Sex determination in Bombyx mori
We describe here the current status and future prospects of sex-determination studies in the silkworm, Bombyx mori. The sex of Bombyx is strongly controlled by the presence of the W chromosome. Although several classical studies suggested that a presumptive feminizing gene (Fem) is located at a limited portion of the W chromosome, the Fem gene has not yet been cloned. Recently, the homologues o...
متن کاملIdentification of Sumoylated Proteins in the Silkworm Bombyx mori
Small ubiquitin-like modifier (SUMO) modification (SUMOylation) is an important and widely used reversible modification system in eukaryotic cells. It regulates various cell processes, including protein targeting, transcriptional regulation, signal transduction, and cell division. To understand its role in the model lepidoptera insect Bombyx mori, a recombinant baculovirus was constructed to ex...
متن کاملThe genome sequence of silkworm, Bombyx mori.
We performed threefold shotgun sequencing of the silkworm (Bombyx mori) genome to obtain a draft sequence and establish a basic resource for comprehensive genome analysis. By using the newly developed RAMEN assembler, the sequence data derived from whole-genome shotgun (WGS) sequencing were assembled into 49,345 scaffolds that span a total length of 514 Mb including gaps and 387 Mb without gaps...
متن کاملBombyx mori histone methyltransferase BmAsh2 is essential for silkworm piRNA-mediated sex determination
Sex determination is a hierarchically-regulated process with high diversity in different organisms including insects. The W chromosome-derived Fem piRNA has been identified as the primary sex determination factor in the lepidopteran insect, Bombyx mori, revealing a distinctive piRNA-mediated sex determination pathway. However, the comprehensive mechanism of silkworm sex determination is still p...
متن کاملBombyx mori P-element Somatic Inhibitor (BmPSI) Is a Key Auxiliary Factor for Silkworm Male Sex Determination
Manipulation of sex determination pathways in insects provides the basis for a wide spectrum of strategies to benefit agriculture and public health. Furthermore, insects display a remarkable diversity in the genetic pathways that lead to sex differentiation. The silkworm, Bombyx mori, has been cultivated by humans as a beneficial insect for over two millennia, and more recently as a model syste...
