MDH — Pisum sativum

Summary

PSAT1G092720 (symbol MDH, also known as PsMDH) encodes a protein with NAD-L-malate dehydrogenase activity and an AAA chloroplast protein-transporting ATPase function, belonging to the lactate dehydrogenase/glycoside hydrolase family 4 C domain. In garden pea (Pisum sativum) on chromosome 1LG6, this gene is associated with the TCA cycle, glyoxylate cycle, oxidative phosphorylation, cellular respiration, fermentation, and the pentose-phosphate shunt. It is associated with chloroplast organization, chloroplast stroma protein import, and localization to the plastid stroma, chloroplast envelope, and inner membrane. Associations extend to photosynthetic rate, germination rate, chloroplast development, and responses to high temperature stress, hydrogen peroxide, and oxidative stress. The gene is also associated with thermomemory, heat tolerance, and plastid genome stability. Related genes in other species link the family to chloroplast development under heat stress.
