LDH — Beta vulgaris subsp. vulgaris

Summary

BvLDH (BVRB_5G122810) on sugar beet chromosome Bvchr5_un.sca001 encodes an L-lactate dehydrogenase (EC 1.1.1.27) with NAD-L-malate dehydrogenase activity, belonging to the L-lactate/malate dehydrogenase family. The gene is associated with pyruvate breakdown, lactate metabolism, fermentation, the TCA cycle, the glyoxylate cycle, malate metabolism, glycogen anabolism, autotrophy, cell growth, cell death, and the apoptotic signaling pathway. It is linked to the response to abscisic acid, respiration rate, iron concentration, and oxygen deficit response. The encoded protein localizes to the mitochondrial lumen, cytosol, cytoplasm, and plasmalemma. Studies of related genes in other species connect the family to hypoxia tolerance and traits including root fresh weight, root length, lateral root number, root branching, plant height, fruit size, chlorophyll content, photochemical quenching, stomatal resistance, and phosphorus uptake.
