Pyrus communis: 'Ercolini' cultivar vs. 'Rocha' cultivar

ABSTRACT: Transcriptional profiling of pear tree comparing a resistant/tolerant cultivar with a susceptible cultivar to the Stemphylium vesicarium fungus Rocha' pear is an economically important portuguese Pyrus communis L. cultivar very susceptible to the Stemphylium vesicarium pathogenic fungus, the brown spot agent, causing huge decrease on fruit quality and yield production. Field control of brown spot disease is based in systemic application of antifungal chemicals with high economic costs and dramatic consequences to public health and environmental pollution. Plant-pathogen interactions involve a series of events encompassing constitutive and induced plant defence responses whose dissection has been a research target for control many crop diseases. The biosynthesis of cell wall polymers and antifungal compounds appear to be an efficient physical and chemical barrier to infection.To understand the molecular responses behind defence mechanisms of resistant/tolerant and susceptible cultivars of Pyrus communis L. to the S. vesicarium fungus, cDNA microarray technology was used to identify the genes differentially expressed along a time course leaf inoculation between 'Rocha' pear cultivar (a high susceptible cultivar) and 'Ercolini' pear cultivar (a resistant/tolerant pear cultivar). This study aims to contribute with information on the molecular mechanisms involved in host-pathogen interactions responsible for pear tree brown spot disease and resistance to Stemphylium vesicarium.

Experimental condition: 'Ercolini' vs 'Rocha' (each experiment including 5 plants from each cultivar). 3 time-points: water-inoculation (T0h), 6 hours after inoculation with S. vesicarium (T6h) and 24 hours after inoculation with S. vesicarium. Biological replicates: 3 in each time-point. One replicate per array.

Microarray analysis of fruit flesh of European pear M-bM-^@M-^XLa FranceM-bM-^@M-^Y during fruit development

Project description:Comprehensive investigation of gene expression during fruit development and ripening in European pear (Pyrus communis). Gene expression of fruit flesh development of European pear was measured from -7 to 182 days after full bloom (DAFB). 150 DAFB is harvested stage and 182 DAFB is after ripening by chilling treatment (2M-BM-0C 12 days, then 15M-BM-0C 20 days).

Proteogenomics of Venturia pirina

Project description:This dataset relates to a proteogenomic analysis for Venturia pirina, a fungus that causes scab disease on European pear (Pyrus communis). V. pirina is host specific and infection is thought to be mediated by small, secreted effector proteins. To focus on these effectors we analysed extracts from V. pirina grown in vitro, on cellophane sheets, that mimics the growth habit in infected leaves. LC-MS/MS data was queried against a protein database generated by combining in-silico predicted transcripts with six-frame translations of a whole genome sequence for V. pirina.

Gene expression during early infection of the susceptible spring wheat cultivar Roblin with Fusarium graminearum, the major causal agent of fusarium head blight in wheat

Project description:Fusarium head blight (FHB) is a major disease of cereal crops caused by the fungus Fusarium graminearum (Fg). FHB affects the flowering heads (or spikes). This study compare the gene expression profile in wheat spikelets from the very susceptible spring wheat cultivar Roblin inoculated with water (H2O) or Fg.

Transcription profiling of indica rice cultivar FR13A under salt stress condition.

Project description:A submergence tolerant indica rice cultivar FR13A, was also reported to withstand salt stress and proven in our experiments. The mechanism of tolerance is yet to be studied by forward genetics approach. However, it is known that salt stress tolerance is governed by several QTLs and not by a single gene. To understand the mechanism of such a complex mechanism of salt tolerance we selected, two indica rice genotypes namely, I) FR13A, a tolerant indica variety and ii) IR24, a susceptible genotype for this study. We used the 22K rice Oligoarray from Agilent technologies to study the transcript profile in the leaves of the two contrasting rice genotypes under constitutive and salt stress conditions at seedling stage. Experiment Overall Design: We used Agilent rice gene chips (G4138A) to investigate the transcript level changes in rice plant tissues during salt stress treatment. We used two contrasting rice genotypes (FR13A tolerant and IR24 susceptible) differing in salt stress response. Plants were grown in growth chambers and treated with 150 mM salt concentration at 14th DAS. Sampling was done in both constitutive and treated plants at 3 time points. Two replications of microarray experiments were carried out by hybridizing the RNA from tolerant samples against the susceptible lines on the same slide.

Ave1 Homologs in Venturia pirina and Venturia inequalis

Project description:This dataset relates to a proteomic analysis of Ave1 homologs in the fungal pathogens Venturia pirina and Venturia inequalis. These species are the cause of scab disease on European pear (Pyrus communis) and apple (Malus pumila). Sample preparation for both V. pirina and V. inequalis was designed to focus on effectors and eliminate host proteins. To do this the fungi were grown in vitro, on cellophane sheets mimicing the growth habit in infected leaves and proteins were extracted using a gentle washing procedure designed to avoid cell wall breakage. LC-MS/MS data was queried against a protein database generated from gene predictions obtained from whole genome sequences of V. pirina and V. inequalis.

Transcriptional profiling of indica rice cultivar FR13A under submergence treatment.

Project description:An indica rice cultivar FR13A, is widely grown as submergence tolerant variety and can withstand submergence up to two weeks. The tolerance is governed by a major QTL on chromosome 9 and represented as sub1. Recently the gene for sub1 has been mapped and cloned. However, the trait is governed by several QTLs and not by a single gene. To understand the mechanism of submergence tolerance we selected, two indica rice genotypes namely, I) FR13A, a tolerant indica variety and ii) IR24, a susceptible genotype for this study. We used the 22K rice Oligoarray from Agilent technologies to study the transcript profile in the leaves of the two contrasting rice genotypes under constitutive and submerged conditions at seedling stage. Keywords: Mechanism of submergence tolerance
