ISOLATION AND CHARACTERIZATION OF PLANT GROWTH PROMOTING RHIZOBACTERIA (PGPR) FROM SOLANUMLYCOPERSICUMPLANTROOTS
Abstract
One of the most consumable vegetable after potato are tomatoes (solanum lycopersicum). Tomatoes are an important crop worldwide, used as an investigating model to study different disease resistant mechanisms with respect to genetic/molecular aspects, research in genetics, and fruit development. The total yield and productivity of the plant marks significant reduction worldwide, owing to biotic and abiotic stresses. One big reason of tomato being subjected to more stress conditions is that it serves host for nearly about 200 plant pathogens (fungi, bacteria, nematodes, viruses, and others) and other environmental factors. These factors are classified as biotic and abiotic stress sources. One of the most widespread and omnipresent fungus fusarium oxysporum lycopersici concerns threat to the tomato. PGPR deals with the word plant growth promoting rhizobacteria that are classified as beneficiary bacteria. They reside in the roots of the plant or the rhizosphere soil being closely related to the host plant roots. A wide range of plant growth promoting rhizobacteria (PGPR) associates with the roots of tomato plants. These bacteria keep the soil profuse in nutrients, restrains the pest infection without any environmental damage, creating eco-friendly agriculture era. PGPR are bacteria that enhances plant growth and protect plants from disease and pathogen attack through a wide variety of defense mechanisms. PGPR traits include biological nitrogen fixation, mineral solubilization (phosphate), ammonia production, indole production etc. these bacteria are isolated from the roots of tomato plant and tested for pgpr traits. Total 9 different isolates are classified on the basis of N2 fixation and mineral solubilization.
