Figure 2: A Neighbor-joining phylogenetic tree of chalcone synthase (CHS) amino acids sequences. The cluster containing all anther-specific CHS-like enzymes is highlighted. Bootstrap values from 1,000 replicates were used to assess the robustness of the trees. Only bootstrap values above 75% are indicated at the nodes. Accession numbers for genes from other species are given in Supplementary data.
