Figure 2From: The cinnamyl alcohol dehydrogenase gene family in Populus: phylogeny, organization, and expressionIntron-exon structures of CAD genes from Populus. Exons and introns are indicated by open boxes and lines respectively. Numbers above boxes indicate the exon sizes. The intron sizes are not to scale. The names of CAD genes and intron-exon structure are indicated at the left and right sides respectively.Back to article page
