“…For example, two PGPB viz., Pseudomonas sp. CK-NBRI-02 and B. marisflavi CK-NBRI-03 having IAA and ACC deaminase-producing abilities besides other PGP traits, promoted plant growth and alleviated stress tolerance through their ability to metabolize methylglyoxal (MG), a cytotoxin generated as a consequence of stress in plants (Kaur et al, 2021). This suggested the role of MG tolerance by growth-promoting bacteria as a beneficial trait be considered when considering microbe-mediated stress mitigation in plants (Kaur et al, 2021).…”

Plant rhizo-microbiome comprises complex microbial communities that colonize at the interphase of plant roots and soil. Plant growth-promoting rhizobacteria (PGPR) in the rhizosphere provide important ecosystem services ranging from the release of essential nutrients for enhancing soil quality and improving plant health to imparting protection to plants against rising biotic and abiotic stresses. Hence, PGPR serve as restoring agents to rejuvenate soil health and mediate plant fitness in the facet of changing climate. Though it is evident that nutrient availability in soil is managed through inter-linked mechanisms, how PGPR expedite these processes remain less recognized. Promising results of PGPR inoculation on plant growth are continually reported in controlled environmental conditions, however, their field application often fails due to competition with native microbiota and low colonization efficiency in roots. The development of highly efficient and smart bacterial synthetic communities by integrating bacterial ecological and genetic features provides better opportunities for successful inoculant formulations. This review provides an overview of the interplay between nutrient availability and disease suppression governed by rhizobacteria in soil followed by the role of synthetic bacterial communities in developing efficient microbial inoculants. Moreover, an outlook on the beneficial activities of rhizobacteria in modifying soil characteristics to sustainably boost agroecosystem functioning is also provided.

“…In another study, the authors analysed the genomes of two potential growth‐promoting microbes, viz., Pseudomonas sp. CK‐NBRI‐02 (P2) and Bacillus marisflavi CK‐NBRI‐03 (P3) and found that they differ in their ability to metabolize methylglyoxal (MG), a ubiquitous cytotoxin regarded as general consequence of stress in plants (Kaur et al ., 2021). MG‐tolerant P2 was better able to sustain plant growth under dicarbonyl stress.…”
