[Transposon tnPhoA mutagenesis as a method of obtaining mutants of Azospirillum brasilense by motility and flagellation].

Molekuliarnaia genetika, mikrobiologiia i virusologiia - 1 Jan 2000

Katsy E I, Shelud'ko A V

Abstract excerpt

Three A. brasilense strains (S27, SpBr14, and KR77) did not hydrolyze the chromogenic substrate of alkaline phosphatase (PhoA), X-phosphate, in situ, and were used as recipients in experiments on TnphoA mutagenesis. KMR transconjugates were obtained only for A. brasilense S27, 85% of them were also PhoA+. About 12% TnphoA mutants of A. brasilense S27 had reduces capacity to swarming and 3% of mutants neither swam...
