PAD3 — Camelina sativa

Summary

CsPAD3 (CSA17G085570) on Camelina sativa chromosome 17 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 alkaloid anabolism, and sesquiterpene and phenylpropanoid biosynthetic processes. It is linked to defense responses against fungi, bacteria, and insects, as well as responses to wounding, abscisic acid, and thirst. Localization evidence connects the product to the endoplasmic reticulum membrane and lumen, plasmodesmata, and extracellular regions. The gene is associated with resistance to multiple pathogens including Leptosphaeria maculans, Alternaria brassicicola, downy mildew, powdery mildew, and clubroot, along with aphid resistance, hypersensitive response, phytoalexin production, and zinc stress tolerance.
