PAD3 — Camelina sativa

Summary

CsPAD3 (CSA17G085600) on Camelina sativa chromosome 17 encodes a cytochrome P450 family 71 protein with dihydrocamalexic acid decarboxylase, costunolide 3beta-hydroxylase, parthenolide 3beta-hydroxylase, and 4-hydroxyphenylacetaldehyde oxime monooxygenase activities. The gene is associated with indole phytoalexin, camalexin, dhurrin, sesquiterpene, terpenoid, and alkaloid biosynthesis, as well as regulation of systemic acquired resistance. It is linked to defence responses against fungi, bacteria, and insects, including aphid resistance, downy mildew resistance, powdery mildew resistance, clubroot resistance, and resistance to Leptosphaeria maculans, Alternaria brassicicola, Botrytis cinerea, and Phytophthora brassicae. Additional associations include fruit ripening, response to abscisic acid, zinc stress tolerance, and hypersensitive response. The protein localises to the endoplasmic reticulum, plasmodesmata, and extracellular space.
