Cím:	Comparative influence of Odh and Adh loci on alcohol tolerance in Drosophila melanogaster / Katalin Bokor, Katalin Pecsenye
Dátum:	1998
Megjegyzések:	The effect of ethanol on larva-to-pupa and larva-to-adult survival was compared in ten laboratory strains of Drosophila melanogaster. The strains had five different allele combinations at the Adh and Odh loci. Two parallel strains of the five two-locus genotypes were isolated from different isofemale lines, and so they had different genetic backgrounds. Second instar larvae of all ten strains were exposed to different ethanol treatments and larva-to-pupa and larva-to-adult survival components were estimated. The strains with different genetic background but identical genotypic combinations at the Adh and Odh loci had different initial survival rates but they exhibited similar tolerance to ethanol. Ethanol tolerance appeared to depend predominantly on the Odh locus. The two Adh genotypes did not show significantly different ethanol tolerance. In contrast, the three Odh genotypes tolerated exogenous ethanol differently: O Fdh homozygotes had the highest tolerance to ethanol in both the larval and pupal stages.

Cím:	A comparison of the level of enzyme polymorphism in cosmopolitan Drosophila species between populations collected in distilleries and in their surroundings in Hungary / K. Pecsenye
Dátum:	1989
Megjegyzések:	The level of enzyme polymorphism was studied in populations of Drosophila melanogaster and D. hydei from three different regions of Hungary. Collections were made in distilleries or by outside baits. Allozyme variability was investigated for five loci (Adh, Odh; Mdh; a-Gpdh; a Amy) by means of polyacrylamide gel electrophoresis. Two different rare alleles were detected for the Adh locus in D. hydei in Hungary. The number of species was lower in distilleries than outside. The heterozygosity level in samples from distilleries was generally lower than in samples from outside. This result gives support to the hypothesis that the more diverse the environment the higher the level of polymorphism maintained.
