    General Introduction:

    Harmful cyanobacterial mass occurrences are a worldwide environmental problem. Toxic cyanobacterial blooms have become a threat to drinking and recreational water systems. Identifying the species of water bloom forming cyanobacteria and monitoring the occurrence of toxic cyanobacterial blooms would help to protect water bodies and water users. It is becoming more necessary and reliable to characterize cyanobacterial taxa using the integrated approach including morphological, physiological, biochemical and genetic features. Based on morphological observations and culture strains, some important genes from typical water bloom forming cyanobacteria have been intensively investigated in this research group to elucidate the evolutionary course of cyanobacterial organisms and some environmental problem related genes .

    The main research interests of this group include: 1) Diversity and phylogeny of cyanobacteria, especially water bloom forming cyanobacteria; 2) Molecular monitoring of toxic cyanobacteria in Chinese waters as a warning tool to drinking water system; 3) Evolutionary history among cyanobacterial organisms using multi-genetic and genomic evidences. 4) Evaluation of the methods applied in control of water blooms by examining the bio-safety of the methods.
