LDH — Asparagus officinalis

Summary

A4U43_C01F19660, symbol AoLDH, encodes an L-lactate dehydrogenase (EC 1.1.1.27) with NAD⁺-dependent L-lactate and malate dehydrogenase activities, belonging to the lactate/malate dehydrogenase superfamily. In asparagus, this gene is associated with pyruvate breakdown, lactate metabolism, fermentation, the TCA cycle, glyoxylate cycle, malate metabolism, bile acid metabolism and homeostasis, and is linked to response to abscisic acid. It localises to the cytosol, cytoplasm and plasmalemma. AoLDH is also associated with respiration rate and oxygen deficit response. Studies of related genes in other species link the family to traits including root length, root branching, plant height, chlorophyll content, fruit size, fructose and glucose content, phosphorus uptake, iron concentration, stomatal resistance, photochemical quenching, and hypoxia tolerance.
