Journal ArticleDOI
Isochorismate synthase is required to synthesize salicylic acid for plant defence
TL;DR: By cloning and characterizing an Arabidopsis defence-related gene (SID2) defined by mutation, it is shown that SA is synthesized from chorismate by means of ICS, and that SA made by this pathway is required for LAR and SAR responses.
Journal ArticleDOI
Peroxidase-dependent apoplastic oxidative burst in Arabidopsis required for pathogen resistance
Laurence V. Bindschedler,Julia Dewdney,Kris A. Blee,Julie M. Stone,Tsuneaki Asai,Tsuneaki Asai,Julia M. Plotnikov,Carine Denoux,Tezni Hayes,Chris Gerrish,Dewi R. Davies,Frederick M. Ausubel,G. Paul Bolwell +12 more
TL;DR: Data indicate that peroxidases play a significant role in generating H( 2)O(2) during the Arabidopsis defense response and in conferring resistance to a wide range of pathogens.
Journal ArticleDOI
Activation of defense response pathways by OGs and Flg22 elicitors in Arabidopsis seedlings
Carine Denoux,Roberta Galletti,Nicole Mammarella,Suresh Gopalan,Daniele Werck,Giulia De Lorenzo,Simone Ferrari,Frederick M. Ausubel,Julia Dewdney +8 more
TL;DR: Results suggest a lower threshold for activation of early responses than for sustained or SA-mediated late defenses, and expression patterns of amino-cyclopropane-carboxylate synthase genes also implicate ethylene biosynthesis in regulation of the late innate immune response.
Journal ArticleDOI
Resistance to Botrytis cinerea Induced in Arabidopsis by Elicitors Is Independent of Salicylic Acid, Ethylene, or Jasmonate Signaling But Requires PHYTOALEXIN DEFICIENT3
Simone Ferrari,Roberta Galletti,Carine Denoux,Giulia De Lorenzo,Frederick M. Ausubel,Julia Dewdney +5 more
TL;DR: In Arabidopsis, OGs increase resistance to the necrotrophic fungal pathogen Botrytis cinerea independently of jasmonate (JA)-, salicylic acid (SA)-, and ethylene (ET)-mediated signaling.
Journal ArticleDOI
Genome-wide mapping with biallelic markers in Arabidopsis thaliana
Raymond J. Cho,Michael N. Mindrinos,Michael N. Mindrinos,Daniel R. Richards,R J Sapolsky,M Anderson,Eliana Drenkard,Julia Dewdney,T L Reuber,M Stammers,Nancy A. Federspiel,Athanasios Theologis,Wei-Hsien Yang,Earl Hubbell,M Au,E Y Chung,Deval A. Lashkari,Bertrand Lemieux,Caroline Dean,Robert J. Lipshutz,Frederick M. Ausubel,Ronald W. Davis,Peter J. Oefner +22 more
TL;DR: The construction of a biallelic genetic map in A. thaliana with a resolution of 3.5 cM is reported and its use in mapping Eds16, a gene involved in the defence response to the fungal pathogen Erysiphe orontii is mapped.
