| Outline of Final Research Achievements |
Synechocystis sp. PCC6803 forms biofilm under salt stress condition. The genetic and biochemical analyses were performed to reveal the mechanism of biofilm formation induced by salt stress. As consequences, we revealed the contribution of the two-component system in Synechocystis biofilm formation and one of the signal transduction pathway. Moreover, the possibility of biofilm regulation by c-di-GMP synthesis was also suggested.
