| Outline of Final Research Achievements |
Phosphorus supplying bacteria (PSB) can convert unavailable phosphorus to available phosphorus in soils, therefore application of PSB is expected to utilize unavailable phosphorus accumulated in soils for crop cultivation. However, non-symbiotic PSB has poor colonization ability on the surface of crop seeds and in the rhizosphere. The objective of this research is improve PSB's fitness in crop rhizosphere by focusing on bacterial biofilm formation. After screening of PSB mutants generated using transposon mutagenesis, PSBs having better ability to form biofilms were successfully isolated. These PSBs showed better performance of colonization on crop seeds and are expected to utilize for crop cultivation.
