Genomic background drives the divergence of duplicated amylase genes at synonymous sites in Drosophila.

Molecular biology and evolution - 1 Feb 2004

Zhang Ze, Kishino Hirohisa

Abstract excerpt

In some Drosophila species, there are two types of greatly diverged amylase (Amy) genes (Amy clusters 1 and 2), each encoding active amylase isozymes. Cluster 1 is located at the middle of its chromosomal arm, and the region has a normal local recombination rate. However, cluster 2 is near the centromere, and this region is known to have a reduced recombination rate. Although nonsynonymous substitutions follow a...
