ACP — Sorghum bicolor

Summary

SORBI_3008G116400, also known as SbACP, encodes a protein with a chloroplastic ACP domain and phosphopantetheine binding and acyl carrier activities. In sorghum, this gene is associated with fatty acid, anthocyanin, and cuticle anabolism, phosphatidic acid metabolism, response to hormones and light stimulus, salinity response, and regulation of transport. The protein localizes to the chloroplast envelope and stroma, as well as the cytosol. Associations with leaf color, light response, chloroplast lipid biosynthesis and metabolism, fatty acid composition, lipid content, abiotic stress tolerance, salicylic acid content, and constitutive expression have been noted. Studies of related ACP genes in other species link the family to salt and drought tolerance, abscisic acid and phosphate starvation responses, systemic acquired resistance, photosynthetic efficiency, and leaf lipid content, while sequence similarity connections in other species extend to traits including seed weight, grain number, anthocyanin and starch content, and heat tolerance.
