title: In vivo detection of tobacco mosaic virus-induced local and systemic oxidative burst by electron paramagnetic resonance spectroscopy.
abstract: This is the first demonstration that tobacco mosaic virus-induced oxidative stress in a necrotic host plant is signalled by an elevated level of monodehydroascorbate (MDA) radicals detected by electron paramagnetic resonance spectroscopy. Furthermore, systemic acquired resistance induced in remote leaves of Xanthi-nc tobacco is also associated with stimulated MDA signals indicative of a microoxidative burst.
