Fig. 7From: Evolution and conservation of polycomb repressive complex 1 core components and putative associated factors in the green lineagePhylogenetic tree of VAL1/2/3 proteins in the Green Lineage. Plant VAL1/2/3 homologs exist from algae to higher plant, and were subgrouped into the three clades: Group-I VAL1 homologs existing in dicotyledons and group-II VAL2 and Group-III VAL2 homologs in angiosperm. B3 and zf-CW domains are the essential features of plant VAL1 proteinsBack to article page
