Quercetin is a common plant flavonoid which involved in herbivore–plant interactions. Mulberry silkworms (domestic silkworm, Bombyx mori , and wild mandarina ) take up quercetin from mulberry leaves accumulate the metabolites cocoon, thereby improving its protective properties. Here we identified glycoside hydrolase, named hydrolase family 1 group G 5 (GH1G5), expressed midgut metabolism domestic silkworm. Our results suggest that this enzyme mediates uptake by deglycosylating three primary...

Recent studies have suggested that ABC transporters are the main receptors of Cry toxins. However, many toxins not been identified. In this study, we used a heterologous cell expression system to identify Bombyx mori transporter subfamily C members (BmABCCs) function as for five active in Lepidopteran insects: Cry1Aa, Cry1Ca, Cry1Da, Cry8Ca, and Cry9Aa. All can use multiple ABCCs low-efficiency receptors, which induce cytotoxicity only at high concentrations. Surface plasmon resonance...

The silkworm (Bombyx mori) is an important lepidopteran model insect and industrial domestic animal traditionally used for silk production. Here, we report the genome assembly of improved Japanese strain Nichi01, in which cocoon yield comparable to that commercial strains. integration PacBio Sequel II long-read ddRAD-seq-based high-density genetic linkage map achieved highest quality silkworms date; 22 28 pseudomolecules contained telomeric repeats at both ends, only four gaps were present...

In general, transgenesis efficiency is largely dependent on the developmental status of eggs for microinjection. We investigated whether relationship between and cooling in silkworms,

Abstract Quercetin is a common plant flavonoid that involved in herbivore–plant interactions. Mulberry silkworms (domestic silkworm, Bombyx mori , and wild mandarina ) uptake quercetin from mulberry leaves accumulate the metabolites cocoon, thereby improving its protective properties. Here we identified characterized glycosidase, named LPH-like glycoside hydrolase 1 (LQGH1), initiates metabolism domestic silkworm. LQGH1 expressed midgut where it mediates by deglycosylating three most...
