Abstract

Plant growth promoting rhizobacteria (PGPR) are bacteria that inhabit the soil and are often isolated from the rhizosphere of several plant species. The effects of microrganisms on plant growth are broad, including beneficial effects in the control of plant pathogens in the soil, seedling emergence and growth of plants. The study of modes of action of rhizobacteria responsive increase in plant growth, has been the focus of several studies available in the literature, but has also been reported that rhizobacteria can interfere with plant tolerance to abiotic stresses and influence biochemichal characteristics. Water deficit during cultivation agriculture has been a major cause of frustration harvests in recent decades and actions designed to increase the tolerance of plants to emerge as great interest for agricultural research. In sustainable agricultural systems inoculation of bacteria may provide cross-protection against different stresses: biotic and abiotic factors. The inoculation of Bacillus subtilis in plant seeds, acting as PGPR, has provided positive results in several studies, describing how this bacterial species with great potential for use in agriculture. This project objective evaluate isolates of Bacillus subtilis to induce tolerance to water stress and production of antioxidant compounds in plants. Will assess the performance of bacterial isolates to promote plant growth in water deficit conditions, and changes in physiological parameters related to oxidative stress. The results of this study substantiate new lines of research into the use of rhizobacteria in agriculture seeking to minimize the deleterious effects of drought and increases in nutritional quality of food.
