This study identifies the BmMasc-BmPSI complex as essential for male-type Bmdsx splicing in silkworms by binding to female-specific introns and exons.

This study identifies a novel male-killing mechanism in Wolbachia that persists despite the presence of a male-killing suppressor in its host.

This study identifies two venom proteins from Asobara japonica that induce imaginal disc degradation in Drosophila, essential for parasitism success.

This study shows that the prophage-encoded Hm-oscar gene in the tea tortrix moth causes male lethality, similar to Wolbachia-induced male killing in other insects.

The paper identifies two recessive lethal mutations in semiconsomic silkworm strains, showing that deleterious mutations on a B. mandarina-derived chromosome cause embryonic lethality.

The paper identifies torimochi as an active, expanding retrotransposon in silkworm cells that produces piRNAs and may function as a dynamic piRNA cluster.

The paper investigates dosage compensation in silkworm males by analyzing allele-specific expression and finds both Z chromosomes are transcriptionally downregulated.

The paper analyzes transcriptome changes in silkworm larvae overexpressing a piRNA-resistant Masculinizer gene, finding global repression of Z-linked genes in females but minimal effect on males.

The paper identifies a mutation in the Bmmah gene, a β-group solute carrier gene, as responsible for the reddish-brown egg and eye coloration in the silkworm b-4 mutant.

This study identifies CENP-T as essential for CenH3-independent kinetochore assembly in Lepidoptera, showing its role in recruiting the Mis12 complex and supporting mitotic progression.
