MDH — Pisum sativum

Summary

PsMDH (PSAT4G051000) on garden pea chromosome 4LG4 encodes a malate dehydrogenase with NAD-L-malate dehydrogenase activity, belonging to the malate dehydrogenase type 1 family and containing lactate/malate dehydrogenase domains. The gene is associated with the TCA cycle, glyoxylate cycle, oxidative phosphorylation, cellular respiration, fermentation, and the pentose-phosphate shunt, as well as malate and carboxylic acid metabolism, and sucrose and starch anabolism. It is linked to chloroplast organization, stomatal opening, detoxification, response to hydrogen peroxide, and NO storage. Associations with photosynthetic rate, germination rate, chloroplast development, and high temperature stress response have been noted. The gene is also connected to thermomemory, plastid genome stability, heat and oxidative stress tolerance, and chaperone activity. Related genes in other species link the family to chloroplast development under heat stress.
