The chemotactic properties of a number of Azospirillum brasilense natural strains have been studied. Azospirillum demonstrate the positive chemotactic reaction towards the organic acids salts but a poor reaction towards the presence of the attractants like hydrocarbons and aminoacids except for arabinose and glutamic acid. The series of Che- mutants deficient in general chemotaxis has been selected by introducing the transposon Tn5 into the cells of rifampicinresistant mutant strain Azospirillum brasilense 5T-2. The ability of the mutant cells to fast and solid adsorption on the roots of the sterile wheat sprouts is shown to be decreased 2-3 folds as compared with the one of the wild type strain. Chemotaxis is suggested to affect the adsorbtion ability of azospirillum and their associative properties. |
