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.

Heat- and wound-responsive genes in Nicotiana benthamiana

Project description:Nicotiana benthamiana is a widely used organism for expression of foreign proteins. To increase protein abundance, overexpression promoters have been developed. However, several proteins cause negative effects on plant growth and development when they are overexpressed. Therefore, overexpression promoters cannot be widely used to generate transgenic plants that produce foreign proteins. In this study, we tried to find stress-inducible promoters which specifically express downstream genes when plants were exposed to stress conditions. By RNA-sequencing analysis of heat- and wound-treated plants, we found that NbHSP20 promoters can be used as a heat-inducible promoters to express foreign proteins in 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.

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.
