Emerging crops and plant growth-promoting bacteria (PGPB): a synergistic approach to climate-resilient agriculture

Abstract This review highlights the benefits of mutualistic plant–microbe interactions in enhancing the resilience of emergent crops and underlies the potential of these crops as valuable resources for exploring novel plant growth-promoting bacteria (PGPB). Emergent crops such as quinoa, amaranth, millet, lupins, hemp and desert truffles exhibit physiological and ecological traits that make them suitable for stress-prone environments. PGPB offer sustainable solutions to mitigate abiotic stress by improving nutrient availability, modulating phytohormone levels, enhancing root development and inducing systemic resistance.
