摘要
Genetic variation at 27 enzyme loci was studied in 24 Transcaucasian populations of Aegilops squawosa: 12 ssp. eusquarrosa and 12 ssp. strangulata populations. Most of the genetic variation was among populations: GST accounted for 0.67 and 0.64 for ssp. eusquarrosa and ssp. strangulata, respectively. The Acph1, Est2, Esr5, Gor1 and Got2 loci were found to be involved in the adaptive process of Ae. squarrosa subspecies divergence. Allele variation at the Ep locus is most likely to be neutral. The remaining 21 enzyme loci are under purifying selection of different intensities.
