“…A corresponding enhancement in fresh weight and dry weight of both wheat and brinjal root and shoot biomass was observed in the bacterized seedlings compared to control plants under stress conditions. It has been reported that bacteria possessing abiotic stress tolerance along with PGP properties showed enhanced plant performance under various stresses (Patel et al 2017;Jinal et al 2019;Gopi et al 2020;Prittesh et al 2020;Chandwani et al 2022). Phytohormones produced by PGPB stimulate plant cell growth and division and enhance lateral root formation and absorptive surface area, thereby improving the ability of plants to acquire water (Sathya et al 2017;Jayakumar et al 2020).…”

Significance and Impact of the Study: Drought stress affects plant biomass and crop yield in arid and semiarid regions worldwide. The threat generated by drought stress must be addressed by improving plant growth under drought stress conditions. The application of osmotic stress-tolerant bacteria possessing plant growth-promoting properties is viable, eco-friendly and cost-effective. In this study, osmotic stress-tolerant bacteria improved the growth and biomass of wheat and brinjal under drought stress, and upregulated antioxidant enzymes. This study showed that microbes that mitigate drought stress may be used to enhance crop growth in arid and semiarid soils.

Plant-associated bacteria are essential partners in plant health and development. In addition to taking advantage of the rapid advances recently achieved in high-throughput sequencing approaches, studies on plant-microbiome interactions require experiments with culturable bacteria. A study on the rice root microbiome was recently initiated in Burkina Faso. As a follow up, the aim of the present study was to develop a collection of corresponding rice root-associated bacteria covering maximum diversity, to assess the diversity of the obtained isolates based on the culture medium used, and to describe the taxonomy, phenotype and abundance of selected isolates in the rice microbiome. More than 3,000 isolates were obtained using five culture media (TSA, NGN, NFb, PCAT, Baz). The 16S rRNA fragment sequencing of 1,013 selected isolates showed that our working collection covered four bacterial phyla (Proteobacteria, Firmicutes, Actinobacteria and Bacteroidetes) and represented 33% of the previously described diversity of the rice root microbiome at the order level. Phenotypic in vitro analysis of the plant growth promoting capacity of the isolates revealed an overall ammonium production and auxin biosynthesis capacity, while siderophore production and phosphate solubilisation were enriched in Burkholderia, Ralstonia, Acinetobacter and Pseudomonas species. Of 45 representative isolates screened for growth promotion on seedlings of two rice cultivars, five showed an ability to improve the growth of both cultivars, while five others were effective on only one cultivar. The best results were obtained with Pseudomonas taiwanensis ABIP 2315 and Azorhizobium caulinodans ABIP 1219, which increased seedling growth by 158% and 47%, respectively. Among the 14 best performing isolates, eight appeared to be abundant in the rice root microbiome dataset from previous study. The findings of this research contribute to the in vitro and in planta PGP capacities description of rice root-associated bacteria and their potential importance for plants by providing, for the first time, insight into their prevalence in the rice root microbiome.
