Small RNAs from Nicotiana benthamiana leaves


ABSTRACT: 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. Two biological replicates of leaves from growth-room grown plants. The two libraries were each run twice on different runs, so there are a total of four datasets. For most analyses, it will be appropriate to combine the run1 and run2 versions for the libraries.

MicroRNAs (miRNAs) guide RNA-induced silencing complexes to target RNAs based on miRNA-target complementarity. Using a dual-luciferase based sensor system in Nicotiana benthamiana, we quantitatively assessed the relationship between miRNA-target complementarity and silencing efficacy measured at both the RNA and protein levels, using several conserved miRNAs and their known target sites from Arabidopsis thaliana. We found that naturally occurring sites have variable efficacies attributable to th  ...[more]
