Feed Your Friends: Do Plant Exudates Shape the Root Microbiome?


Sasse, Joelle; Martinoia, Enrico; Northen, Trent (2018). Feed Your Friends: Do Plant Exudates Shape the Root Microbiome? Trends in Plant Science, 23(1):25-41.

Abstract

Plant health in natural environments depends on interactions with complex and dynamic communities comprising macro- and microorganisms. While many studies have provided insights into the composition of rhizosphere microbiomes (rhizobiomes), little is known about whether plants shape their rhizobiomes. Here, we discuss physiological factors of plants that may govern plant-microbe interactions, focusing on root physiology and the role of root exudates. Given that only a few plant transport proteins are known to be involved in root metabolite export, we suggest novel families putatively involved in this process. Finally, building off of the features discussed in this review, and in analogy to well-known symbioses, we elaborate on a possible sequence of events governing rhizobiome assembly.
