MDH — Brassica oleracea

Summary

BoMDH (BOLC102_C03P071490.1) on chromosome 3 of cabbage encodes a protein with NAD-L-malate dehydrogenase activity and an AAA chloroplast protein-transporting ATPase function, belonging to the lactate/malate dehydrogenase C-terminal domain family. The gene is associated with malate metabolism, the TCA cycle, the glyoxylate cycle, and carboxylic acid metabolism. It is linked to responses to desiccation, heat, cold, and light stimulus, as well as defence against bacteria, embryo development ending in seed dormancy, and regulation of DNA-templated transcription. Associations with chloroplast development, high temperature stress response, and salt tolerance have been noted. The encoded protein localises to the plastid stroma, chloroplast envelope, inner membrane, nucleoid, and stromule, as well as the Ycf2/FtsHi complex and mitochondrial lumen. Related genes in other species link the family to chloroplast development under heat stress.
