TLDR
Mechanisms of PGPR in producing tolerate plants under salt stress and how to improve the plant–microbe interactions in future for increasing agricultural productivity to feed all of the world’s people are discussed.Abstract:
Salinity of water and soil are of the most important factors limiting the production of crops. Moreover, with the increasing population of the planet and saline fields worldwide there is no choice but to use saline soil and water in the near future. Therefore, to increase plant growth under saline stress condition, provision of sustainable and environmentally friendly management for the use of saline water and soil resources is necessary. The development of saline resistant plants is a potent approach to solve this problem. Generally, soil salinity negatively affects the plant growth through ion toxicity, oxidative stress, osmotic stress and ethylene generation. In recent years, scientists through genetic engineering techniques, which are based on molecular and physiological characteristics of plants, have made salt tolerance plants. However, the validation of the present technique is restricted to laboratory condition and it is not easily applied in the agronomy research under field environment. Another option would be to isolate and utilize salinity resistant microorganisms from the rhizosphere of halophyte plants, namely plant growth-promoting rhizobacteria (PGPR). The mechanisms of these bacteria includes; ACC-deaminase and exopolysachared production, osmolite accumulation, antioxidant system activation, ion hemostasis and etc. In this review, we will discuss mechanisms of PGPR in producing tolerate plants under salt stress and how to improve the plant–microbe interactions in future for increasing agricultural productivity to feed all of the world’s people.read more

TL;DR: This work suggests that equally important in a wide range of conditions are processes involving the management of Na(+) movements within the plant, and requires more knowledge of cell-specific transport processes and the consequences of manipulation of transporters and signalling elements in specific cell types.
