A phylogenetic tree and a schematic diagram for intron/exon structures of SET genes in Populus and Arabidopsis. (A) Unrooted tree constructed with NJ methods using SET domain amino acid sequences from Populus and Arabidopsis SET proteins. ML bootstrap values, Posterior probabilities from BI and NJ bootstrap values analyses are presented for each main clade. ML and NJ bootstrap values above 50%, and BI posterior probabilities greater than 0.90 analyses are shown. "-" represents the NJ or ML bootstrap values below 50 or the posterior probabilities low 0.90. There are eight subfamilies. The pink brackets followed by numbers denote duplicated gene pairs in Populus. (B) The intron-exon structure of the SET gene family in Populus and Arabidopsis.
