Project description:Two fruit development stages of the wild chiltepin pepper (Capsicum annuum var. glabriusculum) were studied. RNA-Seq data was obtained from fruits at 20 and 68 days after anthesis with two biological replicates for a total of 4 samples. 260 million raw reads were sequenced and over 80% of them mapped back to the Capsicum annuum genome.
Project description:Pepper(Capsicum annuum L.) fruit development is a complex and genetically programmed process, a comparative study of transcriptome and proteome changes during two varieties of pepper development(IMG, MG, Br and MR) has been carried out by using RNA-Seq and Lable-free quantitation technology.

Project description:Small RNAs (21-24 nt) are pivotal regulators of gene expression that guide both transcriptional and post-transcriptional silencing mechanisms in diverse eukaryotes, including most if not all plants. MicroRNAs (miRNAs) and short interfering RNAs (siRNAs) are the two major types, both of which have a demonstrated and important role in plant development, stress responses and pathogen resistance. In this work, we used a deep sequencing approach (Sequencing-By-Synthesis, or SBS) to develop sequence resources of small RNAs from different Capsicum annuum tissues (including leaves, flowers and fruit). The high depth of the resulting datasets enabled us to examine in detail critical small RNA features, such as size distribution, tissue-specific regulation and sequence conservation between different organs in this species. We also developed database resources and a dedicated website (http://smallrna.udel.edu/) with computational tools for allowing other users to identify new miRNAs or siRNAs involved in specific regulatory pathways, verify the degree of conservation of these sequences in other plant species and map small RNAs on genes or larger regions of the maize genome under study. Small RNA libraries were derived from leaves, flowers and fruit of Capsicum annuum. Total RNA was isolated using the TriReagent (Molecular Research Center) for leaves and flowers and the Plant RNA Purification Reagent (Invitrogen) for fruit, and submitted to Illumina (Hayward, CA, http://www.illumina.com) for small RNA library construction using approaches described in (Lu et al., 2007) with minor modifications. The small RNA libraries were sequenced with the Sequencing-By-Synthesis (SBS) technology by Illumina. PERL scripts were designed to remove the adapter sequences and determine the abundance of each distinct small RNA. We thank Barbara Baker for providing the plant material, as well as Kan Nobuta and Gayathri Mahalingam for assistance with the computational methods.
Project description:The colonization of Capsicum annuum roots by Fusarium oxysporum Fo47 induces resistance responses on the plant. Fo47 is a non-pathogenic strain of Fusarium oxysporum. Fo47 colonizes only the most outer layers of the root surface but it does not colonize inner tissues. Pre-treatment of roots with Fo47 reduces the symptom development produced by later pathogen inoculation. The expression of genes in distal tissues was determined by microarray analysis of stems of Fo47-treated plants. Capsicum annuum samples were analyzed using Affymetrix chips of the close-related species Solanum lycopersicum.

Project description:Six different Solanaceae species, Potato (Solanum tuberosum), Tomato (Lycopersicum esculentum), Pepper (Capsicum annuum), Tobacco (Nicotiana tabacum), Petunia and Nicotiana benthamiana were grown at 25C, 16h light and 8h darkness. Mature leaves were harvested after 4-6 weeks. RNA was isolated using Qiagen RNeasy. Tomato, pepper, petunia tobacco and N. benthamiana samples were hybridized against potato samples.

Project description:Using Illumina platform, deep sequencing of 12 small RNA libraries was performed from Helicoverpa armigera larvae fed on artificial diet (AD) or recombinant Capsicum annuum PI-7 (rCanPI-7) incorporated diet at various time intervals (0.5, 2, 6, 12, 24, and 48h). Several candidate miRNAs (conserved and novel) were differentially expressed in rCanPI-7 fed larvae as compared to the larvae fed on AD. The investigation revealed potential roles of miRNAs in H. armigera protease gene regulation.

Project description:Twelve chili pepper accessions, six domesticated, four wild and two F1 crosses were studied. RNA-Seq experiments were performed with fruits from each accession at 7 different times after anthesis. Additionally, samples of seedlings from two accessions were evaluated. The data set is comprised by 179 samples, that in total have more than 3 billion reads map to the Capsicum annuum genome.
