MDH — Triticum turgidum subsp. durum

Summary

TRITD1BV1G191700, symbol TtMDH, encodes a malate dehydrogenase (EC 1.1.1.37) with NAD-L-malate dehydrogenase activity, belonging to the malate dehydrogenase type 1 family. In durum wheat chromosome 1B, this gene is associated with malate metabolism, the TCA cycle, glyoxylate cycle, and carboxylic acid metabolism. It is linked to chloroplast organization, stroma protein import, and localization to plastid stroma, chloroplast inner membrane, and envelope. The gene has been connected to responses to heat, cold, light stimulus, and defence against bacteria, as well as root development, embryo development, and syngamy. Associations with respiration rate, photosynthetic rate, chloroplast development, and high temperature stress response have been noted. Studies of related genes in other species link the family to thermotolerance, thermomemory, plastid genome stability, salt tolerance, and stress tolerance.
