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.

Transcriptome sequencing of transgenic Nicotiana benthamiana producing moth pheromones [2]

Project description:Insect sex pheromones are an important resource in integrated pest management. Encouraging steps have been made towards their sustainable production in plant biofactories, but important obstacles remain to be resolved. We have used transcriptomic analysis to determine the molecular perturbations behing growth penalty associated with high pheromone production in transgenic Nicotiana benthamiana lines with constitutive expression of genes for biosynthesis of moth sex pheromones - SexyPlants v1.2. We analyzed two lines with high production of pheromones as well as wt N. benthamiana.

Small RNAs from Nicotiana benthamiana leaves

Project description:Small RNA expression from Nicotiana benthamiana leaves was profiled with the primary goal of ascertaining microRNA isoform diversity for known, conserved families. A secondary goal was to provide a baseline small RNA expression atlas for this species and tissue.

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.

Identification of NMD regulated genes in Nicotiana benthamiana

Project description:Nonsense mediated decay (NMD) is a translation termination coupled quality control system. NMD identifies and degrades aberrant mRNAs containing premature termination codons, thereby preventing the accumulation of detrimental truncated proteins. NMD also controls the expression of several normal mRNAs and non-coding transcripts. RNA-seq assays were conducted to identify the NMD regulated genes in Arabidopsis. However, NMD targets have not been studied in other plants. To identify the conserved NMD targets, we wanted to identify the NMD regulated genes in Nicotiana benthamiana model species. Virus induced gene silencing was used to inactivate UPF1 NMD key factor in N. benthamiana, and then comparative RNA-seq experiment was carried out using UPF1-silenced and control–silenced plants. We found that in N. benthamiana significantly more genes are controlled by NMD than in Arabidopsis and that, surprisingly few conserved NMD targets can be recognized. These results suggest that while the mechanism of NMD is highly conserved, the set of NMD controlled genes can be quickly changed in plants.

Identification of miRNAs and Their Target Genes in juvenile Nicotiana benthamiana Plants [miRNA-Seq]

Project description:This study aims to identify and functionally characterize miRNAs and their target genes in juvenile Nicotiana benthamiana plants using miRNA sequencing (miRNA-seq) and degradome sequencing. miRNA-seq will be employed to profile the miRNA repertoire, while degradome sequencing will be used to identify miRNA-mediated mRNA cleavage sites and validate target genes. The combined approach will elucidate the regulatory roles of miRNAs in the early developmental stages of Nicotiana benthamiana and provide insights into their functional characteristics

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.
