Abstract

In the present era salinity stress becomes a huge obstacle for global agricultural productivity. It is reported that crop loss due to salinity alone is 20 to 50%. In the present review one denotes and preambles the significant role of plant growth promoting rhizobacteria (PGPR) as a green bioinoculant in mitigating salinity stress in spinach. Spinach is a salt-sensitive crop and salinity decreases spinach seedling germination, and root-elongation thereby lowering its productivity. The PGPR alleviates the detrimental effects of soil salinity in spinach by improving plant defense mechanisms. Such PGPR not only would increase the productivity of spinach but also of other crops as preamble here. This would lead to increased crop yield and hence meet the food demands of large population. The detrimental effects of soil salt stress in plants include nutrient uptake inhibition by interfering directly with ion transporters in the root plasma membrane (e.g. K+ selective ion channels) and by inhibiting root growth.
However, work on alleviation of detrimental effects of salinity is scarce and needs to be explored more. This review is just and attempt to draw the attention of such agriculturists and scientists to acknowledge this aspect of spinach and PGPR. This is a healthy relation of spinach and PGPR and hence PGPR can be a futuristic, potential bioinoculant for spinach to cope with abiotic stress viz, soil salinity stress.
