  1. Gene fragments, pseudogenes and chloroplast-derived genes are excluded. Genes with the same number of copies in all five species are not included. aFrom bamboo (Acc. No. JQ235166 to JQ235179) [22], rice (Acc. No. BA000029) [21], maize (Acc. No. AY506529) [19], and wheat (Acc. No. AP008982) [27]. Lower case letter indicates exons of this gene.
