Metabolomics in the Rhizosphere: Tapping into Belowground Chemical Communication
Nicole M van Dam et al. Trends Plant Sci. 2016 Mar.
Abstract
The rhizosphere is densely populated with a variety of organisms. Interactions between roots and rhizosphere community members are mostly achieved via chemical communication. Root exudates contain an array of primary and secondary plant metabolites that can attract, deter, or kill belowground insect herbivores, nematodes, and microbes, and inhibit competing plants. Metabolomics of root exudates can potentially help us to better understand this chemical dialogue. The main limitations are the proper sampling of the exudate, the sensitivity of the metabolomics platforms, and the multivariate data analysis to identify causal relations. Novel technologies may help to generate a spatially explicit metabolome of the root and its exudates at a scale that is relevant for the rhizosphere community.
Keywords: allelopathy; mycorrhiza; plant–herbivore interactions; root exudates; secondary metabolites; volatiles.
