An improved terminal ribose-modified small RNA sequencing (TRM-sRNA-seq) reveals novel features of miRNA modification and identifies HEN1-independent 2’-O-modified sRNAs derived from tRNAs
Non-coding RNA profiling by high throughput sequencing
Summary
Concomitant cloning of RNA degradation products is a major issue in standard small RNA-sequencing practices. It not only adds complexity in bona fide sRNA characterization, but also affects experimental replicability and sometimes results in library construction failure. Given that all kinds of canonical plant small RNAs bearing the 3’ end 2’-O-methylation modification, we here developed an sRNA-seq method (named terminal ribose-modified sRNA sequencing, TRM-sRNA-seq).
Overall design
TRM-sRNA-seq relied on the sequential treatment of RNA samples with PBA-PAGE and NaIO4 oxidation.
