ABSTRACT
The production of secondary metabolites in plants, is greatly increased under stress by suppressing plant growth, due to the extra allocation of fixed carbon for secondary metabolites production. Plants produce a large pool of diverse natural chemicals, i.e., secondary metabolites, which is regularly produced by plants for genetic adaptation, to protect plants from the changing environment or to develop resistant against infection. But under prolonged stress, the nutrient predominantly allocated for secondary metabolites production, reverts for maintenance of cell osmotic balance that is necessary for proper metabolic activity of plants. The inoculation of halo-tolerant bacteria in plants, alone or in groups can lead to tolerance of plants against adverse environmental conditions and also improve other nutrient availability, helping the plant to overcome stress by regulating secondary metabolite production. Autotrophic plants need minerals for their life cycle and adequate supply of mineral nutrients that are necessary for optimum plant growth.
