Nonrandom divergence of gene expression following gene and genome duplications in the flowering plant Arabidopsis thaliana.

ABSTRACT:

Background

Genome analyses have revealed that gene duplication in plants is rampant. Furthermore, many of the duplicated genes seem to have been created through ancient genome-wide duplication events. Recently, we have shown that gene loss is strikingly different for large- and small-scale duplication events and highly biased towards the functional class to which a gene belongs. Here, we study the expression divergence of genes that were created during large- and small-scale gene duplication events by means of microarray data and investigate both the influence of the origin (mode of duplication) and the function of the duplicated genes on expression divergence.

Results

Duplicates that have been created by large-scale duplication events and that can still be found in duplicat
