LDH — Cucumis melo

Summary

MELO3C005539.2 (CmLDH) on melon chromosome 10 encodes a protein with L-lactate dehydrogenase (NAD+) activity and NAD-L-malate dehydrogenase activity. The protein contains lactate/malate dehydrogenase domains and is localised to the cytosol and plasmalemma. CmLDH is associated with pyruvate breakdown, lactate metabolism, anaerobic and aerobic respiration, the TCA cycle, glyoxylate cycle, malate metabolism, fruit development, and response to abscisic acid. It has been linked to respiration rate, root length, plant height, and oxygen deficit response. Studies of related genes in other species connect the LDH family to hypoxia tolerance, and to traits including fructose and glucose content, root fresh weight and branching, fruit size, chlorophyll content, and stomatal resistance.
