Molecular cloning of cDNAs encoding moricin, a novel antibacterial peptide from the silkworm (Bombyx mori), was performed using a fat-body cDNA library. A reverse-transcription PCR product encoding a partial nucleotide sequence of moricin was used as a probe. Nucleotide sequencing of four positive clones revealed two types of moricin cDNAs designated moricin 1 and 2. cDNAs for moricin 1 and 2 s...

Kokon merupakan produk yang dihasilkan oleh ulat sutera (Bombyx mori), banyak mengandung serisin membungkus filamen pada serat fibroin kokon, bobotnya 20-30% dari bobot total kokon. Serisin ini salah satu antioksidan bermanfaat mengurangi proses aging disebabkan radikal bebas. didapatkan kokon bekualitas baik maupun cacat, diharapkan dapat diformulasi menjadi sediaan serum limbah sebagi anti-ag...

Since ancient times, honey has been considered one of the most illustrious and esteemed natural products. Honey plays two key roles; specifically, it is an appreciated nutritional product, also exhibits a wide range beneficial properties for human health as therapeutic agent. Furthermore, shown that valuable effects on biological physiological features mulberry silkworms (Bombyx mori). Bombyx m...

To investigate the patterns of nucleotide diversity in domesticated silkworm, Bombyx mori L. (Lepidoptera: Bombycidae) and its wild relative, Chinese wild silkworm, Bombyx mandarina Moore, we sequenced nine nuclear genes. Neutrality test and coalescent simulation for these genes were performed to look at bottleneck intensity and selection signature; linkage disequilibrium (LD) within and betwee...

GlcNAcase is a glycosyl hydrolase located in the lysosomes of numerous organisms. Levels of the protein, β-N-acetylglucosaminidase 2 (GlcNAcase2), which is a member of the GlcNAcase family, are different in two strains of the silkworm Bombyx mori that have different resistance to Bombyx mori nucleopolyhedroviruses (BmNPVs). We identified six single-nucleotide differences in the GlcNAcase2 codin...

A rare phenomenon of SDS-induced activation of a latent protease activity associated with the purified silkworm excretory red fluorescent protein (SE-RFP) was noticed. SE-RFP aliquots incubated with SDS for different time intervals indicated that the protein undergoes an obligatory breakdown into a number of subunits which exhibit autoproteolytic (acting upon themselves) and/or heteroproteolyti...

Abstract Background 20-hydroxyecdysone (20E) plays important roles in insect molting and metamorphosis. 20E-induced autophagy has been detected during the larval–pupal transition different insects. In Bombyx mori , is induced by 20E larval fat body. Long non-coding RNAs (lncRNAs) function various biological processes many organisms, including Many lncRNAs have reported to be potential for occur...

the influence of moisture content of mulberry leaf on the growth, development and moisture build up in the body of silkworm was studied by feeding with different maturity leaves to late age of silkworm larvae. significantly higher larval moisture (79.78%), larval weight (65.65 g), pupal moisture (73.81%) was recorded in top tender leaf (high moisture) fed batches and least was recorded in the c...
