Plant growth promoting rhizobacteria (PGPR) and their eco-friendly strategies for plant growth regulation: a review

As a natural engineer, Plant Growth Promoting Rhizobacteria (PGPR) play an important role in increasing plant growth, yield and enhancing tolerance to stressful conditions. These beneficial bacteria take up their position the rhizosphere, around plants’ root tissues. They may be in, or on host tissues help provide nutrients plants. For sustainable agriculture, PGPR transmit extensive assistance ecosystem management, soil structure maintenance, stress management morphology physiology modulation environmentally friendly manner. Plant- interactions also stimulate nutrient acquisition accumulation, improve performance enhance abiotic biotic stresses. Beside these, are good biofertilizers safe for our environment. Nanotechnological advances with applications today increase impact of agriculture. Undoubtedly, concept is intimately involved horticulture, forestry they too enough establish vibrant In this review we have focused versatility PGPR-their aimed address some future prospects as eco-friendly tool growth regulation.
