ACL — Sorghum bicolor

Summary

SbACL (SORBI_3003G184900) on sorghum chromosome 3 encodes a member of the MES/HNL family with AB hydrolase fold, exhibiting carboxylesterase, lipase, and specific MESA, MeJA, and MeIAA esterase activities. The gene is associated with metabolism of jasmonic acid, salicylic acid, nicotinate, dhurrin, and oxylipins, as well as responses to water, cold, UV-B, hypoxia, and fungal defence. It is linked to systemic acquired resistance, innate immunity, and embryo development ending in seed dormancy. The product localises to the vacuole, cytosol, and nucleus. Associations with seed germination, NAD biosynthesis, and nicotinate transport have been noted. Studies of related genes in other species link the family to methylesterase activity and triterpene, sterol, and anthocyanin accumulation.
