Title: | Adaptive significance of amylase polymorphism in Drosophila: Effect of substrates with different carbohydrate composition on some life-history traits of Drosophila subobscura | Authors: | Savic, T. Milanovic, M. Stamenković Radak, Marina Andjelkovic, M. |
Issue Date: | 1-Mar-2008 | Journal: | Russian Journal of Genetics | Abstract: | The Amy locus polymorphism of Drosophila subobscura is used as a model system for an experimental population genetic study of adaptive significance of α-amylase activity on substrates of different carbohydrate compositions. So far, fitness components have not commonly been included in ecological-genetic studies of α-amylase polymorphism in this species. In the present paper, fitness components are analyzed in relation to different amylase activities in D. subobscura individuals homozygous for the "slow" and the "fast" Amy allele, associated with substrates of different carbohydrate compositions. The results indicate a significant effect of substrate carbohydrate composition on fitness components of the genotypes homozygous for S or F Amy allele in D. subobscura through their enzyme activity. © 2008 MAIK Nauka. |
