A major endogenous glycosidase mediating quercetin uptake in Bombyx mori

The paper identifies LQGH1, a glycosidase in Bombyx mori that mediates quercetin uptake by deglycosylating quercetin glycosides, and shows its conservation and role in silk production.

Disruption of a BTB-ZF transcription factor causes female sterility and melanization in the larval body of the silkworm, Bombyx mori

This paper identifies Bmmamo as the gene responsible for the dilute black (bd) phenotype in silkworms, linking it to female sterility and larval pigmentation.

Deleterious mutations in a heterozygous chromosome result in recessive lethality in silkworm semiconsomic strains

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