Fig. 6From: Evolution and conservation of polycomb repressive complex 1 core components and putative associated factors in the green lineagePhylogenetic tree of VRN1 proteins in the Green Lineage. Plant VRN1 homologs only exist in dicotyledons and were subgrouped into the two clades: Group-I AtVRN1a/RTV1 and group-II AtVRN1b/1c/1d. B3 domain is the essential features of plant VRN1 proteinsBack to article page
