LDH — Lactuca sativa

Summary

LsLDH, encoded by the gene LSAT_V11C300101670 on lettuce chromosome 3, is a member of the L-lactate/malate dehydrogenase family and possesses L-lactate dehydrogenase (NAD+) and NAD-L-malate dehydrogenase activities. The gene is associated with pyruvate breakdown, lactate and malate metabolism, the TCA cycle, glyoxylate cycle, detoxification, embryogenesis, ABA signaling, and response to salt and abscisic acid. It is linked to traits including respiration rate, phosphorus uptake, chlorophyll content, and salt tolerance, as well as the phenotype of oxygen deficit response. Studies of related genes in other species connect the family to hypoxia tolerance and traits such as root length, plant height, fruit size, and stomatal resistance.
