PAD3 — Camelina sativa

Summary

CsPAD3 (CSA03G055560) on Camelina sativa chromosome 3 encodes a cytochrome P450 family 71 protein with dihydrocamalexic acid decarboxylase, costunolide synthase, and 4-hydroxyphenylacetaldehyde oxime monooxygenase activities. The gene is associated with camalexin and indole phytoalexin biosynthesis, dhurrin and sesquiterpene biosynthesis, and regulation of systemic acquired resistance. It is linked to defense responses against fungi, bacteria, and insects, as well as responses to abscisic acid, fruit ripening, and thirst. Localization evidence places the product in the endoplasmic reticulum membrane and lumen, plasmodesmata, and extracellular space. Phenotype associations include resistance to Leptosphaeria maculans, Alternaria brassicicola, Botrytis cinerea, Phytophthora brassicae, downy mildew, powdery mildew, and clubroot, along with aphid resistance, hypersensitive response, phytoalexin production, and zinc stress tolerance.
