Bombyx mori nucleopolyhedrovirus Bm96 suppresses viral virulence in Bombyx mori larvae

Journal of Invertebrate Pathology, 2020
Bombyx mori nucleopolyhedrovirus (BmNPV) is a severe pathogen for the domestic silkworm, Bombyx mori. BmNPV harbors over 140 protein-coding genes in its 128.4 kilobase pair-long double-stranded genome. However, many BmNPV genes are still uncharacterized. Here we investigated the role of BmNPV Bm96 in both B. mori cultured cells and larvae.

Early embryonic development of Bombyx

Development Genes and Evolution, 2021
Decades have passed since the early molecular embryogenesis of Drosophila melanogaster was outlined. During this period, the molecular mechanisms underlying early embryonic development in other insects, particularly the flour beetle, Tribolium castaneum, have been described in more detail.

Cytopathology of the trachea of Bombyx mori (Lepidoptera: Bombycidae) to Bombyx mori nucleopolyhedrovirus

Micron, 2016
Bombyx mori is a holometabolous insect found only in germplasm banks and morphological data related of resistance and susceptibility to diseases is important when selecting hybrids for commercial and scientific interest. This study analyzed the cytopathology of B. mori trachea to BmNPV, isolated geographically in Paraná state, Brazil.

Hexosamine in Bombyx mori Silk

Nature, 1965
CONSTITUENTS other than protein in Bombyx mori silk have received little attention1. The significant amounts of hexosamine found in hair and wool2 prompted this study to quantitate and to identify the amino-sugars in B. mori silk.

Embryonic silk gland development in Bombyx : molecular cloning and expression of the Bombyx trachealess gene

Development Genes and Evolution, 1999
We describe embryonic development of the Bombyx silk gland. To extend the analysis further we isolated a Bombyx counterpart gene of the Drosophila trachealess (trh) gene. Bombyx trh encodes a protein of 849 amino acids. When compared with the amino acid sequence of Drosophila trh, the identity of Bombyx bHLH, PAS-A and PAS-B domains is 100%, 97%, and ...

Neuropeptides of the silkworm,Bombyx mori

Experientia, 1992
Six neuropeptides of the silkworm, Bombyx mori, have been isolated and chemically characterized during the past 10 years. They are bombyxin, prothoracicotropic hormone, pheromone-biosynthesis-activating neuropeptide/melanization-and-reddish-coloration hormone, diapause hormone, eclosion hormone, and adipokinetic hormone.

Comparative transcriptome analysis of wing discs from Bombyx mori and Bombyx mandarina

Journal of Asia-Pacific Entomology, 2020
Abstract The insect wing is developed from the wing imaginal disc which is designed from the embryonic ectoderm. To get insight into gene expression profiles in wing discs of Bombyx mori during metamorphosis, we compared the gene expression in the wing between B. mori and B. mandarina moth through RNA-seq. Out of total valid reads identified from the

Bombyx small RNAs: Genomic defense system against transposons in the silkworm, Bombyx mori

Insect Biochemistry and Molecular Biology, 2008
Selfish genetic elements called transposons can insert themselves at new locations in host genomes to modify gene structure and alter gene expression. Expansion of transposons can occur when novel transposition events are transmitted to subsequent generations after germline hopping. Therefore, organisms seem likely to have evolved defense mechanisms to

Bombyx EcR (BmEcR) and Bombyx USP (BmCF1) combine to form a functional ecdysone receptor

Insect Biochemistry and Molecular Biology, 1996
The Drosophila ecdysone receptor (DmEcR) is a member of the nuclear receptor superfamily; it functions as an obligate heterodimer with another nuclear receptor, DmUSP. EcR homologs have now been cloned from several other insects. We report here that one such homolog, BmEcR from the commercial silkmoth, Bombyx mori, is a functional ecdysone receptor ...

Novel microRNAs in silkworm (Bombyx mori)

Functional & Integrative Genomics, 2010
We acquired more than 4 million useful sequences using a high-throughput method from a library for miRNA identification, which is constructed from a mixture of 14 RNA samples from different developmental stages. We mapped 247,410 reads to known silkworm miRNAs in miRBase (13.0), 701,913 reads to other RNA molecules based on sequence homology, and 3,219,
