Figure 3From: Convergent evolution of [D-Leucine1] microcystin-LR in taxonomically disparate cyanobacteriaPhylogenetic analysis of the 16S rRNA gene. Maximum-likelihood tree based on the 16S rRNA gene. Bootstrap values above 50% from 1000 maximum-likelihood bootstrap replicates are given at the nodes. The studied strains are in bold and highlighted. Symbols for microcystin variants in position one: ● [D-Ala1]; ■ [D-Leu1]; ★ [D-Met1]; ◣ [D-Ser1].Back to article page
