Fig. 3From: Evolution and conservation of polycomb repressive complex 1 core components and putative associated factors in the green lineagePhylogenetic tree of BMI1 proteins in the Green Lineage. Plant BMI1 homologs exist from algae to higher plants, and were subgrouped into two clades: Group-I BMI1a/1b homologs existing from algae to higher plant; and group-II BMI1c homologs specially in Cruciferae. RING and RAWUL domains are the essential features of BMI1 proteinsBack to article page
