Figure 3From: Phylogenetic analysis of pectin-related gene families in Physcomitrella patensand nine other plant species yields evolutionary insights into cell wallsPolygalacturonase family tree. Four monophyletic clades (blue, pink, green, and yellow clouds) contain monocot, eudicot, Selaginella, and Physcomitrella genes. The tree contains two large polytomies, indicated in light grey and labeled “A” and “B”. Polytomy B contains unresolved Physcomitrella and Selaginella members. The algal root gene is from C. reinhardtii, a chlorophytic alga.Back to article page
