Figure 2From: Comparative genome analysis of PHB gene family reveals deep evolutionary origins and diverse gene functionPhylogenetic tree of PHB genes across higher species. PHB protein sequences of four species from higher plants were analysed, unrooted tree was constructed using Neighbour-Joining method, bootstrap 1000 replicates, only the clades with bootstrap value higher than 50 were shown. The tree was classified into four classes, corresponding the Class II, III, IV, and V in the phylogenetic tree in Figure 1.Back to article page
