It has been shown that the studied variants of bread wheat plants are resistant to zinc deficiency in the substrate. Various ways of adaptation to these conditions by the antioxidant system have been discovered in plants that have a functional allele of the
GPC-B1
gene. Thus, in plants of line 15-7-1, the maintenance of the redox balance of cells is associated with an increase in the expression of the
Cu/ZnSOD
gene and a decrease in the expression of the
FeSOD
and
CAT1
genes, whereas in plants of line 13-3, in addition to an increase in the transcripts content of the
Cu/ZnSOD
gene, it is associated with a high constitutive activity of superoxide dismutase (SOD) and catalase (CAT). The data obtained can be used to create wheat varieties (lines) capable of producing seeds with a relatively high content of zinc under zinc deficiency in the soil.
