Metabolic changes in tissues of club potatoes with different degree of resistance to bacteriosis
Abstract
Of the 17 varieties studied, it was found that the tubers of the varieties Vesnyanka and Zdabytak were sensitive to wet rot, Skarb, Krynitsa, Lazurit, Lileya, Orbita were moderately resistant, and Molly and Dolphin were the most resistant varieties. Among the resulting changes in the content of free amino acids and their derivatives, the most informative metabolic changes in potato tissue cells with varying degrees of resistance to bacteriosis are changes regarding the imbalance in the content of aspartic acid, glutamine, glycine, arginine, valine, methionine and phenylalanine, established between potato varieties , characterized by the highest resistance and the highest sensitivity to bacterial wet rot. There are 2 main categories of indicators: – leading – low concentration of arginine and methionine, high content of aspartic acid in potato varieties more sensitive to bacteriosis; – additional – lower concentrations of glutamine, glycine, valine and phenylalanine in potato varieties that are more sensitive to bacteriosis, which can be taken into account only in combination with the leading indicators and are of secondary diagnostic nature.
Supporting agencies: The work was carried out within the framework of the BRFFR Foundation № B17M-160 «Induced metabolic imbalance in the expression of PR genes in potato varieties with different resistance to bacterial diseases».
