Genetic mapping of yeast genes ACP5, acp83 and ACP82 was performed. According to the results obtained, ACP5 and acp83 are located in the chromosome VI and ACP82--in the chromosome XVI. Based on identity of chromosome location and phenotypes of mutations arising, it was proposed that ACP5 and acp83 are homologous to PHO4 and pho82 genes, respectively, and ACP82--to PHO85 in the yeasts of the same line.
