Tobacco mosaic virus infection alters phloem associated translatomes in Nicotiana benthamiana

Project description:In this study we used vascular specific promoters and a translating ribosome affinity purification strategy to identify phloem-associated translatome responses to infection by tobacco mosaic virus (TMV) in the systemic host Nicotiana benthamiana. Three different promoter:FLAG-RPL18 lines were used. These included two phloem specific promoters (pSUC2 and pSULTR2;2) as well as the more ubiquitously expressed cauliflower mosaic virus 35S promoter (p35S). Immunopurification of ribosome-mRNA complexes was accomplished by the method described in Reynoso et al. (Plant Functional Genomics: Methods and Protocols, 185-207; 2015). The dataset includes samples from the leaves of 5-week-old plants inoculated with TMV (1 mg/mL) or mock inoculated with sterile water.

Strigolactones negatively regulate Tobacco mosaic virus resistance in Nicotiana benthamiana

Project description:Strigolactones (SLs) are plant hormones that regulate diverse developmental processes and environmental responses in plants. It has been discovered that SLs play an important role in regulating plant immune resistance to pathogens, but there are currently no reports on their role in the interaction between Nicotiana benthamiana and Tobacco mosaic virus (TMV). In this study, the exogenous application of SLs weakened the resistance of N. benthamiana to TMV, promoting TMV infection, whereas the exogenous application of Tis108, an SL inhibitor, resulted in the opposite effect. Virus-induced gene silencing (VIGS) inhibition of two key SL synthesis enzyme genes, NtCCD7 and NtCCD8, enhanced the resistance of N. benthamiana to TMV. Additionally, we conducted a screening of N. benthamiana related to TMV infection. TMV-infected plants treated with SLs were compared to the control by using RNA-seq. KEGG enrichment analysis and weighted gene co-expression network analysis (WGCNA) of differentially expressed genes (DEGs) suggested that plant hormone signaling transduction may play a significant role in the SL-TMV-N. benthamiana interactions. This study reveals new functions of SLs in regulating plant immunity and provides a reference for controlling TMV diseases in production.

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.

sRNA sequencing of TRV-infected Nicotiana benthamiana 16c

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.

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. 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.

Comparative proteomic analysis of Nicotiana benthamiana plants under CWMV infection

Project description:Chinese wheat mosaic virus (CWMV) is a severe threat to winter wheat, but the mechanism of the viral pathogenic mechanism is poorly understood. In this study, a LC-MS/MS-based quantitative proteomics was conducted to analyze the proteomic changes of CWMV-infected Nicotiana benthamiana compared to mock plants. In total, 2,751 identified host proteins were identified, 1,496 of which were quantified. 146 up-regulated and 248 down-regulated proteins were characterized as differently accumulated proteins (DAPs)
