Abscisic Acid Inhibits Type 2C Protein Phosphatases via the PYR/PYL Family of START Proteins
Sang-Youl Park,Pauline Fung,Noriyuki Nishimura,Davin R. Jensen,Hiroaki Fujii,Yang Zhao,Shelley Lumba,Julia Santiago,Americo Rodrigues,Tsz-fung Freeman Chow,Simon E. Alfred,Dario Bonetta,Ruth R. Finkelstein,Nicholas J. Provart,Darrell Desveaux,Pedro L. Rodriguez,Peter McCourt,Jian-Kang Zhu,Julian I. Schroeder,Brian F. Volkman,Sean R. Cutler +20 more
TL;DR: PYR/PYLs are ABA receptors functioning at the apex of a negative regulatory pathway that controls ABA signaling by inhibiting PP2Cs, illustrating the power of the chemical genetic approach for sidestepping genetic redundancy.
Journal ArticleDOI
The Arabidopsis NPR1 Disease Resistance Protein Is a Novel Cofactor That Confers Redox Regulation of DNA Binding Activity to the Basic Domain/Leucine Zipper Transcription Factor TGA1
Charles Després,Charles Després,Catherine Chubak,Amanda Rochon,Rena Clark,Terry D. Bethune,Darrell Desveaux,Darrell Desveaux,Pierre R. Fobert +8 more
TL;DR: It is reported that although TGA1 does not interact with NPR1 in yeast two-hybrid assays, treatment with salicylic acid induces the interaction between these proteins in Arabidopsis leaves, and it is indicated that T GA1 relies on the oxidation state of Cys residues to mediate the interaction withNPR1.
Journal ArticleDOI
The roles of ABA in plant–pathogen interactions
TL;DR: This review presents examples demonstrating the importance of crosstalk between ABA and the key biotic stress phytohormone salicylic acid in determining the outcome of plant–pathogen interactions and discusses future directions for studies of ABA in plant immunity.
Journal ArticleDOI
The Pseudomonas syringae effector AvrRpt2 cleaves its C-terminally acylated target, RIN4, from Arabidopsis membranes to block RPM1 activation
TL;DR: It is demonstrated that AvrRpt2-dependent cleavage of RIN4 at RCS2 is functionally critical in vivo, and at least two bacterial virulence factors target the same domain of R IN4, a approximately 30-aa plant-specific signature sequence found in a small Arabidopsis protein family that may be additional targets for these bacterial virulent factors.
Journal ArticleDOI
An extracellular network of Arabidopsis leucine-rich repeat receptor kinases

TL;DR: It is shown that CSILRR operates as a unified regulatory network in which the LRR-RKs most crucial for its overall structure are required to prevent the aberrant signalling of receptors that are several network-steps away.
