ACT1 — Brassica oleracea var. botrytis

Summary

BoACT1, encoded by the gene BOLND125_C08P013240.1 on cauliflower chromosome 8, is a glycerol-3-phosphate O-acyltransferase with lipid carrier activity and protein binding capability, belonging to the GPAT_N_sf and Plipid/glycerol_acylTrfase domain families. The product localises to the chloroplast envelope, stroma and plastid, and is associated with ER-to-chloroplast lipid transport, plastid membrane organisation, guard cell development, regeneration, translation initiation, and phosphatidylglycerol and CDP-diacylglycerol anabolism. BoACT1 has been connected to plastid and chloroplast development traits, as well as phenotypes including boron uptake, root hair elongation, plant growth and development, defense response, galactolipid synthesis, pollen development, altered fatty acid composition, reduced phosphatidylglycerol content, glycerol sensitivity, C6-aldehyde formation, disease resistance, plastid morphology, increased stromules in leaf mesophyll, lipid transfer, embryo viability, and stomatal responses to CO2 and light. Related genes in other species link the family to boron sensitivity, self-incompatibility, chlorophyll content, disease tolerance, and salt tolerance.
