Project description:Infestation with white-backed planthopper (WBPH) to rice caused induced resistance to rice pathogens but brown planthopper (BPH) infestation induce weaker resistance to rice pathogens. We compared changes in gene expression in rice plants infested with WBPH and BPH to gain some insight into the WBPH-induced resistance to rice pathogens. An analysis, using microarrays, of gene expression in rice plants infested with these planthoppers revealed that WBPH infestation caused high induction of many defense-related genes including pathogenesis-related (PR) genes than BPH infestation. Furthermore, hydroperoxide lyase 2 (OsHPL2) which is an enzyme to produce C6 volatiles was induced by WBPH infestation, but not by BPH infestation. Keywords: response to herbivory; induced resistance

Furthermore, hydroperoxide lyase 2 (OsHPL2) which is an enzyme to produce C6 volatiles was induced by WBPH infestation, but not by BPH infestation. Experiment Overall Design: Agilent rice oligo microarray was used to investigate the gene expression profiling in rice plants infested with WBPH or BPH. Total RNA was extracted from pooled leaf blades infested with WBPH or BPH for 24 h and from mock-treated pooled leaf blades. Total RNA (200 ng) was labeled with Cy-3 or Cy-5 using an Agilent low RNA input linear amplification kit. Fluorescently labeled targets were hybridized to Agilent rice oligo microarrays. Hybridization and wash processes were performed according to the manufacturerâ??s instructions, and hybridized microarrays were scanned using an Agilent DNA microarray scanner. Agilent Feature Extraction software was employed for the image analysis and data extraction processes. Fold changes in expression level in each treatment were compared with those of the respective mock-treated controls. In each treatment, the experiment was performed independently three times.

Project description:Reactive nitrogen species (RNS) derived from dietary and salivary inorganic nitrates (NO3-) foment innate host defenses associated with the acidity of the stomach. The mechanisms by which these reactive species exert antibiotic activity in the gastric lumen are, however, poorly understood. To identify targets of RNS, the genetically tractable acid tolerance response (ATR) that enables enteropathogens to survive the harsh acidity of the stomach was screened for signaling pathways responsive to RNS. The nitric oxide (NO) donor spermine NONOate derepressed the Fur regulon that controls secondary lines of resistance against organic acids. Despite inducing a Fur-mediated adaptive response, acidified RNS largely boosted gastric host defenses as demonstrated by the fact that Salmonella bacteria exposed to spermine NONOate during mildly acidic conditions were not only shed in low amounts in feces, but also exhibited ameliorated oral virulence. NO prevented Salmonella from mounting a de novo ATR, but was unable to suppress an already functional protective response, indicating that RNS target regulatory cascades but not the effectors that defend against the rigors of gastric acidity. Transcriptional and translational analyses revealed that the PhoPQ signaling cascade is a critical ATR target of NO in rapidly growing Salmonella. Inhibition of PhoPQ signaling appears to contribute to most of the NO-mediated abrogation of the ATR in log phase bacteria, because the augmented acid sensitivity of phoQ-deficient Salmonella was not further enhanced after RNS treatment. Since PhoPQ-regulated acid resistance is widespread in enteric pathogens, the RNS-mediated inhibition of the Salmonella ATR described herein may represent a common component of the innate host defenses of the gastric lumen. Keywords: acid tolerance response, nitric oxide Microarray analyses were conducted comparing transcript levels of log-phase Salmonella cultured in minimal E salts + 0.4% glucose, pH 4.4 in the presence or absence of 250 µM spermine NONOate for 1 hour. Microarrays were performed in triplicate under identical conditions (3 biological replicates).
