Understanding Rhizosphere Through Metatranscriptomic Approaches

The rhizosphere is a closely proximate area where plant roots and PGPR live together and produce various organic molecules, which boost plant growth and immunity. Metatranscriptomics is the best technique to study unexplored or unidentified microbes that help plants in terms of growth and also elicit induced systemic resistance against various plant pathogens. Metatranscriptomics provides direct access to the microbial community, which is not culturable on growth media. We have provided a holistic view in this chapter about rhizosphere, types of microbes which live in the rhizosphere, and how they affect plant health. We have discussed techniques that are used to study metatranscriptomic and bioinformatic tools to interpret the most valuable knowledge from sequencing data.
