Transient Accumulation of Jasmonic Acid During the Synchronized Hypersensitive Cell Death in Tobacco mosaic virus-Infected Tobacco Leaves
Abstract
Jasmonic acid (JA) transiently accumulated during temperature-dependent synchronous necrotic lesion formation in Tobacco mosaic virus-infected tobacco leaves. The accumulation of JA was preceded by activation of a tobacco mitogen-activated protein kinase, WIPK, which functions upstream of JA in wound signal transduction pathways.
