Defense gene induction in tobacco by nitric oxide, cyclic GMP, and cyclic ADP-ribose.

Jürgen Durner, David Wendehenne, D. F. Klessig
Proceedings of the National Academy of Sciences…
1998

Reactive oxygen species are believed to perform multiple roles during plant defense responses to microbial attack, acting in the initial defense and possibly as cellular signaling molecules. In… (More)

Active oxygen species in the induction of plant systemic acquired resistance by salicylic acid.

A complementary DNA encoding a salicylic acid (SA)-binding protein has been cloned. Its properties suggest involvement in SA-mediated induction of systemic acquired resistance (SAR) in plants. The… (More)

A mutation in Arabidopsis that leads to constitutive expression of systemic acquired resistance.

Scott A. Bowling, Amy Guo, H. Cao, A. S. Gordon, D. F. Klessig, X. Dong
The Plant cell
1994

Systemic acquired resistance (SAR) is a nonspecific defense response in plants that is associated with an increase in the endogenous level of salicylic acid (SA) and elevated expression of… (More)

Salicylic Acid: a likely endogenous signal in the resistance response of tobacco to viral infection.

Jocelyn E. Malamy, J. P. Carr, D. F. Klessig, Ilya Raskin
Science
1990

Some cultivars of tobacco are resistant to tobacco mosaic virus (TMV) and synthesize pathogenesis-related (PR) proteins upon infection. In a search for the signal or signals that induce resistance or… (More)

The cpr5 mutant of Arabidopsis expresses both NPR1-dependent and NPR1-independent resistance.

Scott A. Bowling, J. D. Clarke, Y. Liu, D. F. Klessig, X. Dong
The Plant cell
1997

The cpr5 mutant was identified from a screen for constitutive expression of systemic acquired resistance (SAR). This single recessive mutation also leads to spontaneous expression of chlorotic… (More)

Ancient signals: comparative genomics of plant MAPK and MAPKK gene families.

Louis-Philippe Hamel, Marie-Claude Nicole, +16 authors Brian Ellis
Trends in plant science
2006

MAPK signal transduction modules play crucial roles in regulating many biological processes in plants, and their components are encoded by highly conserved genes. The recent availability of genome… (More)

Salicylic acid is a modulator of tobacco and mammalian catalases.

Jürgen Durner, D. F. Klessig
The Journal of biological chemistry
1996

Salicylic acid (SA) plays a key role in the establishment of resistance to microbial pathogens in many plants. The discovery that SA inhibits catalase from tobacco led us to suggest that H2O2 acts as… (More)

MAPK cascades in plant defense signaling.

Steven Zhang, D. F. Klessig
Trends in plant science
2001

The Arabidopsis genome encodes approximately 20 different mitogen-activated protein kinases (MAPKs) that are likely to be involved in growth, development and responses to endogenous and environmental… (More)

Resistance to Pseudomonas syringae conferred by an Arabidopsis thaliana coronatine-insensitive (coi1) mutation occurs through two distinct mechanisms.

Andrew P. Kloek, Michelle L. Verbsky, +4 authors Barbara N Kunkel
The Plant journal : for cell and molecular…
2001

A new allele of the coronatine-insensitive locus (COI1) was isolated in a screen for Arabidopsis thaliana mutants with enhanced resistance to the bacterial pathogen Pseudomonas syringae. This mutant,… (More)

Salicylic acid activates a 48-kD MAP kinase in tobacco.

S Zhang, D. F. Klessig
The Plant cell
1997

The involvement of phosphorylation/dephosphorylation in the salicylic acid (SA) signal transduction pathway leading to pathogenesis-related gene induction has previously been demonstrated using… (More)
