NLP1 — Medicago truncatula

Summary

MTR_5G099060 (NLP1) in barrel medic encodes a protein of the NLP family, characterized by RWP-RK, GAF, and PB1 domains, and possesses DNA-binding, transcription factor, and SUMO transferase activities. It is associated with nitrate response, nitrogen homeostasis, nitrate import, and nodulation, as well as lateral root and root development, organogenesis, and embryo development. The gene is linked to auxin and starch anabolism, energy homeostasis, sumoylation, and responses to nitrate starvation and abscisic acid. It localizes to the nucleus and cytoplasm. Associations with nitrate uptake, stomatal opening, abscisic acid sensitivity, flowering time, biomass production, and heat stress response have been noted. Studies of related genes in other species connect the NLP family to shoot fresh weight, biomass yield, and thermotolerance.
