“…Such treatments hold potential for assisting crops in addressing the growing challenge of salinization in agricultural lands affected by factors such as irrigation or marine intrusion [36,37,40,41]. Furthermore, they present a viable approach for reclaiming lands impacted by gypsum accumulation due to evaporation amplified by climate change effects, including increased heat and drought [43,44]. The objective of this study was to pinpoint novel strain inducers of osmotic tolerance in severely stressed environments, including salt flats, salt marshes, and gypsum-rich areas.…”

Saline and gypsic soils impede or condition the establishment of farms in many regions worldwide. Stress caused by the accumulation of sodium or calcium ions in the soil drastically limits plant growth and is a limiting factor in the production of many crops. For this reason, saline and gypsic soils were preferentially exploited for mineral extraction. However, nowadays, they can be a source of new biotechnological tools to help in the osmotic stress to which some crops are exposed. In these environments, despite being traditionally characterized by their low biodiversity, we can find well-adapted microbiota that may be able to interact with plants to deal with different environmental stresses. These mechanisms may consist of a very important contribution to the development of new osmotic stress-dealing bioinoculants. The present study sought to elucidate the diversity of the cultivable population of such environments and use them as regulators of soil nutrients and stress-relieving symbionts in plants under osmotic stress. Among the candidate strains selected to cover more scenarios, we found that the strains Stutzerimonas stutzeri A38 and Bacillus pumilus A49 were able to increase root size under osmotic stress in Medicago sativa and Medicago polymorpha plants. Moreover, Peribacillus frigoritolerans A70 and Bacillus licheniformis A46 also enhanced the performance in M. polymorpha, showing interesting potential for a future use in wasteland use for production to livestock feeding or other relevant industries.

“…Table 2 displays the impacts of several microorganisms that promote plant development. By promoting nutrient cycling and preventing disease via the synthesis of antimicrobial substances and other metabolites, PGPRs may enhance the characteristics of soil (Chaudhary et al, 2021). Furthermore, PGPRs can promote plant growth by encouraging root and shoot expansion, which increases biomass and yield.…”

This review explores how plant growth-promoting rhizobacteria (PGPRs) and nanoparticles can improve the physicochemical traits of wheat plants and boost crop yields. Wheat is essential for the world's food supply, but its growth is impacted by factors such as soil quality and climate. The potential for enhancing crop productivity and soil quality with PGPRs is promising. They improve wheat plant photosynthesis, soil fertility, nutrient availability, and antioxidant activity. When nanoparticles and PGPRs are used together, physicochemical characteristics are improved due to their synergistic effects. These environmentally friendly techniques have the potential to encourage the sustainable production of wheat, reduce dependence on synthetic fertilizers and pesticides, and increase soil fertility. However, it is critical to address any possible health and environmental risks associated with their use. Overall, PGPRs and nanoparticles are viable options for increasing wheat crop production and sustainability.

Drought conditions pose significant challenges to sustainable agriculture and food security. Identifying microbial strains that can mitigate drought effects is crucial to enhance crop resilience and productivity. This study presents a comprehensive comparison of several machine learning models, including Random Forest, Decision Tree, XGBoost, Support Vector Machine (SVM), and Artificial Neural Network (ANN), to predict optimal microbial strains for this purpose. Models were assessed on multiple metrics, such as accuracy, standard deviation of results, gains, total computation time, and training time per 1000 rows of data. Notably, the Gradient Boosted Trees model outperformed others in accuracy but required extensive computational resources. This underscores the balance between accuracy and computational efficiency in machine learning applications. Leveraging machine learning for selecting microbial strains signifies a leap beyond traditional methods, offering improved efficiency and efficacy. These insights hold profound implications for agriculture, especially concerning drought mitigation, thus furthering the cause of sustainable agriculture and ensuring food security.
