Detailed Description
Statement
Reference

Oviposition sites on standard medium and acetic acid supplement medium are studied.

If reared at 25oC homozygotes died at 35oC. Flies reared at 29oC showed less significant differences in survival between genotypes than flies reared at 20oC and 25oC.

Egg to adult developmental time of Adh genotypes depends on the Gpdh genotype and temperature. Homozygotes demonstrate fast development with all Gpdh genotypes, the AdhF/AdhS heterozygote shows an intermediate rate between the homozygotes. Adult weight of Adh genotypes is not affected by temperature or Gpdh genotype: Adh heterozygote is significantly heavier than the homozygotes, which have a similar weight.

Resistant to ethanol, sensitive to pentenol.

AdhF/AdhS flies are more resistant to the effect of high temperature.

pI of protein: 7.

The frequency of AdhF in a wine cellar was higher than AdhS. Statistical analysis demonstrates a significant increase of AdhF inside the cellar with respect to outside, and the converse situation or AdhS.

The analysis of within and between species polymorphism has shown a balanced polymorphism near position 1490, the site of the amino acid replacement difference (lys to thr) between AdhF and AdhS. The pattern of silent polymorphisms in the coding region can be explained by the presence of the single balanced polymorphism.

AdhF homozygote and the AdhF/AdhS heterozygote have a high adult male protein content within the temperature range analysed. The Adh heterozygote has a significantly lower triglyceride content than the homozygotes which have a similar higher content, the values varied slightly in different Gpdh genotypes and temperatures. At all the temperatures ADH activity in AdhF homozygotes is high in all Gpdh genotypes and the Adh heterozygote ADH activity is intermediate between the homozygotes.

Adult homozygotes have approximately twice the level of ADH activity and CRM as do D.simulans flies.

This allele fixed in lines selected for high geotaxis.

Protein content, triglyceride content and ADH enzyme activity decreased significantly at 35oC, no correlation was observed between survival and these traits.

Average Adh protein activity was higher in Chinese than Australian populations for AdhF and AdhS lines. There is a significant correlation between Adh protein activity and Adh protein levels. AdhF lines had more CRM than AdhS lines.

Homozygotes have decreased specific activities of Mdh1, Gpdh, Pgm, Idh, Me and Gapdh1 gene products. The differences between the enzyme quantities in AdhF homozygotes and AdhS homozygotes segregate as if caused by a single Mendelian gene with codominant alleles.

Gramoxone increases the frequency of the AdhS allele and decreases the frequency of the AdhF allele in the offspring of treated flies.

The frequency of the AdhS allele in Eurasian natural populations is negatively correlated with latitude and the average rainfall of the driest calendar month, and positively correlated with the average temperature of the coldest calendar month and the average rainfall of the wettest calendar month.

The influence of starvation on AdhS enzyme activity has been studied in D.melanogaster larvae and adults.

The influence of ethanol on AdhS enzyme activity has been studied in D.melanogaster larvae.
