Fig. 9From: Comparative and phylogenetic analyses of six Kenya Polystachya (Orchidaceae) species based on the complete chloroplast genome sequencesDistribution patterns of ndh gene loss in Orchidaceae. The blue, red, and yellow blocks indicate presence, pseudogene, and absence of each gene, respectively. 11 ndh non-normal genes are distributed widely across all taxonomic groups of Orchidaceae. Loss of ndh genes frequently occurs in Epidendroideae and VanilloideaeBack to article page
