From: Convergent evolution of [D-Leucine1] microcystin-LR in taxonomically disparate cyanobacteria
Evolutionary history of adenylation domains of microcystin biosynthetic gene cluster. Maximum-likelihood tree based on amino acids sequences of adenylation domain within mcy gene cluster. Phylogenetic tree inferred using MEGA 5. Bootstrap values above 50 per cent from 1000 respectively neighbor-joining, maximum parsimony and maximum-likelihood bootstrap replicates are given at the nodes. The studied strains are in bold and indicated with *.
