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

Project description:Rice stripe virus (RSV) causes the general chlorosis symptom and influences expression of numberous chloropalst-related genes at transcriotional level in Nicotiana benthamiana plants, but the mechanism are not well understood. Small RNAs (sRNAs), including virus-derived siRNA (vsiRNA) play roles in modulating genes expression post-transcriptionally. This present work presents multi-omics analysis of the transcriptome, sRNAome and degradome in RSV-infected N.benthamiana plants. Transcriptome-seq profiled 4127 N. benthamiana genes, with differentially expressed genes (DEGs) enriched in functional categories such as metabolic process, protein phosphorylation, regulation of transcription, carotenoid biosynthetic process. We identified 400863, 203874 and 244713 reads of vsiRNA from 3 sRNA libraries of RSV-infected N.benthamiana plants respectively. The degradome-seq report discovered a significant number of N.benthamiana genes that might be regulated by vsiRNAs post-transcriptionally. Based on integrated analysis of the three omics, we provide a substantial amount of novel information on the transcriptional and post-transcriptional networks in RSV-infected N.benthamiana, which will extends our horizon about the interactions between virus and their hosts.
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.
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.
