Abstract
Objective: To provide scientific data for studying the ecology of cyanophage, we studied the genetic diversity of psbA of cyanophage from paddy floodwater in northeast China and its phylogenetic positions.
Methods: Membrane separation and concentration of cyanophage, PCR-cloning-sequencing were applied to study the diversity of psbA of cyanophage from paddy floodwater in northeast China.
Results: In total 17 psbA sequences of cyanophage were obtained. Novel cyanophages were found by phylogenetic analysis. Compared to those of Japanese paddy floodwater, marine and lakes, psbA gene assemblage of paddy floodwater in northeast China was significantly different.
Conclusion: This is the first report to study genetic diversity of cyanophage from paddy floodwater in northeast China with a molecular marker of psbA by PCR-cloning-sequencing. The novel psbA assembly of cyanophage was found in paddy floodwater in northeast China.
