ACL — Sorghum bicolor

Summary

SORBI_3003G417100 (SbACL) encodes a member of the MES/HNL family with AB hydrolase-1 domain, possessing carboxylesterase, lipase, and specific esterase activities toward polyneuridine-aldehyde, methyl salicylate, methyl jasmonate, and methyl indole-3-acetate. In sorghum, this gene is associated with metabolism of nicotinate, salicylic acid, jasmonic acid, dhurrin, indole alkaloids, 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 through seed dormancy. The protein localises to the vacuole, cytosol, and nucleus. Related genes in other species connect the family to methylesterase activity, triterpene and sterol accumulation, while sequence similarity links SbACL to root dry weight, pollen fertility, anthocyanin content, and seed growth traits.
