MDH — Pisum sativum

Summary

PsMDH (PSAT4G028720) on garden pea chromosome 4LG4 encodes a malate dehydrogenase with NAD-L-malate dehydrogenase activity and is a member of the malate dehydrogenase type 1 family. The gene is associated with the TCA cycle, cellular respiration, oxidative phosphorylation, malate metabolism, and the glyoxylate cycle, as well as with starch and sucrose anabolism, fermentation, the pentose-phosphate shunt, and stomatal opening. It is linked to chloroplast organization, chloroplast stroma protein import, response to hydrogen peroxide, detoxification, and NO storage. Associations include photosynthetic rate, germination rate, chloroplast development, and high temperature stress response. The gene is also connected to thermomemory, heat tolerance, oxidative stress tolerance, plastid genome stability, and redox response. Related genes in other species link the family to chloroplast development under heat stress.
