Identification of genes implicated in toxin production in the cyanobacterium Cylindrospermopsis raciborskii

Examination of the strain‐specific distribution of the PKS and PS genes in C. raciborskii isolates demonstrated a direct link between the presence of these two genes and the ability to produce cylindrospermopsin, suggesting a likely role for these determinants in secondary metabolite and toxin production by C. raceskii.
