The role of poliphenols in formation of fungicidal activity and resistance to exometabolites of the fungus on the example of in vitro crops sunflower and savory

Abstract

When studying the formation of secondary metabolites represented by phenolic compounds in callus cultures of sunflower plants, it was found that under in vitro conditions under the influence of a stress factor, the accumulation of polyphenols increases. It was found that the biosynthetic activity of callus cultures with respect to polyphenol increases in proportion to the concentration of the culture filtrate of the fungus (Sclerotinia Sclerotiorum) in the nutrient medium. This is confirmed by the qualitative and quantitative determination of the content of polyphenols in callus cultures. In savory plants, when introduced into culture in vitro, there is a sharp decrease in the biosynthesis of phenolic compounds. Ethanol extracts of microclones and callus cultures showed no fungicidal activity.
