SRNA sequencing of TRV-infected Nicotiana benthamiana 16c

ABSTRACT: 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.

sRNA sequencing of TRV-infected Nicotiana benthamiana 16c at 29oC

Project description:To investigate how high temperature affects sRNA production during virus induced gene silencing (VIGS), we sequenced sRNAs from Tobacco Rattle Virus (TRV)-infected Nicotiana benthamiana kept at 29°C at an early (1 week post infection) and a late time point (3 weeks post infection). To compare sRNA production between virus induced transcriptional gene silencing (ViTGS) and virus induced post-translational gene silencing (ViPTGS) at 29°C, 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). 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.

RNA sequencing of NlCSP11-infiltrated Nicotiana benthamiana

Project description:In order to find the differentially expressed RNAs and signaling pathways related to the dwarf phenotype induced by NlCSP11, 35S-NlCSP11, 35S-XopQ and 35S-GFP control were infiltrated into Nicotiana benthamiana. We analyzed the differentially expressed RNAs in the infiltrated leaves (NlCSP11_Z/XopQ_Z) and the upper uninfiltrated leaves (NlCSP11_U/XopQ_U) of N. benthamiana. KEGG annotation revealed a large number of differentially expressed RNAs involved in plant-pathogen interactions, indicating that NlCSP11 resulted in a more strong systemic resistance in N. benthamiana.

Small RNA sequencing of NlCSP1-infiltrated Nicotiana benthamiana

Project description:In order to find the miRNAs, target genes and signaling pathways related to the dwarf phenotype induced by NlCSP1, 35S-NlCSP1 and 35S-GFP control were infiltrated into Nicotiana benthamiana. We analyzed the differentially expressed miRNAs in the infiltrated leaves (NlCSP1_Z/GFP_Z) and the upper uninfiltrated leaves (NlCSP1_O/GFP_O) of N. benthamiana. A total of 106 and 97 differentially expressed miRNAs were identified in NlCSP1_Z/GFP_Z and NlCSP1_O/GFP_O, respectively. KEGG annotation revealed a large number of differentially expressed miRNAs involved in plant hormone signal transduction, indicating that NlCSP1 changed the hormone signal pathway in N. benthamiana.

NGS data of Nicotiana benthamiana 16c plants after CRISPR/Cas9 gene editing

Project description:Provided data came from a detailed study on Nicotiana benthamiana 16c plants where we use Tobacco Rattle Virus (TRV) as a molecular switch to change the chromatin state of a reporter gene (P35S::GFP) from an actively transcribed to a transcriptionally silenced state. Our approach enables us to interrogate different chromatin states of the same locus with the same set of CRISPR/Cas9 genome editing reagents and systematically describe the effect of chromatin state on the frequency and type of mutations induced at various Cas9 targets in a huge set of independently edited cells.

Small-RNA sequencing of WUS-induced GFP RNA degradation in Nicotiana benthamiana leaves

Project description:The 35S::GFP fluorescence was silenced 6-day after infiltration to Nicotiana benthamiana leaves due to the post-transcriptional gene silencing, but became stable by adding the viral suppressor 2b which repressed RNA silencing in plants. We performed the small RNA high throughput sequencing to test whether WUS can inhibit 2b functions in repressing plant RNA silencing.

small RNAs sequences from grafted Arabidopsis thaliana and Nicotiana benthamiana tissues

Project description:A silencing signal in plants with an RNA specificity determinant moves through plasmodesmata and the phloem. To identify the mobile RNA we grafted Arabidopsis thaliana shoots to roots that would be a recipient for the silencing signal. Using high throughput sequencing as a sensitive detection method and mutants to block small RNA (sRNA) biogenesis in either source or recipient tissue, we detected endogenous and transgene specific sRNA that moved across the graft union. Surprisingly we found that the mobile endogenous sRNAs account for a substantial proportion of the sRNA in roots and we provide evidence that 24nt mobile sRNAs direct epigenetic modifications in the genome of the recipient cells. Mobile sRNA thus represents a mechanism for transmitting the specification of epigenetic modification and could affect genome defence and responses to external stimuli that have persistent effects in plants.

Characterization of small interfering RNAs derived from the geminivirus/betasatellite complex using deep sequencing

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. characterization of Tomato yellow leaf curl China virus and Tomato yellow leaf curl China betasatellite-derived small interfering RNAs from five cDNA libraries of two plant species

Potato virus Y HCPro suppression of antiviral silencing in Nicotiana benthamiana plants correlates with its ability to bind in vivo to small RNAs of 21 and 22 nucleotides in length of viral sequence

Project description:We have investigated short and small RNAs (sRNAs) that were bound to a biologically active hexahistidine-tagged Potato virus Y (PVY) HCPro suppressor of silencing, expressed from a heterologous virus vector in Nicotiana benthamiana plants, and purified under non-denaturing conditions. We found that RNAs in purified preparations were differentially enriched in sRNAs of 21 and to a much lesser extent of 22 nucleotides (nt) in length and of viral sequence (vsRNAs) when compared to those found in a control plant protein background bound to the nickel resin in the absence of HCPro, or in a purified alanine substitution HCPro mutant (HCPro mutB) control that lacked suppressor of silencing activity. In both controls, sRNAs were composed almost entirely by molecules of plant sequence, indicating that the resin-bound protein background had no affinity for vsRNAs, and also that HCPro mutB failed to bind to vsRNAs. Therefore, PVY HCPro suppressor activity correlated with its ability to bind to 21 and 22 nt vsRNAs. HCPro constituted at least 54 % of the total protein content in purified preparations and we were able to calculate its contribution to the 21 and the 22 nt pool of sRNAs present in the purified samples and its binding strength relative to the background. We also found that in the 21 nt vsRNAs of the HCPro preparation 5´ terminal adenines were overrepresented relative to the controls, but not in vsRNAs of other sizes or of plant sequence.
