Studying the interactions between Streptomyces bacteria and plant roots

In recent years it has become clear that actinomycete bacteria like Streptomyces species are not simply free-living soil bacteria. They also interact with plant roots and can colonise the rhizosphere and endosphere (inside the roots). This is fascinating because it helps us understand the natural ecology of these bacteria and their natural products - i.e. why they evolved, how they are regulated - and also because they may have uses as plant beneficial bacteria, e.g., by incorporating Streptomyces spores into seed coatings.
