The Hidden Chemical Cross-Talk Between Roots and Microbes: A Proteomic Approach

Abstract

Our earlier publications have indicated the importance of protein secretion in the interaction between roots and microbes [1]. In this review, we highlight the more recent discoveries on proteins in the rhizosphere and how they are used during plant-microbe communication. In addition, we include a survey of novel approaches to the study of the rhizosphere, the dynamics and trends of proteomics in this decade and new opportunities to focus proteomic studies. Therefore, the purpose of this review is to summarize the current literature looking at the interactions between roots and soil microbes, with an emphasis on the exchange of proteins between organisms.
