Microcystin Biosynthesis andmcyAExpression in Geographically DistinctMicrocystisStrains under Different Nitrogen, Phosphorus, and Boron Regimes [PDF]
BioMed Research International, 2016 Roles of nutrients and other environmental variables in development of cyanobacterial bloom and its toxicity are complex and not well understood. We have monitored the photoautotrophic growth, total microcystin concentration, and microcystins synthetase gene (mcyA) expression in lab-grown strains ofMicrocystisNIES 843 (reference strain), KW (Wangsong ...

First report of potentially microcystin-producing Microcystis in the Dominican Republic [PDF]
Current Research in Microbial SciencesSummary: When the amount of nutrients in water bodies increases, cyanobacteria tend to proliferate rapidly in freshwater lakes and reservoirs, which can trigger cyanobacterial blooms.

International Journal of Secondary Metabolite, 2020 The cyanotoxin microcystin (MC) is a secondary metabolite, synthesized by nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) enzymes. It has many isoforms and the mechanism of its diversity is not well understood. One of the MC synthetase genes, mcyA, codes for the McyA module containing two adenylation (A) domains.
