Here  we develop Nanopore three prime end capture sequencing Nano3P seq  a novel method that relies on nanopore cDNA sequencing to simultaneously quantify RNA abundance  tail composition and tail length dynamics at per read resolution. By employing a template switching based sequencing protocol  Nano3P seq can sequence any given RNA molecule from its three prime end  regardless of its polyadenylation status  without xxx need for PCR amplification or ligation of RNA adapters. We demonstrate that Nano3P seq captures a wide diversity of RNA biotypes  providing quantitative estimates of RNA abundance and tail lengths in mRNA  lncRNA  sn/snoRNA  scaRNA  and rRNA molecules. We find that  in addition to mRNA and lncRNA  polyA tails can be identified in 16S mitochondrial rRNA in both mouse and zebrafish models. Moreover  we show that mRNA tail lengths are dynamically regulated during vertebrate embryogenesis at an isoform specific level  correlating with mRNA decay. Finally  we identify non A bases within polyA tails of various lengths and reveal their distribution during vertebrate embryogenesis.
