Root-Microbe Communication through Protein Secretion*

Root-microbe communication through protein secretion.

Biotic interactions in the rhizosphere are biologically important, and although many of those interactions have been well studied, the role of secreted proteins in the cross-talk between microbes and roots has not been investigated. Here, protein secretion was studied during the communication between the roots of two plants (Medicago sativa and Arabidopsis thaliana) and the bacterial symbiont o...

Root-Microbe Interactions: the Importance of Protein Secretion

The interactions between plants and microbes have been widely studied using gene expression studies and small molecule exchange between organisms. For the most part, these studies have focused on aboveground interactions and fewer studies have examined these types of processes belowground. The purpose of this review is to summarize the current literature looking at the interactions between root...

Activation of inflammasome and protein secretion by endogenous danger and microbe-derived signals in human macrophages

Beyond the barrier: communication in the root through the endodermis.

The root endodermis is characterized by the Casparian strip and by the suberin lamellae, two hydrophobic barriers that restrict the free diffusion of molecules between the inner cell layers of the root and the outer environment. The presence of these barriers and the position of the endodermis between the inner and outer parts of the root require that communication between these two domains act...

How Auxin and Cytokinin Phytohormones Modulate Root Microbe Interactions

A large range of microorganisms can associate with plants, resulting in neutral, friendly or hostile interactions. The ability of plants to recognize compatible and incompatible microorganisms and to limit or promote their colonization is therefore crucial for their survival. Elaborated communication networks determine the degree of association between the host plant and the invading microorgan...
