Esterase-2 in Ephestia kühniella. II. Tissue-specific patterns

  • Friedrich Leibenguth

Abstract

Esterase-2 polymorphism has been investigated quantitatively. Staining intensities of the homodimer bands mm, ff, and ss are not equally expressed but found in relative activities of 1:0.5:0.7 in fat bodies and 1:1:3 in testes and gut walls. Relative intensities of the parental bands are binomially distributed in the three-banded patterns of heterozygotes in an exactly tissue-specific manner. Organ-specific proportions of relative activity remain constant throughout postembryonic development. Among reasons which may influence genesis of allele- and organ-specific activities of homodimer bands in homozygotes and may lead to asymmetrical distribution of intensities in the patterns of heterozygotes, a hypothesis of differential allelic activity is discussed, according to which the structural alleles 2 m , 2 f , and 2 s are closely linked to the alleles RG a , RG b , and RG c of a controlling gene.
