A BACILLUS METHYLOTROPHICUS STRAIN AND METHOD OF USING THE STRAIN TO INCREASE DROUGHT RESISTANCE IN A PLANT

摘要

A method of increasing drought resistance of a plant, the method comprising applying a Bacillus methylotrophicus or a composition thereof (i) to the plant or to a part of the plant; and/or (ii) to an area around the plant or plant part, in an amount effective to produce an increased drought resistance in the plant as compared to the drought stress resistance of the plant in the absence of said application of Bacillus methylotrophicus or composition, is described. A biologically pure culture of a 1-aminocyclopropane-l-carboxylate (ACC) deaminase deficient Bacillus methylotrophicus bacterium strain, or a mutant thereof able to induce drought resistance in a plant are also described.
