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.

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: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:Capsicum spp. (hot peppers) demonstrate a range of interesting bioactive properties spanning anti-inflammatory, antioxidant, and antimicrobial activities. While several species within the genus are known to produce antimicrobial peptides (AMPs), AMP sequence mining of genomic data indicates this space remains largely unexplored. Herein, in silico AMP predictions are paired with peptidomics to identify novel AMPs from the interspecific hybrid ghost pepper (Capsicum chinense x frutescens). AMP prediction algorithms reveal 115 putative AMPs within the Capsicum chinense genome of which 14 were identified in the aerial tissue peptidome. PepSAVI-MS, de novo sequencing, and complementary approaches were used to fully molecularly characterize two novel AMPs, CC-AMP1 and CC-AMP2, including elucidation of post-translational modifications and disulfide bond connectivity. Both CC-AMP1 and CC-AMP2 have little homology with known AMPs and exhibit low µM antimicrobial activity against gram-negative bacteria including Escherichia coli and Klebsiella pneumoniae. These findings demonstrate the complementary nature of peptidomics, bioactivity-guided discovery, and bioinformatics-based investigations to more fully characterize plant AMP profiles.

Project description:The organization of chromatin into self-interacting domains is universal among eukaryotic genomes, though how and why they form varies considerably. Here we report a chromosome-scale reference genome assembly of pepper (Capsicum annuum) and explore its 3D organization through integrating high-resolution Hi-C maps with epigenomic, transcriptomic, and genetic variation data. Chromatin folding domains in pepper are as prominent as TADs in mammals but exhibit unique characteristics. They tend to coincide with heterochromatic regions enriched with retrotransposons and are frequently embedded in loops, which may correlate with transcription factories. Their boundaries are hotspots for chromosome rearrangements but are otherwise depleted for genetic variation. While chromatin conformation broadly affects transcription variance, it does not predict differential gene expression between tissues. Our results suggest that pepper genome organization is explained by a model of heterochromatin-driven folding promoted by transcription factories and that such spatial architecture is under structural and functional constraints.

Project description:ngs2013_07_pcapsici-effecaps-phytophthora capsici-The analysed RNAseq concerned the oomycete Phytophthora capsici in growth on pepper plants. 1/ How the adaptation of a pathogen to a host depends on its gene expression? 2/ How the plant host impacts the expression of pathogen genes at the very beginning of infection?-Two isolates of Phytophthora capsici were used: the Pc107 isolate (called A for adapted to pepper from INRAE GAFL Avignon), and the Pc273 isolate (N for non-adapted to pepper, collected on pumpkin in the USA). Two accessions of pepper (Capsicum annuum L., the host) were used: Yolo Wonder (YW, PM0031), susceptible (S) to Phytophthora capsici, and Criollo de Morelos 334 (CM334, PM0702), partially resistant (R). Inoculations were performed, as described in Lefebvre and Palloix (1996), by putting on the wounded stem a plug of mycelium. Inoculated plants were transferred to a growth chamber at 24°C/22°C temperature on a 12h/12h light/dark cycle. At 24 hours-post-inoculation, 12 total RNA samples were extracted from inoculated plants for the 4 host-isolate interactions: R_A, S_A, R_N and S_N. Each sample consisted of six pooled stem fragments. The stem fragments are the 5-mm region immediately under the visible stem necrosis. Samples were flash-frozen in liquid-nitrogen and stored at -80ºC. They were ground in liquid nitrogen with a cold mortar and pestle. Total RNA was extracted using QIAGEN Rneasy Plant Mini Kit. RNA-seq libraries were constructed at IPS2 POPS platform (France) by TruSeq_Stranded_mRNA_SamplePrep_Guide_15031047_D protocol (Illumina®, California, USA). Sequencing was conducted on an Illumina Hiseq2000 hosted by Genoscope (Evry, France). The RNA-seq samples have been sequenced in paired-end (PE) with a sizing of 260 bp and a read length of 100 bases, lane repartition and barcoding giving approximately 35 million of paired-end reads per sample.

Project description:Antimicrobial peptides (AMPs) are compounds with a variety of bioactive properties. Especially promising are their antibacterial activities, often towards drug-resistant pathogens. Across different AMP sources, AMPs expressed within plants are relatively underexplored, with a limited number of plant AMP families identified. Recently, we identified the novel AMPs CC-AMP1 and CC-AMP2 in ghost pepper plants (Capsicum chinense x frutescens), exerting promising antibacterial activity and not classifying into any known plant AMP family. Herein, AMPs related to CC-AMP1 and CC-AMP2 were identified within both Capsicum annuum and Capsicum baccatum. Targeted MS/MS experiments were performed to determine peptide sequences, guided by in silico AMP sequence predictions.
