Mechanism of plant growth promotion by rhizobacteria.
Plant growth results from interaction of roots and shoots with the environment. The environment for roots is the soil or planting medium which provide structural support as well as water and nutrients to the plant. Roots also support the growth and functions of a complex of microorganisms that can have a profound effect on the growth anti survival of plants. These microorganisms constitute rhiz...
متن کاملPlant Growth Promotion by Endophytic Bacteria in Nonnative Crop Hosts
Studies highlighting the colonization and plant growth-promoting ability of endophytic bacteria inoculated into nonnative plant hosts reviewed and presented in this chapter. Endophytic bacteria, especially those related to the genus Bacillus, Burkholderia, Enterobacter, Gluconacetobacter, Herbaspirillum, Paenibacillus, Pseudomonas have been reported to form endophytic colonies in roots and shoo...
متن کاملPlant growth promotion induced by phosphate solubilizing endophytic Pseudomonas isolates
The use of plant growth promoting bacterial inoculants as live microbial biofertilizers provides a promising alternative to chemical fertilizers and pesticides. Inorganic phosphate solubilization is one of the major mechanisms of plant growth promotion by plant associated bacteria. This involves bacteria releasing organic acids into the soil which solubilize the phosphate complexes converting t...
متن کاملEffect of Siderophore on Plant Growth Promotion
At present fertilizer has become essential to modern agriculture to feed the growing population. Though chemical fertilizers increase crop production; their overuse has hardened the soil, decreased fertility, strengthened pesticides, polluted air and water, and released greenhouse gases, thereby bringing hazards to human health and environment as well. Due to the adverse effect of chemical fert...
متن کاملPromotion of Plant Growth by Soil Bacteria That Regulate Plant Ethylene Levels
One of the central the mechanisms used by many soil bacteria to directly promote plant growth is the production of the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase. This enzyme facilitates plant growth as a consequence of the fact that it sequesters and cleaves plantproduced ACC (the immediate precursor of ethylene in plants), thereby lowering the level of ethylene in the plant. In ...
