Intron/exon structure of representative genes of each subfamily. The intron/exon structures of representative genes of each subfamily were determined by comparison of the CDS with their corresponding genomic DNA sequences and were displayed using GSDS [43]. The IDs of representative genes of each subfamily are included in brackets. “AO” in the top left corner of a subfamily name indicates that members are only present in A. thaliana or O. sativa. “PAO” in the top left corner of a subfamily name indicates this subfamily members are only present in P. patens, A. thaliana or O. sativa, but not present in S. moellendorffii. a Subfamilies with intron/exon structures conserved in P. patens, S. moellendorffii, A. thaliana, and O. sativa. b Subfamilies with intron/exon structures conserved in S. moellendorffii, A. thaliana, and O. sativa. c Subfamilies with intron/exon structures were conserved in A. thaliana and O. sativa
