GPAT6 — Brassica napus

Summary

BnGPAT6 (GPAT6) on chromosome A04 of oilseed rape (Brassica napus) encodes a protein with glycerol-3-phosphate 2-O-acyltransferase activity, glycerol-3-phosphate O-acyltransferase activity, and phosphatase activity, belonging to the HAD_RAM2/GPAT1-8 family. The gene is associated with glycerolipid anabolism, diacylglycerol anabolism, galactolipid anabolism, cutin anabolism, lipid storage, fatty acid metabolism, embryogenesis, and response to water. It has been linked to membrane and mitochondrial localisation, and to traits including net photosynthetic rate, transpiration rate, stomatal resistance, and drought tolerance. Phenotypic associations include cuticle organization, root suberization, seed production, tapetum development, pollen tube elongation, and stamen filament elongation. Studies of related genes in other species connect the family to stamen length, germination rate, and pollen germination.
