First report on the microbial communities of the wild and planted raspberry rhizosphere – A statement on the taxa, processes and a new indicator of functional diversity

The considerable worldwide scale of raspberry crops merit thorough research, especially in the context of their root associated microorganisms. The current state of knowledge concerning microbial biodiversity occurring in the rhizosphere of such a desirable plant is rather fragmentary. Nevertheless,...
