文摘

The structure of the hsp70 gene cluster was investigated for two species of the family Stratiomyidae (Diptera), Stratiomys singularior and Oxycera pardalina. Their larvae inhabit nearshore-aquatic biotopes with contrasting temperature regimes, composition and concentration of salts. It was shown that the S. singularior hsp70 gene cluster contains five copies and has a compact structural organization (the interval length did not exceed 5 kb). The O. pardalina hsp70 gene cluster contains four copies located at larger distances in comparison with the S. singularior and also includes the hsp68 gene. High variability in the structure of the S. singularior hsp70 gene cluster was detected.
