SS — Asparagus officinalis

Summary

AoSS (A4U43_C03F10300) on asparagus chromosome 3 encodes a squalene synthase (EC 2.5.1.21), a member of the squalene/phytoene synthase family with squalene synthase activity. The gene is associated with isoprenoid, sterol, triterpenoid, saponin, and ether anabolism, as well as farnesyl diphosphate metabolism and the lipoxygenase pathway. It has been linked to responses to jasmonic acid, salicylate, ethylene, nitric oxide, hydrogen peroxide, vanadate, and molecules of fungal origin. The product localises to the endoplasmic reticulum membrane, mitochondria, and plasma membrane. Related genes in other species are linked to sterol, triterpene, and brassinosteroid biosynthesis, and to UV stress response. The gene is also associated with triterpenoid production.
