Fundamental and applied studies of silkworms have entered the functional genomics era. Here, we report a multi-gene expression system (MGES) based on 2A self-cleaving peptide (2A), which regulates the simultaneous expression and cleavage of multiple gene targets in the silk gland of transgenic silkworms. First, a glycine-serine-glycine spacer (GSG) was found to significantly improve the cleavag...

The silkworm, Bombyx mori, uses a complex olfactory system to determine whether the food is edible. As an odor degrading enzyme, UDP-glycosyltransferase (UGT) participates in degradation of molecules silkworm. By sequencing whole genome silkworm NB and using comparative genomics methods, we found that UGT46A1 unique species eat mulberry leaves. Bioinformatics shows its function may be related f...

In the present study, we examined whether microorganisms collaterally ingested by insects with their food activate the innate immune system to confer systemic resistance against subsequent bacterial invasion. Silkworms orally administered heat-killed Pseudomonas aeruginosa cells showed resistance against intra-hemolymph infection by P. aeruginosa. Oral administration of peptidoglycans, cell wal...

The Samarinda silk sarong is a typical made using imported yarn raw materials from China. Quality mulberry plants are needed to support silkworm cultivation (sericulture). obtained by in vitro propagation techniques. purpose of this study was determine the differences quality cocoons and threads feeding cuttings. research stages consisted rearing silkworms, handling spinning. results showed tha...

Sericigenous insects like silkworm possess an effective immune system against pathogens. The knowledge on the immune system of these insects implicating the mechanism of resistance to diseases is mainly attributable to the presence of key biomolecules such as an inducible proteins viz., cecropin, attacin, lebocin, moricin and isoforms of enzymes viz., carboxyl esterase and prophenoloxidase whic...

This study aims to determine the growth of catfish (Clarias sp.) Seeds by giving a combination silkworms (Tubifex and commercial feed. research was conducted in August - October 2020 fish farming group PT ASABRI, West Ilir II Palembang, South Sumatera. The treatments used this were 100% silkworm (control) feeding feed treatment consisting 75% 25% silkworms. Parameters include absolute weight gr...
