DHN — Medicago truncatula

Summary

MTR_6G084640 (MtDHN, also known as MtDHN3 or CAS31) on barrel medic chromosome 6 encodes a dehydrin, a member of the dehydrin cold-shock domain family. The gene is associated with macroautophagy and autophagy, nitrogen fixation, nodulation, cold acclimation, embryogenesis, jasmonic acid signaling, and responses to heat, cold, abscisic acid, and thirst. Its product localises to the cytosol and cytoplasm. MtDHN is associated with drought tolerance and salt tolerance. Studies of related genes in other species link the family to traits including leaf relative water content, root weight, transpiration rate, water use efficiency, germination rate, stomatal resistance, root length, and plant height.
