MicroRNAs (miRNAs) are a class of small RNAs, evolutionarily conserved endogenous non-coding RNAs that regulate their target mRNA expression by either inactivating or degrading mRNA genes; thus playing an important role in the growth and development of an organism. Maruca vitrata is an insect pest of leguminous plants like pigeon pea, cowpea and mung bean and is pantropical. In this study, we perform BLAST on all known miRNAs against the transcriptome data of M. vitrata and thirteen miRNAs were identified. These miRNAs were characterised and their target genes were identified using TargetScan and were functionally annotated using FlyBase. The importance of the structure of pre-miRNA in the Drosha activity led to study the backbone torsion angles of predicted pre-miRNAs (mvi-miR-9751, mvi-miR-649-3p, mvi-miR-4057 and mvi-miR-1271) to identify various nucleotide triplets that contribute to the variation of torsion angle values at various structural motifs of a pre-miRNA.
