Pseudouridine in small RNAs
Pseudouridine is an isomer of uridine and is the most common RNA modification in both procaryotes and eucaryotes. It is found in ribosomal, transfer, and other structural RNA as well as in some mRNA and non-coding RNA. We have found abundant pseudouridine in small RNA and their precursors in Arabidopsis.
