Outline of Final Research Achievements

To investigate whether microRNAs (miRNAs) are involved in sexual development of the silkworm Bombyx mori, we performed genome wide analysis for miRNAs that are highly expressed in the sex determination stage. The analysis identified that miR-2733i-3p is specifically expressed at the sex determination stage. Knockdown of miR-2733i-3p resulted in lower expression of the sex-determining gene Bmdsx in embryonic stage. in silico analysis predicted that Bmdsx is a possible target of miR-2733i-3p. Our validation analysis with reporter assays demonstrated that miR-2733i-3p binds to a target sequence in the Bmdsx 3’UTR and repress its translation. These results suggest that miR-2733i-3p may regulate sexual development of the silkworm by regulating the expression of Bmdsx.
