The influence of Plant Growth Promoting Rhizobacteria (PGPR) on the reduction of abiotic stresses in crops
Journal Title: Extreme Life, Biospeology & Astrobiology - International Journal of the Bioflux Society - Year 2011, Vol 3, Issue 2
Abstract
Plants are always subjected to biotic and abiotic stresses in the environment which have influences on the growth and development of the plants. Beneficial free-living soil bacteria are usually referred as Plant-Growth Promoting Rhizobacteria or PGPR. Different plant growth-promoting Rhizosphere bacteria, including associative bacteria such as: Azospirillum, Bacillus, Pseudomonas and Enterobacter group have been used for their beneficial influences on plants. Typically, PGPRs are associated with plants root and augment plant productivity and immunity; however, recent works showed that PGPRs not have just induced the systemic tolerance to abiotic stress such as salt and drought, but also they have increased the nutrient uptake from soils, and as a result the hazardous accumulation of nitrates and phosphates in the agricultural soils can be reduced by usage of them.
