Plant Growth-Promoting Bacterial Life at High Salt Concentrations: Genetic Variability

  • Ritika Kapoor

Abiotic stresses are emerging environmental factors limiting agricultural productivity around the world. Among these stresses, salt stress is a serious threat affecting crop production especially in arid and semiarid regions of the world. Development of strategies to ameliorate deleterious effects of salt stress on plants has received considerable attention. In this scenario, the use of salt-tolerant plant growth-promoting microorganisms to enhance salinity resilience in crops is encouraged due to their vital interactions with crop plants. Bacteria are widely used to diminish deleterious impacts of high salinity on crop plants because they possess various direct and indirect plant growth-promoting characteristics. This chapter focuses on the effect of salt stress on plants, plant growth-promoting bacterial survival in saline conditions, and their mechanisms to mitigate salt stress at genetic level.
