MDH1 — Pisum sativum

Summary

PSAT6G173040 (MDH1, PsNADP-MDH) on garden pea chromosome 6LG2 encodes a protein with L-malate dehydrogenase (NADP+) activity and NAD-L-malate dehydrogenase activity, and belongs to the malate dehydrogenase NADP-dependent plant family. It localises to the thylakoid, chloroplast stroma, envelope, plastid, mitochondria, apoplast, plasmalemma, and cytoplasm. This gene is associated with oxaloacetate and malate metabolism, the TCA cycle, cellular respiration, oxidative phosphorylation, redox signal response, NAD metabolism, sucrose and starch anabolism, stomatal opening, regeneration, NO storage, and proteolysis. It has been linked to photosynthetic rate, high light response, disease resistance, and cold tolerance. Related genes in other species link the family to chloroplast malate metabolism, redox homeostasis, quantum yield, transpiration rate, stomatal resistance, low temperature stress response, disease tolerance, and photochemical quenching.
