|a Symbiosis between legumes and rhizobia is a basic biological process behind sustainable agriculture. Still, in abiotic circumstances, such as drought, salt, and extreme temperatures, its efficiency is significantly reduced. This review highlights the molecular and physiological mechanisms that regulate root hair-rhizobia interactions, as root hairs serve as essential interfaces for microbial recognition, signal transduction, and infection thread growth. Root hair development in effective rhizobia colonization is influenced by auxin, ethylene, and environmental factors. Reacting to host flavonoids, which are detected by LysM receptor kinases (NFR1/NFR5), rhizobia produce nod factors causing calcium oscillations and corresponding transcriptional reprogramming of CCaMK, NSP1/2, and NIN. The changes in the cytoskeleton, the signaling of reactive oxygen species (ROS), and the remodeling of the cell wall all work together to change the shape of root hairs and make it easier for infection pockets to form. Rhizobia can keep symbiosis going even when abiotic stress happens by using adaptive mechanisms such as making exopolysaccharides, storing osmolytes, boosting antioxidant activity, and changing phytohormones signal. Combining multi-omics technologies, precision breeding, and microbial engineering will significantly enhance our understanding and improve root hair-mediated long-term symbiotic performance. This strategy promotes sustainable growth by reducing fertilizer usage, improving soil health, and ensuring food security in the face of changing climatic conditions
