In natural ecosystems, plant health is mainly dependent on interactions with diverse and dynamic soil microbial communities. The microbial communities particularly those associated with nitrogen (N) cycling pathway inhabiting in rice field ecosystem have been described previously. Although, little is known about the taxonomic microbial players involved with dissimilatory nitrate reduction to ammonium (DNRA), a short-circuit N retention pathway in terrestrial N cycle. Therefore, we have to focus on how rice plants shape DNRA bacteria and how they alter over the course of several rice growth stages. Besides, we also shed lights on rice root physiology and the role of root exudates to address plant physiological aspects that may influence plant-microbe interactions.
