“…An increase in temperature by 0.1 °C and a decrease in rainfall by ~ 31% reduced the Chickpea yield by ~ 40 kg ha −1 in the Bundelkhand region 4 . Development of drought-tolerant varieties, shifting the sowing time and resource management practices are some of the strategies to manage drought stress in chickpea 5 . However, the majority of these alternatives are cost-intensive and are beyond the reach of resource-poorfarmers.…”

In the present study, ten (10) selected bacteria isolated from chasmophytic wild Chenopodium were evaluated for alleviation of drought stress in chickpea. All the bacterial cultures were potential P, K and Zn solubilizer. About 50% of the bacteria could produce Indole-3-acetic acid (IAA) and 1-aminocyclopropane-1-carboxylate (ACC) deaminase. The bacteria showed wide range of tolerance towards pH, salinity, temperature and osmotic stress. Bacillus paralicheniformis L38, Pseudomonas sp. LN75, Enterobacter hormachei subsp. xiangfengensis LJ89, B. paramycoides L17 and Micrococcus luteus LA9 significantly improved growth and nutrient (N, P, K, Fe and Zn) content in chickpea under water stress during a green house experiment conducted following a completely randomized design (CRD). Application of Microbacterium imperiale LJ10, B. stercoris LN74, Pseudomonas sp. LN75, B. paralicheniformis L38 and E. hormachei subsp. xiangfengensis LJ89 reduced the antioxidant enzymes under water stress. During field experiments conducted following randomized block design (RBD), all the bacterial inoculations improved chickpea yield under water stress. Highest yield (1363 kg ha−1) was obtained in plants inoculated with Pseudomonas sp. LN75. Pseudomonas sp. LN75, B. paralicheniformis L38 and E. hormachei subsp. xiangfengensis LJ89 have potential as microbial stimulants to alleviate the water stress in chickpea. To the best of our knowledge this is the first report of using chasmophyte associated bacteria for alleviation of water stress in a crop plant.

Soil salinization is a critical global issue threatening agricultural productivity and significantly reducing the availability of arable land. Effective mitigation and recovery strategies are vital for sustaining food production, especially in the context of climate change. Halophytic plants, such as Atriplex nummularia, have shown potential for remediating saline soils, but their application remains limited. An alternative approach involves leveraging microorganisms adapted to saline environments to enhance plant stress tolerance. In this study, we investigated the microbiome of A. nummularia under saline and non-saline irrigation conditions to identify extremophilic microorganisms that promote salt stress tolerance. Through 16S rRNA analysis, we identified members of the genus Haladaptatus exclusively in the rhizosphere of salt-irrigated plants. These microorganisms were isolated and inoculated into maize crop systems to evaluate their ability to confer salt tolerance. Our results demonstrate that Haladaptatus strains significantly enhance salinity tolerance in maize, with a marked increase in the relative abundance of archaeal 16S rRNA in soils as NaCl irrigation levels rise. This study provides the first evidence that Haladaptatus, an archaeon isolated from the rhizosphere of a halophyte, can significantly enhance salt tolerance in an agriculturally important crop. These findings suggest a promising biotechnological application for improving crop resilience in saline environments, offering a sustainable strategy for addressing soil salinization and securing food production in the context of global climate challenges.
