ABSTRACT Modifications of short RNAs at specific sites can be achieved commercially by solid-phase chemical synthesis method. However, labelling long RNAs is still challenging for the routine methods. Position-selective Labelling of RNA (PLOR) is a hybrid phase transcription method that allows to label RNAs at desired sites with great flexibility and decent efficiency. In principle, PLOR is a promising method for synthesis of long modified RNAs that are unable to be generated by solid-phase chemical synthesis and other methods. However, as a recently developed method, PLOR has been only applied to label a 71nt and a 104nt RNA, and the limited sequence applications of PLOR may hinder its potential usages. To extend PLOR to more RNAs, we tested the PLOR performances for various RNA sequences. Considering that the controlled transcriptional pauses at the initiation stage in PLOR may lead to different preferences on RNA sequences from in vitro transcription method, we here focused on identifying the effects of the 5ʹ-end and initiated lengths of RNA on PLOR. In addition, our work demonstrated that PLOR efficiencies also varied with linker sizes of DNA templates. This work can facilitate PLOR to be the choice of synthesizing long modified RNAs for more users in the near future.
