Immunofluorescence localization of levopimaradiene/abietadiene synthase in methyl jasmonate treated stems of Sitka spruce (Picea sitchensis) shows activation of diterpenoid biosynthesis in cortical and developing traumatic resin ducts

Methyl jasmonate-induced levopimaradiene/abietadiene synthase, responsible for diterpene biosynthesis in spruce, is localized to activated cortical resin duct (CRD) and nascent traumatic resin duct (TRD) epithelial cells.
