Functional bias in molecular evolution rate of Arabidopsis thaliana.

ABSTRACT:

Background

Characteristics derived from mutation and other mechanisms that are advantageous for survival are often preserved during evolution by natural selection. Some genes are conserved in many organisms because they are responsible for fundamental biological function, others are conserved for their unique functional characteristics. Therefore one would expect the rate of molecular evolution for individual genes to be dependent on their biological function. Whether this expectation holds for genes duplicated by whole genome duplication is not known.

Results

We empirically demonstrate here, using duplicated genes generated from the Arabidopsis thaliana alpha-duplication event, that the rate of molecular evolution of genes duplicated in this event depend on biological funct
