Multiple ancient genome duplications in Arabidopsis thaliana provide unique opportunities to assess factors that influence the fates of duplicated genes. We have found that genes retained in duplicate following one round of genome duplication are significantly more likely to be retained in duplicate again after a subsequent genome duplication. Genes retained in duplicate form a functionally biased set and include a significant over-representation of genes involved in the regulation of transcription.
