| Abstract: | It has been known that Microcystis exists as a mixed population of potentially toxic and non-toxic genotypes in a water body,but toxic and non-toxic Microcystis can not be distinguished by microscopy methods.In this study,we performed real time PCR assays to investigate the densities of the potential toxic subpopulation and the total Microcystis in Lake Chaohu,targeting the microcystin synthetase gene(mcyD) and the phycocyanin intergeic spacer,respectively.Water samples were collected from seven sampling si... |
