摘要：

This work presents the results of molecular-genetic investigation of a new yeast genus, Lachancea Kurtzman (2003). Analysis of rRNA sequences and molecular karyotyping have shown genetic homogeneity of the genus Lachancea. Yeasts of this genus have an identical haploid number of chromosomes equal to eight, whereas limiting chromosome sizes significantly differ in various species. The largest range of chromosome bands was registered in L. cidri strains (400-2800 kb), while the smallest was found in L. waltii (1400-2800 kb). The intra- and interspecies polymorphism of Lachancea chromosomes is discussed.
