Figure 1From: Distinct double flower varieties in Camellia japonica exhibit both expansion and contraction of C-class gene expressionSequence alignment and phylogenic analysis of CjAG. A, alignment of conserved regions of CjAG and related C- function orthologs. Two AG motifs were highlighted by underlines (Kramer [21]). B, a phylogenetic tree containing CjAG and other C- function othologs. Sequence information was listed in Additional file 2: Table S2.Back to article page
