Fig. 4From: Identification and co-evolution pattern of stem cell regulator miR394s and their targets among diverse plant speciesAn unrooted NJ phylogeny of pre-MIR394s using MEGA6. The tree is sub-divided into cluster I and II represented in pink and blue colour, respectively. The pre-MIR394 sequences has shown discrete evolution pattern with varying substitution rate. The scale bar represents the nucleotide substitution rateBack to article page
