Nutrient cross-feeding in the microbial world

Nutrient cross-feeding in the microbial world | Biología | Scoop.it

The stability and function of a microbial community depends on nutritional interactions among community members such as the cross-feeding of essential small molecules synthesized by a subset of the population. In this review, we describe examples of microbe–microbe and microbe–host cofactor cross-feeding, a type of interaction that influences the forms of metabolism carried out within a community. Cofactor cross-feeding can contribute to both the health and nutrition of a host organism, the virulence and persistence of pathogens, and the composition and function of environmental communities. By examining the impact of shared cofactors on microbes from pure culture to natural communities, we stand to gain a better understanding of the interactions that link microbes together, which may ultimately be a key to developing strategies for manipulating microbial communities with human health, agricultural, and environmental implications.

Ectomycorrhizal (ECM) fungi establish a mutualistic association with tree roots. Root colonization involves the formation of an invasive hyphal network, known as a Hartig net, that encases the plant epidermal cells. Many of the details of the mechanism by which such an extensive network is established in the presence of a functional plant immune response — which includes the hormone jasmonic acid — are still unknown. A new study now provides the first mechanistic insights into the negative regulation of plant jasmonic acid signalling by an ECM fungus.
