Project description:We report the sRNA profile upon dsRNA spraying on 16C (Nicotiana benthamiana) plants. In this experiment we could detect only the degradation products of the dsRNA, which indicates absence of further processing of the dsRNA by RNAi machinery

Project description:The associated experiments document the production of small RNA (sRNA) during the expression of Cas13 and crRNA, crRNA alone, or controls from agrobacterium spot infiltration in Nicotiana benthamiana. We document the specific production of sRNA corresponding to the guide sequence of the targeted mRNA. In cases where a multi-guide crRNA or a hairpin were expressed, abundent sRNA are produced correspinding to the target mRNA, but outside of the corresponding guide sequence site.

Project description:Small RNA (sRNA)-guided RNA silencing is a critical antiviral defense mechanism employed by a variety of eukaryotic organisms. Although the induction of RNA silencing by bipartite and monopartite begomoviruses has been described in plants, the nature of begomovirus/betasatellite complexes remains undefined. We profiled Tomato yellow leaf curl China virus (TYLCCNV) and its associated betasatellite (TYLCCNB)-derived small RNAs (V-sRNAs and S-sRNAs) using Solexa-based deep sequencing to evaluate the role of betasatellites in V-sRNA modulation. Both sense and anti-sense V-sRNAs and S-sRNAs accumulated preferentially as 22 nucleotide species in infected Solanum lycopersicum and Nicotiana benthamiana plants, indicating that secondary siRNAs were triggered. High resolution mapping of V-sRNA and S-sRNA revealed heterogeneous distribution of V-sRNA and S-sRNA sequences across the TYLCCNV and TYLCCNB genomes. In TYLCCNV-infected S. lycopersicum or N. benthamiana and TYLCCNV and betaC1-mutant TYLCCNB co-infected N. benthamiana plants, the primary TYLCCNV targets were AV2 and the 5’ terminus of AV1. In TYLCCNV and betasatellite-infected plants, the number of V-sRNAs targeting this region decreased and the production of V-sRNAs increased corresponding to the overlapping regions of AC2 and AC3, as well as the 3’ terminal of AC1. betaC1 is the primary determinant mediating symptom induction and also the primary silencing target of the TYLCCNB genome even in its mutated form. In addition, the betasatellite affected the amount of V-sRNAs detected in S. lycopersicum and N. benthamiana plants.

Project description:To systematically investigate viral sRNA production and sRNA-target interaction, we sequenced sRNAs from Tobacco Rattle Virus (TRV)-infected Nicotiana benthamiana at an early (1 week post infection) and late time point (3 weeks post infection). The N. benthamiana 16c plants were infected with TGS-inducing viruses (TRV-35S and TRV-35-2M) and PTGS-inducing viruses (TRV-GFP and TRV-GFP-2M), respectively. TRV-35S is a recombinant TRV containing a 120 nt segment of the 35S promoter. Its derivative, TRV-35S-2M, carrying single nucleotide substitutions (SNS) at every 10 nt within the 120 nt 35S target segment. Same strategy was used to create recombinant TRV-GFP and TRV-GFP-2M targeting GFP coding sequence. According to SNS content, sRNAs from TRV-35S-2M/TRV-GFP-2M infected plants can be separated to yield primary (containing SNSs) and secondary sRNAs (lacking SNSs). Wild Type TRV was used along as viral infection control. Libraries were indexed during PCR amplification (16 cycles) according to the Illumina protocol. See individual sample information for specific index primers used.

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:Nicotiana benthamiana plants were infected with Asparagus Virus 2 and its mutant version. Upper non-inoculated leaves were collected at various time points and used for sample preparation. RNA-seq was performed on the WT infected, mutant infected and mock uninfected samples. Ribo-seq was performed on the WT infected and mutant infected samples.

Project description:Species from the genus Colletotrichum are the causal agents of anthracnose which contribute to significant losses to the production of commercially grown crops. The genomes of Colletotrichum orbiculare, which infects cucurbits and Nicotiana benthamiana, as well as Colletotrichum gloeosporioides, which infects a wide range of fruits and vegetables, were sequenced. A custom microarray was designed for Colletotrichum orbiculare and used to assess gene expression during infection of Nicotiana benthamiana. Gene expression of Colletotrichum orbiculare growing on its host Nicotiana benthamiana was assessed at 24 hours post inoculation, 3 days post inoculation and 7 days post inoculation. Mycelia growing in vitro and ungerminated conidia were used as controls. Three replicates were performed for each time point.
