NAM — Medicago truncatula

Summary

MTR_2G080010, designated MtNAM, encodes a NAC-domain transcription factor with DNA-binding and transcription coactivator activity, localised to the nucleus. In barrel medic, this gene is associated with compound leaf morphogenesis, seed morphogenesis, integument development, regulation of nitrogen utilisation, gibberellic acid homeostasis, salicylic acid-mediated signalling, hyperosmotic salinity response, and phloem transport. It is also linked to traits including seed set, shoot elongation, whole plant size, male sterility, pollen fertility, floral organ identity, leaf shape, anthocyanin content, drought tolerance, and salt tolerance. Phenotypic associations include lateral root growth, phloem development, nitrate assimilation, seed development, and flowering time. Studies of related genes in other species link the family to leaf development, chlorophyll degradation, plant height, male fertility, and xylem expansion.
