Streptomyces as a plant's best friend?

Here we discuss the advantages of the majority of this versatile and diverse group of microorganisms for plant health and growth as demonstrated by their contribution to disease-suppressive soils, their antifungal and antibacterial activities, their ability to produce volatile compounds and their capacity to enhance plant biomass. Although much is still to be discovered about the colonization strategies and molecular interactions between plant roots and these microorganisms, they are destined to become important players in the field of plant growth-promoting rhizobacteria for agriculture.
