Journal ArticleDOI
Early signaling events induced by elicitors of plant defenses.
Angela Garcia-Brugger,Olivier Lamotte,Elodie Vandelle,Stéphane Bourque,David Lecourieux,Benoît Poinssot,David Wendehenne,Alain Pugin +7 more
TL;DR: Early signaling events that happen after elicitor perception are reviewed, including reversible protein phosphorylations, changes in the activities of plasma membrane proteins, variations in free calcium concentrations in cytosol and nucleus, and production of nitric oxide and active oxygen species.
Journal ArticleDOI
Nitric oxide production in tobacco leaf cells: a generalized stress response?
TL;DR: Nicotiana plumbaginifolia cell suspensions expressing the calcium reporter aequorin provided evidence that, under hyperosmotic stress, NO participates in the elevation of free Ca 2+ + + in the cytoplasm.
Journal ArticleDOI
Analysis of Nitric Oxide Signaling Functions in Tobacco Cells Challenged by the Elicitor Cryptogein
Olivier Lamotte,Kevin S. Gould,David Lecourieux,Anabelle Sequeira-Legrand,Angela Lebrun-Garcia,Jörg Durner,Alain Pugin,David Wendehenne +7 more
TL;DR: The data indicate that NO is intimately involved in the signal transduction processes leading to cryptogein-induced defense responses, and the signaling events that mediate NO production are investigated.
Journal ArticleDOI
Arabidopsis thaliana class-II TGA transcription factors are essential activators of jasmonic acid/ethylene-induced defense responses.
TL;DR: In this article, the same transcription factors are essential for the activation of jasmonic acid and ethylene (ET)-dependent defense mechanisms that counteract necrotrophic pathogens: the tga256 triple mutant is impaired in JA/ET-induced PDF1.2 and b-CHI expression, which correlates with a higher susceptibility against the necrotroph Botrytis cinerea.
Journal ArticleDOI
Nitric oxide in plants: the biosynthesis and cell signalling properties of a fascinating molecule.
TL;DR: A major advance in the understanding of NO functions in plants has been the identification of enzymes that catalyze NO synthesis and the role of nitrate reductase was the first enzymatic source of NO to be identified.
