Beneficial microorganisms have profound positive impacts on various human activities, including medicinal, pharmaceutical, and other biotechnological applications. This review provides an update about the potential of Streptomyces species as promising plant promoters because of their various roles as biofertilizers, biostimulators, biocontrol agents, and bioremediates. It also briefs the numerous mechanisms tackled by Streptomyces species, including the synthesis of plant growth regulators, siderophore production and secretion of the volatile compound to improve crop productivity. The percentage of increment in yield of different plants on inoculation with Streptomyces species is also outlined. Plant growth-promoting Streptomyces species are collectively Streptomyces highlighted as drivers for food security to satisfy global food demand.
Key words: plant-growth promotion, Streptomyces, plant yield, soil fertility.
