LDH — Cucumis sativus

Summary

CsLDH (CSA_5G161920) encodes an L-lactate dehydrogenase (EC 1.1.1.27) with L-lactate dehydrogenase (NAD+) activity and NAD-L-malate dehydrogenase activity, belonging to the lactate/malate dehydrogenase superfamily. In cucumber, this gene is associated with anaerobic respiration, ethanol fermentation, pyruvate breakdown, lactate metabolism, the TCA cycle, and response to abscisic acid. It is linked to seed germination, embryogenesis, cell death, and nitrogen fixation. The encoded protein localises to the cytosol, cytoplasm, and plasmalemma. CsLDH has been connected to root fresh weight, root length, root number, lateral root number, respiration rate, and oxygen deficit response. Studies of related genes in other species link the LDH family to hypoxia tolerance, fruit size, plant height, chlorophyll content, and phosphorus uptake.
