The expression patterns of homoeologous gene pairs revealed by cDNA-SSCP analysis. We examined a total of 34 duplicated genes to investigate the variation in gene expression patterns between the genes in each pair. The cDNA-SSCP analysis of three different types of duplicated genes, combined with PAGE, was used to reveal divergence in gene expression patterns among genes (Gene 19 represented BBCC_CC bias, Gene 43 represented BBCC_BB bias and Gene 22 represented coexpressed). Coexpressed: both copies are expressed normally; BBCC_BB bias: copy from the BB subgenome is expressed, but the one from the CC subgenome is not expressed; BBCC_CC bias: copy from the CC subgenome is expressed, but the one from the BB subgenome is not expressed.
