MMDH — Medicago truncatula

Summary

MTR_8G463760 (MMDH, MtMMDH1) on barrel medic chromosome 8 encodes a malate dehydrogenase family protein with NAD-L-malate dehydrogenase activity, copper binding, ATP hydrolase activity, and protein binding. It is associated with malate metabolism, the TCA cycle, glyoxylate cycle, fermentation, nitrogen fixation, cell wall modification, meristem growth, root cap development, phyllome development, and male and female gamete generation. The gene is linked to respiration rate, photosynthetic rate, glucose and carbohydrate content, seed biomass, seed viability, germination rate, post-germination growth, seed longevity, leaf respiration, cadmium tolerance, cold acclimation, redox homeostasis, programmed cell death, disease tolerance, herbicide sensitivity, zinc sensitivity, root and meristem development, inflorescence morphology, and plant growth. It localizes to mitochondria, cytosol, plasmalemma, apoplast, plant-type cell wall, and proteasome. Related genes in other species link the family to photorespiration, metabolic flexibility, and zinc deficiency tolerance.
