| Them aim scope of this study is to characterize the enzymatic polymorphism found in the Melipona quadrifasciata Lepeletier, 1936 populations from Ribeirão Preto, São Paulo and Espírito Santo, Brazil and its hybrids. Samples from each colony (about 52) were prepared for starch gel electrophoresis in order to investigate the genetic variation of the following enzimes: esterase (EST), isocitrate dehydrogenase (IDH), malic enzyme (ME), phosphoglucomutase (PGM), superoxide desmutase (SOD), α-glycerophosphate dehydrogenase (αPGD), malate dehydrogenase (MDH), leucine aminopeptidase (LAP), hexokinase (HK) and phosphoglucose isomerase (PGI). The analysis showed that LAP and HK did not show enzymatic activity and EST showed two alleles(est-sand and est-f) while all... |
