Project description:Purpose: The tomato psyllid, Bactericera cockerelli Šulc (Hemiptera: Triozidae), is a pest of tomato (Solanum lycopersicum) and potato (S. tuberosum) in the U.S. and vectors the disease-causing pathogen ‘Candidatus Liberibacter solanacearum’. Plants undergo physiological, transcriptomic, or epigenetic changes in order to mount a stronger, faster response against secondary challenges by previously perceived threats. This is called defense ‘priming’ and it likely has an impact on vectored disease transmission. Currently, it is still unknown whether or not psyllid infestation has any lasting consequences for tomato gene expression or defense. To characterize the genes potentially involved in tomato priming against psyllids, RNA was extracted from psyllid-primed and uninfested tomato (Moneymaker) leaves three weeks after infestation. Methods: RNA was extracted and sequenced from plants three weeks after psyllid infestation. Plants were either left alone (Control or C) or infested with psyllids (Primed or J1). Libraries were developed using the TruSeq RNA Library Prep Kit v2. Sequencing was performed on the Illumina PE HiSeq 2500 v4 platform. Processed sequences were uploaded to the CyVerse Discovery Environment computational infrastructure where bioinformatic analysis was performed using the Tuxedo Suite 2 workflow. Results: Illumina HiSeq sequencing of tomato cDNA libraries produced 132,428,443 total reads that met FastQC quality control criteria. 94.6% of all reads mapped to vSL3.0 of the S. lycopersicum genome. CuffDiff2 analysis identified 310 differentially expressed genes (DEGs) between control and psyllid-primed plants (q-value <0.01). Conclusions: A week-long infestation by a small number of B. cockerelli had lasting consequences for gene expression in tomato plants. Homologs of the DEGs were associated with 1) defense against abiotic and biotic stress, 2) growth and development, and 3) components of plant biology indirectly involved in plant growth and development such as homeostasis, transcription/translation, and molecular transport.

Project description:In order to compare the small RNA (sRNA) population between the control and Potato spindle tuber viroid (PSTVd) upon infecting the plants, the tomato plants (Lycopersicum esculentum cv. Rutgers) were mock inoculated. At 21 dpi,tTotal RNA was extracted and subjected for deep-sequencing using Illumina MiSeq platform. The primers were trimmed and the 21- to 24-nt long small RNA species were filtered after quality check of the raw data.

Project description:In order to analyze the production of small RNA (sRNA) by Potato spindle tuber viroid- RG1 strain (PSTVd-RG1) upon infecting the plants, the tomato plants (Lycopersicum esculentum cv. Rutgers) were inoculated with the PSTVd-RG1. After 21-days of post inoculation, total RNA was extracted and subjected for deep-sequencing using Illumina MiSeq platform. The primers were trimmed and the 21- to 24-nt long small RNA species were filtered after quality check of the raw data.

Project description:In order to analyze the production of small RNA (sRNA) by Potato spindle tuber viroid-intermediate strain (PSTVd-I) upon infecting the plants, the tomato plants (Lycopersicum esculentum cv. Rutgers) were inoculated with the PSTVd-I. After 21-days of post inoculation, total RNA was extracted and subjected for deep-sequencing using Illumina MiSeq platform. The primers were trimmed and the 21- to 24-nt long small RNA species were filtered after quality check of the raw data.

Project description:To further clarify the differences in the potential regulatory mechanisms of cold tolerance between wild and cultivated tomatoes, we subjected cold-sensitive cultivated tomato (Solanum lycopersicum) Ailsa Craig (AC) and cold-tolerant wild tomato (S. habrochaites) LA1777 to cold stress for 6 h, and performed ATAC-Seq and RNA-Seq, respectively.

Project description:Tomato is a major global crop however its production is limited by Botrytis cinerea. Due to the toxicity of post-harvest pesticide application, alternative control methods such as priming are being investigated. Plants were treated with β-aminobutyric (BABA) at two developmental stages and resistance against B. cinerea was tested in fruit tissue and in progenies. DNA methylation and RNA sequencing were conducted to characterise the (epi)genetic changes associated with long-lasting resistance. Grafting experiments were done to assess the systemic nature of this signal, which was further characterised by small RNA (sRNA) sequencing of scions. Only BABA-treated seedlings displayed induced resistance (IR). DNA methylation analysis revealed seedling-specific changes, which occurred in the context of lower basal methylation. BABA-IR was found to be transmissible from primed rootstock to grafted unprimed scions. In these scions, we identified a subset of mobile 24 nt sRNAs associated with primed genes to infection in fruit. Our results demonstrate the functional association of a systemic signal with long lasting IR and priming. Through integrated omics approaches we have identified markers of long-lasting priming in tomato fruit which could also serve as targets for durable resistance in other crops.

Project description:The intent of the experiment was to infer, from transcriptome analysis, the occurrence of competent LTR retrotransposons in shoot apical meristems of Solanum lycopersicum. For this, we performed Illumina pair-end RNA-seq in M82 tomato samples of meristems, leaves and flowers. We also harvested meristems in plants subjected to long-term heat. In addition, we performed RNA-seq in meristems, leaves and flowers samples from Solanum pennellii, to aid phylogenetic interpretations.

Project description:Arabidopsis thaliana (Col-0) plants were treated with BABA and gene expression differences to control plants were monitored after dip-inoculation with Pseudomonas syringae pv tomato DC3000. Keywords: transcript profiling, response to BABA-induced priming and infection 3 independant replicates were analyzed by two color co-hybridizations. Leaf RNA from Pseudomonas infected control plants (Cy3 labeled cDNA) was cohybridized with leaf RNA from Pseudomonas infected BABA pretreated plants (Cy5 labeled cDNA). Samples were collected 22 hours after bacterial inoculation. BABA pretreatment was performed two days before bacterial inoculation. To assess the effect of BABA alone on gene expression, leaf RNA from BABA treated plants (Cy5 labeled cDNA) was cohybridized with leaf RNA (Cy3 labeled cDNA) from water treated plants.
