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.

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.

Rootstock induced scion resistance against tobacco mosaic virus is associated with the induction of defense related transcripts and graft transmissible mRNAs

Project description:To investigate graft conferred resistance against viral diseases a novel hetero-grafting system was developed using Nicotiana benthamiana scions grafted onto different tomato rootstocks. RNAseq analysis was used to identify mobile tomato mRNAs within N. benthamiana scions

Label-free quantitative proteomics on Nicotiana benthamiana plasmodesmal proteome following viral infection

Project description:We analyzed the PD-enriched fraction from Turnip mosaic virus (TuMV)-infected Nicotiana benthmiana (N. benthamiana) by using label-free quantitative proteomics of which 100 and 48 were significantly increased and decreased respectively when compared with mock plants.

Expression analysis of systemically infected Nicotiana benthamiana infected by South African cassava mosaic virus (SACMV)

Project description:Micrarray analysis was used to identify gene expression changes associated with disease development and virus movement in N.benthamina plants induced by infection with the SACMV 1-Plex , 385K array Nicotiana benthamiana (NimbleGen design name: 110121_N_benthamiana_60mer_exp) was used in this study to monitor changes in gene expression levels in SACMV- infected leaf tissue. Three biological replicates were used for infected leaf tissue and one pooled mock-inoculated sample was used as a control/reference.

Analysis of Colletotrichum orbiculare infection of N. benthamiana

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.
