High throughput sequencing revolution reveals conserved fundamentals of U-indel editing.

ABSTRACT: Among Euglenozoans, mitochondrial RNA editing occurs in the diplonemids and in the kinetoplastids that include parasitic trypanosomes. Yet U-indel editing, in which open reading frames (ORFs) on mRNAs are generated by insertion and deletion of uridylates in locations dictated by guide RNAs, appears confined to kinetoplastids. The nature of guide RNA and edited mRNA populations has been cursorily explored in a surprisingly extensive number of species over the years, although complete sets of fully edited mRNAs for most kinetoplast genomes are largely missing. Now, however, high throughput sequencing technologies have had an enormous impact on what we know and will learn about the mechanisms, benefits, and final edited products of U-indel editing. Tools including PARERS, TREAT, and T-Aligner
