The application of plant growth-promoting bacteria (PGPB) is vital for sustainable agriculture with continuous world population growth and an increase in soil salinity. Salinity is one of the severe abiotic stresses which lessens the productivity of agricultural lands. Plant growth-promoting bacteria are key players in solving this problem and can mitigate salinity stress. The highest of reported halotolerant Plant growth-promoting bacteria belonged to Firmicutes (approximately 50%), Proteobacteria (40%), and Actinobacteria (10%), respectively. The most dominant genera of halotolerant plant growth-promoting bacteria are Bacillus and Pseudomonas. Currently, the identification of new plant growth-promoting bacteria with special beneficial properties is increasingly needed. Moreover, for the effective use of plant growth-promoting bacteria in agriculture, the unknown molecular aspects of their function and interaction with plants must be defined. Omics and meta-omics studies can unreveal these unknown genes and pathways. However, more accurate omics studies need a detailed understanding of so far known molecular mechanisms of plant stress protection by plant growth-promoting bacteria. In this review, the molecular basis of salinity stress mitigation by plant growth-promoting bacteria is presented, the identified genes in the genomes of 20 halotolerant plant growth-promoting bacteria are assessed, and the prevalence of their involved genes is highlighted. The genes related to the synthesis of indole acetic acid (IAA) (70%), siderophores (60%), osmoprotectants (80%), chaperons (40%), 1-aminocyclopropane-1-carboxylate (ACC) deaminase (50%), and antioxidants (50%), phosphate solubilization (60%), and ion homeostasis (80%) were the most common detected genes in the genomes of evaluated halotolerant plant growth-promoting and salinity stress-alleviating bacteria. The most prevalent genes can be applied as candidates for designing molecular markers for screening of new halotolerant plant growth-promoting bacteria.

“…These bacteria have been investigated at the genetic level, leading to the identification of a large number of genes associated with halotolerance. These include groES and groEL (Patel et al, 2018), dnaJK, htpGX, grpE, clpB, clpX, andclpE (Yu et al, 2021), dnaK and dnaJ (Zhichang et al, 2010), groL, groS, and hspQ (Xia et al, 2023), ibpA, clpXP, and ibpB (Horváth et al, 2008, clpC (Chao et al, 2005), htpX (Liu et al, 2016), AtTPK3 (Carraretto, 2013), mrpABCDEFG (Suarez et al, 2019), kdp operon (Liu et al, 2016), MRP (Cui et al, 2020b), czcD and czcR (Asaf et al, 2020), copD and rcnA (Girma et al, 2020), and yjbQ (Gilhar et al, 2022). During high salinity conditions, the ion homeostasis of plants is mainly disturbed due to the inward movement of Na+ ions and outward movement of K+ ions (Demidchik et al, 2002;Mäser et al, 2002;Khan et al, 2020).…”

Soil salinity stress is a detrimental factor in crops production. Conventional methods of soil management and reclamation have been proved useless. On the contrary, exploiting the inherent genes and mechanisms of halotolerant bacteria can bring revolution in agriculture. Present study was designed to characterize ATPase dependent protein complexes kdpFABC and kdpDE in a salt tolerant bacterium Alcaligenes xylosoxydans. This complex enables plants to endure the saline environmental conditions through enhancing the K+ ions influx. For characterization, protein sequences of three isoforms of kdpA, four of kdpB, two of kdpC and one of kdpE were retrieved from Uniprot database. These were analyzed via ProtParam tool, AlphaFold protein database and HDOCK server. Highest affinity for ATP molecule was observed in kdpB confirming its reported function of ATP hydrolysis. All documented proteins were found polar (except kdpE), alkaline (except one isoform of each kdpA and kdpB), thermostable, to exhibit complex 3D structure (except for kdpC and E) and in vitro stability. These properties of subunit proteins can be exploited to engineer the complex and produce osmotolerant transgenic plants
