Nodularin biosynthetic gene cluster from Nostoc sp. CENA543 (A) and evolutionary history of ndaF and mcyE genes (B). Neighbor-joining tree based on ndaF and mcyE genes in the adenylation domain and peptidyl carrier protein region. Bootstrap values above 50 percent of 1,000 replicates are given at the nodes. Strains that produce nodularin are highlighted in blue and Nostoc sp. CENA543 is blue and bold.
