Abstract:Nitrogen (N) is an essential macronutrient and a key cellular messenger. Plants have evolved refined molecular systems to sense the cellular nitrogen status. Exemplified by the root nodule symbiosis between legumes and symbiotic rhizobia, where external nitrate availability inhibits the interaction. However, nitrate also functions as a metabolic messenger, resulting in nitrate signaling cascades which intensively cross-talk with other physiological pathways. NIN (NODULE INCEPTION)-LIKE PROTEINS (NLPs) are key … Show more
