Project description:TMV-resistant (N), -susceptible (n), and enhanced susceptible mutant sun1-1 (N) tomato were grown in asceptic conditions in growth chambers (25º, 16hr/8hr light dark). 4-5 week old tomato were treated with TMV leaf sap or mock leaf sap, and leaf tissue was collected after 3, 9, and 27 hours. RNA was isolated from each sample (leaf tissue from one plant/one treatment/one timepoint), using standard TIGR protocols, and 25ug of total RNA was labeled using TIGR indirect labeling protocols. The experiment was repeated three times. Keywords: Direct comparison

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.

Proteomic analysis of early stage infection in the tobacco-Tobacco mosaic virus (TMV)

Project description:The early events of virus infection is one of the more poorly understood areas of plant virology and studies on the effect of virus on the host proteome at very early stages of infection are lacking. In the present study, we analysed the proteome on the early stage changes at 15 minutes post inoculation in the tobacco-TMV pathosystem with and without exogenous application of dsRNA p126
