There are some studies have done on identification of gibberelline (GA) producing rhizobacterium, Pseudomonas species. In current study, we isolated and identified GA producing P. putida H- 2-3 from the agricultural field soil of chungcheongbuk-do, Danyang, Republic of Korea. The release of GAs from microbes to rhizosphere or plant root is a source of GA for plant growth.
