Abstract

The goal of the present study was to investigate the nucleotide sequence polymorphism of the Avr2 virulence gene in the population of P. infestans from Moscow region. The SSCP technique was applied for estimation of this polymorphism. As a result, the Avr2 gene was shown to have a high degree of polymorphism of the primary structure. In particular, seven variants of genotypes associated with the Avr2 gene polymorphism were identified. It was also found that the distribution of these genotypes among the samples of the studied population had a spatially dependent manner.
