Phylogenetic tree, motif compositions, and gene structures of trihelix genes. a Unrooted neighbor-joining phylogenetic tree. The tree was built using trihelix protein sequences of Arabidopsis, rice, B. distachyon, and wheat. b Schematic representation of conserved motifs. Colored boxes indicate different conserved motifs. c Exon/intron organization. Exons are shown as yellow boxes, and introns are shown as gray lines
