Fig. 1From: Genome sequence of Apostasia ramifera provides insights into the adaptive evolution in orchidsGene family and phylogenetic relationship analysis. (A) Venn diagram showing distribution of shared gene families among five orchid species, i.e., A. ramifera (Ara), A. shenzhenica (Ash), P. equestris (Peq), D. catenatum (Dca), and V. planifolia (Vpl). (B) Phylogenetic tree showing relationship and divergence times for 16 species. Purple bars at internal nodes represent 95 % confidence interval of divergence times. Numbers of expanded and contracted gene families are presented as green and red values, respectively. MRCA, most recent common ancestorBack to article page
