Conservation-independent identification of novel miRNAs

ABSTRACT: Motivation: MicroRNAs (miRNAs) are short regulatory RNAs derived from a longer precursor RNA. miRNA biogenesis has been studied in animals and plants, recently elucidating more diverse and complex aspects, such as non-conserved, speciesspecific, and heterogeneous miRNA precursor populations. Small RNA sequencing data can be used to computationally determine genomic loci of miRNA precursors. The challenge is to predict a valid miRNA precursor from inhomogeneous read coverage: while the mature miRNA typically produces hundreds of sequence reads, the remaining part of the precursor is covered very sparsely. Results: We introduce a new conservation-independent method for the identification of miRNA precursors, that allows for speciesspecific heterogeneous precursor populations. The algorithm r
