(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) We analyzed the interaction between Arabidopsis and western flower thrips (Frankliniella occidentalis), which are one of the most serious insect pests of cultivated plants. A total of 1.2K potential biotic and abiotic stress-related genes were selected from the genes covered by the Arabidopsis 7K array (RIKEN, Japan) and Arabidopsis oligo microarray (Agilent Technologies, USA) for this study. The 21- day-old plants were feeded by western flower thrips in an acryl cylinder chamber with air ventilation windows covered with a fine mesh. more...

(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) Myzus persicae (green peach aphid) feeding on Arabidopsis thaliana induces a defense response, quantified as reduced aphid progeny production, in infested leaves but not in other parts of the plant. Similarly, infiltration of aphid saliva into Arabidopsis leaves causes only a local increase in aphid resistance. Further characterization of the defense-eliciting salivary components indicates that Arabidopsis recognizes a proteinaceous elicitor with a size between 3 to 10 kD. more...

(Submitter supplied) Arabidopsis does not support the growth and asexual reproduction of the barley pathogen, Blumeria graminis f. sp. hordei Bgh). A majority of germlings fail to penetrate the epidermal cell wall and papillae. To gain additional insight into this interaction, we determined whether the salicylic acid (SA) or jasmonate (JA)/ethylene (ET) defence pathways played a role in blocking barley powdery mildew infections. more...

(Submitter supplied) JAV1 functions as a negative regulator to control plant defense. Defense-related genes were highly induced in JAV1 RNAi plants compared to wild-type plants in response to wounding or jasmonate treatments. We used microarrays to detail the global programme of gene expression underlying JAV1 effects on expression of genes involving in defense response, lipid metabolism and regulating transcription.

(Submitter supplied) Plant defense responses to biotic stresses are complex biological processes, all governed by sophisticated molecular regulations. Induced systemic resistance (ISR) is one of these defense mechanisms where beneficial bacteria or fungi prime plants to resist pathogen or pest attacks. In ISR the defense arsenal in plants remains dormant and it is only triggered by the infection, allowing a rapid response and a better allocation of plant resources. more...
