Journal ArticleDOI
Characterization of three members of the Arabidopsis carotenoid cleavage dioxygenase family demonstrates the divergent roles of this multifunctional enzyme family
Michele E. Auldridge,Anna Block,Jonathan T. Vogel,Carole Dabney-Smith,Isabelle Mila,Mondher Bouzayen,Maria Magallanes-Lundback,Dean DellaPenna,Donald R. McCarty,Harry J. Klee +9 more
TL;DR: CCD1 distinguishes itself from other reported CCDs as being the only member not targeted to the plastid, and may have a role in synthesis of apocarotenoid flavor and aroma volatiles, especially in maturing seeds where loss of function leads to significantly higher carotenoids levels.
Journal ArticleDOI
Phytopathogen type III effector weaponry and their plant targets.
TL;DR: The wide array of strategies that bacterial pathogens employ to suppress innate immunity suggest that circumvention of innate immunity is crucial for bacterial pathogenicity of plants.
Journal ArticleDOI
The use of vapor phase extraction in metabolic profiling of phytohormones and other metabolites.
TL;DR: A novel metabolic profiling approach to the analysis of acidic phytohormones and other metabolites based on a simplistic preparation scheme and analysis by chemical ionization-gas chromatography/mass spectrometry is presented and directions for further method expansion are provided.
Journal ArticleDOI
Plant targets for Pseudomonas syringae type III effectors: Virulence targets or guarded decoys?
Anna Block,James R. Alfano +1 more
TL;DR: The phytopathogenic bacterium Pseudomonas syringae can suppress both pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) and effector-triggers immunity (ETI) by the injection of type III effector proteins into host cells.
Journal ArticleDOI
Multiple Hormones Act Sequentially to Mediate a Susceptible Tomato Pathogen Defense Response
Philip J. O'Donnell,Eric A. Schmelz,Anna Block,Otto Miersch,Claus Wasternack,Jeffrey B. Jones,Harry J. Klee +6 more
TL;DR: Tomato actively regulates the Xcv-induced disease response via the sequential action of at least three hormones, promoting expansive cell death of its own tissue.
