An important abiotic stressor that hinders plant growth, nutrient uptake, and global agricultural productivity is soil salinity. Among the different strategies to overcome the issue of salinity in agriculture sector, plant growth-promoting rhizobacteria (PGPR) have gained recognition as promising beneficial microbes that can improve plants’ response to biotic and abiotic stressors. The salinity tolerance and traits that promote plant growth of eight PGPR strains (RT1, RT2, RT3, RT4, RT5, RT7, and RT12) were evaluated in this study. During screening, one strain, RT12, had the highest plant growth-promoting activity and salt tolerance in the group. The strain when subjected to NaCl stress showed quantitative ACC-deaminase activity, in the presence of NaCl at various concentrations, demonstrating extraordinary tolerance to salt stress by withstanding doses of up to 3M NaCl. In order to further investigate the effects of salt stress on Brassica juncea (mustard), RT12, which was identified as Pseudomonas putida using 16s RNA sequencing, was inoculated. Two salt treatments (100 and 150 mM) were applied to the mustard variety ‘Mingora’ in a greenhouse. The results revealed that through ACC utilization, PGPR directly induced plant growth in salt-stressed mustard plants by lowering excess ethylene production. All plant parameters were negatively impacted by an increase in NaCl concentration in uninoculated plants. However, P. putida RT12 inoculation enhanced all growth parameters, antioxidant production, total soluble sugar (TSS), total protein (TP), proline, relative water content (RWC), chlorophyll contents, and nutrient uptake in salt-treated plants. The inoculation with P. putida also caused a marked decline in Na+ uptake and an increase in K+ uptake in the shoot. By maintaining a greater K+/Na+ ratio in the tissues of RT12-inoculated plants compared to controls, this change in ion uptake helped to maintain nutritional balance of the plants. The findings suggest that inoculating plants with ACC deaminase-producing PGPR, such as P. putida RT12, may boost growth and stress resistance.

The symbiotic synergy between proteome shifts in plants and microbial colonization orchestrates adaptive responses. This thorough review delves into the less explored domain of proteomic and metabolomic changes triggered by drought stress, shedding light on how they are influenced by interactions with microbiota. Notably, microbial mediation at the crossroads of hormone signaling, proteomic and metabolomic dynamics in drought adaptation emerges as a crucial focal point. Understanding the regulatory mechanisms that orchestrate these complex interactions offers a holistic view of the molecular foundation underlying a plant's ability to endure water scarcity. The insights gained from this exploration hold the potential to reshape agricultural practices and enhance drought‐tolerance through microbiota‐mediated mechanisms, supported by proteomic and metabolomic insights. As this review seamlessly integrates the latest developments in understanding drought stress responses, microbiota dynamics, proteomics and metabolomic, it reveals the interconnected molecular basis that underlies these aspects. Specifically, the review emphasizes the crucial role of microbial mediation at the crossroads of hormone signaling, proteomic and metabolomic dynamics during drought adaptation. This enhanced understanding of the intricate interactions among these components presents new opportunities for envisioning sustainable agricultural approaches in the face of the escalating challenges presented by intensifying drought scenarios.

“…Soil extract preservation included adding one drop of sodium hexametaphosphate in 25 ml extract to minimize the precipitation of salts. The NPK and Zn detection in soil samples adopted the procedure mentioned in the ICARDA manual (Tahir et al, 2022). Then, organic matter and carbon determination ran at the INIA-HUARAL to evaluate how much nutrients were available in the soil for quality checking.…”

The scarcity of nutrients and synthetic fertilizers reduced crop productivity, increasing production costs and prompting scientists to seek new technologies to ensure high-quality output. In this context, using cytokinins with organic fertilizers ensued to assess their effects on caigua (Cyclanthera pedata L.) production. For this purpose, land preparation for planting comprised two levels of cytokinins (100 and 150 ml, Anthesis Plus per 200 L of water) and organic compost at 10 t/ha, then spread across the land. Results showed that adding cytokinins and compost manure, alone and in combination, significantly improved the agronomic and physiological characteristics of caigua. However, the combined application of compost manure and cytokinins dramatically enriched the caigua plant length, diameter, fruits per plant, and fruit dry and fresh weight per plant up to 85.0%, 46.9%, 81.8%, 80.6%, and 83.2%, respectively, in comparison with the control treatment. Similarly, chlorophyll contents, quantum yield, photosynthetically active radiation, fluorescence yield, and electron transport reaction increased at 68.8%, 66.4%, 79.2%, 51.1%, and 74.0%, respectively, with combined application as compared with control. Furthermore, the co-addition of composting and cytokinins also upgraded the biochemical composition versus the control. The presented results suggested that applying a mixture of compost manure and cytokinins may help enhance caigua plant growth, yield, and quality and improve soil characteristics.
