Up-regulated expression of lipoxygenase and divinyl ether synthase genes in pepper leaves inoculated with Tobamoviruses
To evaluate the importance of the oxylipin pathway in plant defense against viruses we
studied the induction of this pathway in a compatible and an incompatible virus–pepper
interaction. Obuda pepper virus (ObPV) inoculation led to the appearance of hypersensitive
necrotic lesions (incompatible interaction), to a marked induction of lipoxygenase (LOX)
enzyme activity, and to elevated transcription of three LOX genes in leaves of the pepper
cultivar TL 1791 harbouring the L3 resistance gene. In the same pepper cultivar Pepper mild …
