In 12 different Russian and Kazakhstan potato cultivars, the polymorphism of the glycosyltransferase domain of the sucrose synthase gene was first examined, as well as the polymorphism of the sucrose synthase domain fragment of the same gene in the potato cultivars of Kazakhstan breed. It was demonstrated that the examined sequences contained point mutations, as well as insertions and deletions, including those not described earlier. Amino acid substitutions specific to heat- and drought-tolerant varieties were also identified and could be associated with the development of abiotic stress resistance.
