PRJDA48645 Identification of PIWI-interacting RNAs deriving from the silkworm W chromosome To reveal the nature of Bombyx mori W chromosome, we analyzed PIWI-interacting RNAs (piRNAs), which is known to silence transposons in the germ line cells, derived from B. mori male and female gonads with different types of W chromosome. As a result, we successfully identified piRNAs deriving from the sex-determining region of W chromosome. laboratory of Insect Genetics and Bioscience bioproject PRJDA48645 PRJDA48645 true genomeprj 48645 48645 false none provided
