External factors accelerate expression divergence between duplicate
    genes

* *

*Misook Ha, Wen-Hsiung Li and Z. Jeffrey Chen*

We examined the evolution of expression of duplicate genes in 
/Arabidopsis thaliana/, by analyzing 512 data sets of gene expression 
microarrays and 2022 recent duplicate gene pairs. Expression divergence 
between gene duplicates is significantly greater in response to 
environmental stress than to developmental processes. A slow rate of 
expression divergence during development might offer dosage-dependent 
selective advantage, whereas rapid expression divergence in response to 
external changes might accelerate adaptation.
