title: [Puffing in the regions of the esterase and ecdysterone genes in Drosophila lummei strains differing in beta-esterase expression].
abstract: Correlation between the activity of esterase and ecdysterone puffs was observed by comparison of puff expression in the areas of alpha- and beta-esterase genes localization and exogenous ecdysterone-sensitive areas (2-G-1-2-G-5). 2-G-5 puff expression and beta-esterase activation correlated with decrease of ecdysterone puffs activity. Constant puffing in 2-G-1 and 2-G-4 matched with constant activity of alpha-specific isoenzymes. The F1 larvae from cross between lines with normal and null-allele beta Est2 gene carried heteromorph puff and its expression depended upon cross direction.
