Detailed Description
Statement
Reference

Genotypes reared at 25oC died at 35oC. Flies reared at 29oC showed less significant differences in survival between genotypes than flies reared at 20oC and 25oC. Protein content, triglyceride content and ADH enzyme activity decreased significantly at 35oC, no correlation was observed between survival and these traits.

Egg to adult developmental time of Gpdh genotypes depends on the Adh genotype and temperature. Homoygotes have the slowest developmental time of all Gpdh genotypes, GpdhA/GpdhB heterozygotes have an intermediate development rate between the homozygotes. Adult weight of Gpdh genotypes interacts with temperature but not with Adh genotype. The Gpdh heterozygote has a significantly higher triglyceride content than the homozygotes which have a similar lower content, the values varied slightly in different Adh genotypes and temperatures. The differences in GPDH activity for all the Gpdh genotypes was small at all temperatures and Adh genotypes.

Homodimeric Gpdh enzyme encoded by GpdhB and heterodimeric Gpdh enzyme encoded by GpdhB and GpdhUF has been purified and characterised.

The frequency of the GpdhB allele in Eurasian natural populations increases in the Western part of Eurasia and is not associated with climatic variables.
