| molecular characterization of potential microcystin-producing cyanobacteria in lake ontario embayments and nearshore waters. | the distribution and genotypic variation of potential microcystin (mc) producers along the southern and eastern shores of lake ontario in 2001 and 2003 were examined using a suite of pcr primers. cyanobacterial, microcystis sp., and microcystis-specific toxin primer sets identified shoreline distribution of cyanobacterial dna (in 97% of the stations) and mc synthetase genes (in 50% of the stations). sequence analysis of a partial mcya amplicon targeting microcystis, anabaena, and planktothrix sp ... | 2007 | 17526791 |
