PAD3 — Camelina sativa

Summary

CsPAD3 (CSA14G016090) on Camelina sativa chromosome 14 encodes a cytochrome P450 family 71 protein with dihydrocamalexic acid decarboxylase, 4-hydroxyphenylacetaldehyde oxime monooxygenase, and 4-hydroxyphenylacetonitrile hydroxylase activities. The gene is associated with camalexin, indole phytoalexin, dhurrin, alkaloid, and phenylpropanoid biosynthesis, as well as regulation of systemic acquired resistance. It is linked to defence responses against fungi, bacteria, insects, and wounding, and to responses to abscisic acid and fruit ripening. The protein localises to the endoplasmic reticulum membrane and lumen, plasmodesmata, and extracellular regions. CsPAD3 is associated with resistance to Leptosphaeria maculans, Alternaria brassicicola, Phytophthora brassicae, downy mildew, powdery mildew, and clubroot, as well as to aphid defence, zinc stress tolerance, and phytoalexin production.
