In this study, in order to increase the ability of phosphate solubilization of Escherichia coli DH5α, pqq gene cluster from Rahnella aqautilis HX2 was transformed into E. coli DH5α to create DH5α(pqq). Mechanisms of E. coli DH5α and DH5α(pqq) phosphate solubilization were analyzed by using solubilzing phospate on plate, molybdenum-blue method, HPLC, and greenhouse experiment. Compared with E. coli DH5α, strain DH5α(pqq) showed stronger mineral phosphate solubilizing ability, more gluconic acid production. Maize plant height, shoot fresh weight, plant fresh weight, shoot dry weight, plant dry weight, total phosphorus and soil solubling-P of DH5α(pqq) treatment were significantly(P<0.05) improved by 5.2%, 30.0%, 32.5%, 18.5%, 7.7%, 30.8%, and 24.0% respectively, compared with DH5α treatment. It was shown that pqq gene cluster from R. aqautilis HX2 strain showed activity in E. coli DH5α. This method may modify the other plant growth promoting rhizobacteria on phosphate solubilization trait. [ABSTRACT FROM AUTHOR]
