(Submitter supplied) Expression profiling of wild-type plants and mutants with defects in key components of the defense signaling network was used to model the Arabidopsis network 24 hours after infection by Pseudomonas syringae pv. maculicola strain Psm ES4326. Results using the Affymetrix ATH1 array revealed that expression levels of most pathogen-responsive genes were affected by mutations in coi1, ein2, npr1, pad4, or sid2. more...

(Submitter supplied) Salicylic acid (SA)-induced defense responses are important factors during effector triggered immunity and microbe-associated molecular pattern (MAMP)-induced immunity in plants. This article presents evidence that a member of the Arabidopsis CBP60 gene family, CBP60g, contributes to MAMP-triggered SA accumulation. CBP60g is inducible by both pathogen and MAMP treatments. Pseudomonas syringae growth is enhanced in cbp60g mutants. more...

(Submitter supplied) The Arabidopsis Pathoarray 464_001 (GPL3638) was used to compare response of Col-0, pad4-1 (Zhou et al., 1998; Jirage et al., 1999) and sid2-2 (Wildermuth et al., 2001) to Pseudomonas syringae pv. tomato DC3000 hrcC mutant. SA production is drastically reduced in sid2 mutants. PAD4 is required for SA-mediated responses. The results suggested that the SA increase triggered by MAMPs is one major component in the MAMPs-triggered signaling mechanism. more...

(Submitter supplied) Plant defenses against pathogens and insects are regulated differentially by cross-communicating signaling pathways in which salicylic acid (SA), jasmonic acid (JA) and ethylene (ET) play key roles. To understand how plants integrate pathogen- and insect-induced signals into specific defense responses, we monitored the dynamics of SA, JA, and ET signaling in Arabidopsis after attack by a set of microbial pathogens and herbivorous insects with different modes of attack. more...

(Submitter supplied) The Arabidopsis Pathoarray 464_001 (GPL3638) was used to compare response of wild-type, rps2-101C (Bent et al., 1994; Mindorinos et al., 1994) and ndr1-1 (Century et al., 1995) to Pseudomonas syringae strain expressing avrRpt2. The two mutants are compromised in RPS2-mediated resistance but distinct difference between them has not been described. The results suggested that ndr1-1 affects a defense signaling pathway(s) in addition to the RPS2-dependent pathway, and indicate that the microarray is a powerful tool for systems analysis of the Arabidopsis disease signaling network. more...

(Submitter supplied) In order to protect themselves from pathogens, plants activate a battery of defense pathways, many of which involve changes in gene expression.

(Submitter supplied) Pseudomonas syringae pv. tomato DC3000 is a model pathogen infecting tomato and Arabidopsis plants. Genes encoding the type III secretion system and substrate proteins (collectively called TTSS genes) of this bacterium are induced in plants and in minimal medium (MM). The induction of TTSS genes is mediated by HrpL, an alternative sigma factor recognizing the hrp box in the promoter of TTSS genes. The transcription of hrpL is activated by HrpR and HrpS, two homologous DNA binding proteins encoded by the hrpRS operon. more...

(Submitter supplied) The pathogen Agrobacterium tumefaciens infects a broad range of plants, introducing the T-DNA into their genome. Contrary to all known bacterial phyto-pathogens, Agrobacterium lacks the hypersensitive response-inducing HRP genes although it introduces numerous proteins into the plant cell through a type IV secretion system. To understand the timing and extent of the plant transcriptional response to this unusual pathogen, we used an Arabidopsis 26-thousand gene oligonucleotide microarray. more...

(Submitter supplied) Chitin, a polymer of N-acetyl-glucosamne, is a component of the cell walls of many plant fungal pathogens. During the infection process, the released chitin fragments (such as chitooctaose) from fungal cell walls by plant enzymes can trigger plant defense response and gene activation. The current work studies the regulation of Arabidopsis genes by the purified chitin fragment chitooctaose. We used the Affymetric Arabidopsis whole gene arrays to study the gene expression caused by chitin (chitooctaose). more...
