Abstract

The use of NGS technologies have allowed researchers to study host-microbe interactions at an unprecedent scale. These studies began with a huge interest in the study of human gut microbiome and other eukaryotic hosts. However, it has been realised the importance of studying plant-associated microorganisms, especially those inhabiting the rhizosphere, which is modulated by root exudates that selectively stimulate beneficial microorganisms. Thus, as these beneficial interactions remain poorly understood as well as the effects of root exudates in the recruitment of microorganisms, the main goal of this project is to identify, using metagenomic approaches, whether different wheat varieties are associated with distinct microbial partners and if these associations are linked to plant exudation profile and crop yield. The information and training will be very useful in the search for "good" microbial candidates that could improve plant fitness and act against some important wheat phytopathogens, contributing to the interpretation of results of ongoing experiments in Brazil.
