ELECTROPHORETIC VARIANTS OF α-GLYCEROPHOSPHATE DEHYDROGENASE IN THE FIRE ANTSOLENOPSIS INVICTA

Abstract
.alpha.GPDH (.alpha.-glycerophosphate dehydrogenase, EC 1.1.1.8) exists in the fire ant S. invicta Buren in 2 isozymic forms representing 2 loci. The 2 isozymic forms are tissue specific and differentially expressed in different developmental stages and physiological states. GPDH-2 is monomorphic. GPDH-1 is polymorphic with fast and slow alleles. Clear differences in resistance to heat and urea denaturation were observed both between and within the 2 mobility classes.
