PAD3 — Camelina sativa

Summary

CsPAD3 (CSA17G018450) on Camelina sativa chromosome 17 encodes a cytochrome P450 protein of the CYP71 family with dihydrocamalexic acid decarboxylase, costunolide synthase, and 4-hydroxyphenylacetaldehyde oxime monooxygenase activities. The gene is associated with the biosynthesis of camalexin and other indole phytoalexins, as well as dhurrin, sesquiterpenes, and alkaloids. It has been linked to defense responses against fungi, bacteria, and insects, including resistance to Leptosphaeria maculans, Alternaria brassicicola, powdery mildew, downy mildew, and clubroot. CsPAD3 is also connected to aphid resistance, hypersensitive response, systemic acquired resistance, fruit ripening, abscisic acid response, and zinc stress tolerance. The encoded protein localizes to the endoplasmic reticulum membrane and is also found in the extracellular space and plasmodesmata.
