ABSTRACT: This study compared the different gene expression of Bursaphelenchus xylophilus in two growth conditions (growing on Botrytis cinerea and inoculating Pinus thunbergii). The goal was to analyze the specifically-expressed genes of the pine wood nematode involved in the early interaction between B. xylophilus and P. thunbergii and screen the pathogenesis related genes of B. xylophilus. Two-condition experiment, Growing on Botrytis cinerea vs. Inoculating Pinus thunbergii . Biological replicates: 3 replicates.

Project description:Investigation of whole genome gene expression level changes in Botrytis cinerea wild type conidia during germination in comparison to the bmp1 MAP kinase deletion mutant. A 18 chip study using total RNA recovered from four different time points for the wild-type and one time point for the bmp1 deletion mutant. Each time point was analyzed with three biological replicates. Expression level of 20,885 genes from Botrytis cinerea strain B05.10 and T4 with three 60mer probes per gene was analysed.
Project description:Transcriptional profiling of Arabidopsis leaves comparing mock-treated leaves with Botrytis cinerea infected leaves over a time-course (12 and 24 hrs). Two-condition experiment, Mock-treated vs infected leaves. Biological replicates: 5 Mock-treated, 5 infected, independently grown and harvested. One replicate per array.

Project description:This study describes the gel-free phosphoproteomic analysis the phytopathogenic fungi Alternaria brassicicola and Botrytis cinerea grown in vitro under non-limiting conditions.
Project description:Two samples from a larger study of the effect of Botrytis cinerea infection on gene expression in Arabidopsis thaliana. These two samples also form part of an investigation of the sequence dependancy of DNA and RNA fragmentation within ChIP-seq and RNA-seq experiments Two technical replicates from the 24 time point of a time series
Project description:Sound vibration (SV), a mechanical stimulus, can trigger various molecular and physiological changes in plants. Herein, we investigated the effect of SV pre-treatment on Arabidopsis immunity to measure the priming potential of SV. Arabidopsis plants (fourteen-day-old) were treated with sound vibration (1000 Hz, 100 dB) for daily 3 hours up to 10 days in a soundproof chamber. The control plants were kept in a similar sound-proof chamber without SV exposure (daily 3 h) up to 10 days. After that, control and SV-treated plants were challenged with Botrytis cinerea spores. The result showed that SV pre-treatment increases the disease resistance of Arabidopsis against B. cinerea. Samples from three different time points were analyzed through microarray: (1) right after the 10th day of 3h SV treatment (0 h time point), and (2) after Botrytis spore inoculation (12 and 24 hpi time points). RNA was isolated from rosette leaves.
Project description:The goal of the microarray experiment was to identify defense genes that were differentially expressed in the Arabidopsis mutant elp2 and wild type in response to infection of the necrotrophic fungal pathogen Botrytis cinerea. Results indicated that, compared with the wild type, the WRKY33/OCTADECANOID-RESPONSIVE ARABIDOPSIS AP2/ERF59 (ORA59)/ETHYLENE RESPONSE FACTOR1 transcriptional cascades are down-regulated, whereas the MYC2 transcriptional cascade is up-regulated in the elp2 mutant. Three biological replicates with leaves from 8-12 plants per sample were collected at 0, 3, 6, 12, 24, and 48 hours after inoculation with the necrotrophic fungal pathogen Botrytis cinerea. After extraction, RNA concentration was determined on a NanoDrop Spectrophotometer (Thermofisher Scientific, Waltham, MA) and sample quality was assessed using the 2100 Bioanalyzer (Agilent Technologies, Santa Clara, CA). Equal amount of RNA from the 3 biological replicates were used for microarray analysis. The channels of the dual-channel arrays were analyzed independently.
Project description:Current protection strategies against the fungal pathogen Botrytis cinerea rely on a combination of conventional fungicides and host genetic resistance. Defence elicitors can stimulate plant defence mechanisms through a phenomenon known as priming. Priming results on a faster and/or stronger expression of resistance upon pathogen attack. This work aims to study priming of a commercial formulation of the elicitor Chitosan. Treatments with Chitosan result in induced resistance in solanaceous and brassicaceous plants. Large-scale transcriptomic analysis in this study revealed that Chitosan primes gene expression at early time-points after infection. Four conditions were analysed using microarrays: (i) water-treated and non-infected plants (Water + Mock); (ii) Chitosan-treated and non-infected plants (Chitosan + Mock); (iii) water-treated and B. cinerea-infected plants (Water + B. cinerea); (iv) Chitosan-treated and B. cinerea-infected plants (Chitosan + B. cinerea). Inoculations were performed four days after treatment with Chitosan, and leaf discs from four independent plants (biological replicates) per treatment were sampled at 6 h, 9 h and 12 h post-inoculation (hpi) with water mock or B. cinerea spores.
