MDH — Phaseolus vulgaris

Summary

PHAVU_002G216800, designated PvMDH, encodes a malate dehydrogenase with NAD-L-malate dehydrogenase activity, belonging to the malate dehydrogenase type 1 family. In French bean (Phaseolus vulgaris) on chromosome 2, this gene is associated with the TCA cycle, glyoxylate cycle, malate metabolism, regulation of photorespiration, and regulation of fatty acid beta-oxidation. It is linked to photosynthetic rate, quantum yield, stomatal resistance, and seed coat color. The encoded protein localizes to multiple compartments including the microbody, mitochondrial lumen, chloroplast envelope, plastid, ER, and secretory vesicle. Studies of related genes in other species connect the family to carbohydrate content, transpiration rate, germination rate, seed dormancy, and stomatal opening.
