metabolites in cruciferous vegetables, the ratios of this content, as well as the susceptibility of plants in the formation of protective mechanisms will be carried out on the basis of the collection of the genetic resources of VIR. N.I. Vavilov.
