PIWI-interacting RNAs (piRNAs) guide PIWI proteins to target transposons in germline cells, thereby suppressing transposon activity to preserve genome integrity in metazoans' gonadal tissues. Piwi, one of three Drosophila PIWI proteins, is expressed

Bacterial symbionts, such as Wolbachia species, can manipulate the sexual development and reproduction of their insect hosts. Here, the authors identify a Wolbachia protein that interacts with a host masculinization factor and leads to male killing i

PIWI proteins and PIWI-interacting RNAs (piRNAs) play a central role in repressing transposable elements in animal germ cells. It is thought that piRNAs are mainly produced from discrete genomic loci named piRNA clusters, which often contain many "de

Bombyx mori densovirus 1 (BmDV1) is a pathogen that causes flacherie disease in mulberry silkworms (B. mori). The absolute resistance (non-susceptibility) to BmDV1 of certain silkworm strains is determined independently by two genes, nsd-1 and Nid-1.

Mature piRNAs are produced from long single-stranded precursor RNAs. Here the authors show that RNase κ generates 2′,3′-cyclic phosphate-containing piRNA precursors and promotes piRNA production.

The Masculinizer (Masc) gene encodes a CCCH‐tandem zinc finger protein that controls both masculinization and dosage compensation in the silkworm Bombyx mori. We previously measured the masculinizing activity of the lepidopteran Masc proteins using

Abstract Bombyx mori densovirus type 1 (BmDV) is a pathogen that causes flacherie disease in the silkworm. The absolute nonsusceptibility to BmDV among certain silkworm strains is determined independently by two genes, nsd-1 and Nid-1. However, neith

The white color in the larval integument of the silkworm Bombyx mori is considered the result of uric acid accumulation in its epidermal cells. Larvae of the eri silkworm Samia ricini (Lepidoptera; Saturniidae) also have a white and opaque integument

The Bombyx mori latent virus (BmLV) belongs to the unassigned plant virus family Tymoviridae and contains a positive-sense, single-stranded RNA genome. BmLV has infected almost all B. mori-derived cultured cell lines through unknown routes. The sourc

In Bombyx mori (B. mori), Fem piRNA originates from the W chromosome and is responsible for femaleness. The Fem piRNA-PIWI complex targets and cleaves mRNAs transcribed from the Masc gene. Masc encodes a novel CCCH type zinc-finger protein and is req
