  • MicroRNAs （miRNAs） are small RNAs （sRNA） that regulate post-transcriptional gene expression by cleaving or inhibiting the translation of target gene transcripts. Based on the conservation of miRNAs in many plant species and the currently available genome sequence, 10 individual conserved miRNAs have been predicted in Musa acuminata, and these miRNAs were found to belong to 8 families. Online psRNATagret software was run and 24 pairs of miRNAs were predicted to interact with their targets in Musa acuminata, and these target genes are involved in metabolism, development, response to biotic and abiotic stresses, and other cellular processes. This study has provided information on Musa acuminata miRNAs and their targets for future studies.

Abstract: MicroRNAs （miRNAs） are small RNAs （sRNA） that regulate post-transcriptional gene expression by cleaving or inhibiting the translation of target gene transcripts. Based on the conservation of miRNAs in many plant species and the currently available genome sequence, 10 individual conserved miRNAs have been predicted in Musa acuminata, and these miRNAs were found to belong to 8 families. Online psRNATagret software was run and 24 pairs of miRNAs were predicted to interact with their targets in Musa acuminata, and these target genes are involved in metabolism, development, response to biotic and abiotic stresses, and other cellular processes. This study has provided information on Musa acuminata miRNAs and their targets for future studies.
