Figure 1From: Comparative genome analysis of PHB gene family reveals deep evolutionary origins and diverse gene functionPhylogenetic tree of PHB genes across different species. PHB protein sequences of nine species from four kingdom were analysed, unrooted tree was constructed using Neighbour-Joining method, bootstrap 1000 replicates, only the clades with bootstrap value higher than 50 were shown. Tree was divided into five classes, some were further divided into subclasses, each class has different color indicated. Several conserved genes could not be included into classes.Back to article page
