Multi-omics analysis of small RNA, transcriptome and degradome of RSV-infected Nicotiana benthamiana - the regulatory networks of Nicothiana benthamiana genes in response to RSV infection
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. Overall design: Analysis of RSV-derived small RNA transcriptome and mRNA transcriptome in 6 libraries (2 treatments × 3 biological replicates); Analysis of mRNA degradome in 1 libraries (a pool of 3 biological replicates of RSV-infected Nicotiana benthamiana)
