Fig. 2From: Evolution and conservation of polycomb repressive complex 1 core components and putative associated factors in the green lineagePhylogenetic tree of RING1 proteins in the Green Lineage. Plant RING1 homologs exist from algae to higher plants, and were subgrouped into three clades, Group-I seed plant, Group-II moss-fern, and Group-III algae. RING and RAWUL domains are the essential features of RING1 proteinsBack to article page
