GPDHC1 — Brassica napus

Summary

BnGPDHC1, located on chromosome A03 of oilseed rape (Brassica napus), encodes a glycerol-3-phosphate dehydrogenase [NAD(P)+] with NAD binding and protein homodimerization activities, belonging to the G3P_DH_NAD-dep domain family. This gene is associated with glycerol-3-phosphate breakdown, lipid metabolism, fatty acid anabolism, triglyceride anabolism, and the TCA cycle, as well as with seed maturation, flowering time, and plant growth and development traits. It has been linked to oxidative stress response, abscisic acid sensitivity, and salt tolerance, and to phenotypes including reactive oxygen species accumulation, redox homeostasis, and NADH/NAD+ ratio. The gene product localizes to the cytosol, cytoplasm, and nucleus. Related genes in other species link the family to drought tolerance, altered germination under ABA and salt, and earlier flowering initiation.
