Streptomyces spp., a key genus in Actinobacteria, show promise in agriculture. They promote plant growth and biocontrol of pests, diseases, and weeds through the production of phytohormones, siderophores, enzymes, and other metabolites. Additionally, they enhance nutrient availability and alleviate abiotic stresses like salinity and drought, offering a sustainable, eco-friendly approach to improve crop productivity and reduce agrochemical use.
