Transcriptome Analysis Reveals the Gene Expression Changes in the Silkworm (Bombyx mori) in Response to Hydrogen Sulfide Exposure

Hydrogen sulfide (H2S) has been recognized for its beneficial influence on physiological alterations. The development (body weight) and economic characteristics (cocoon weight, cocoon shell ratio, and cocoon shell weight) of silkworms were increased after continuous 7.5 µM H2S treatment. In the present study, gene expression changes in the fat body of silkworms at the 5th instar larvae in response to the H2S were investigated through comparative transcriptome analysis. Moreover, the expression pattern of significant differentially expressed genes (DEGs) at the 5th instar larvae was confirmed by quantitative real-time PCR (qRT-PCR) after H2S exposure. A total of 1200 (DEGs) was identified, of which 977 DEGs were up-regulated and 223 DEGs were down-regulated. Most of the DEGs were involved in the transport pathway, cellular community, carbohydrate metabolism, and immune-associated signal transduction. The up regulated genes under H2S exposure were involved in endocytosis, glycolysis/gluconeogenesis, the citrate cycle (TCA cycle), and the synthesis of fibroin, while genes related to inflammation were down-regulated, indicating that H2S could promote energy metabolism, the transport pathway, silk synthesis, and inhibit inflammation in the silkworm. In addition, the expression levels of these genes were increased or decreased in a time-dependent manner during the 5th instar larvae. These results provided insight into the effects of H2S on silkworms at the transcriptional level and a substantial foundation for understanding H2S function.

INTERNAL QUALITIES OF EGG(S) OF LAYING BIRDS FED DIETS CONTAINING VERNONIAAMYGDALINALEAF (BITTER LEAF) MEAL AT DIFFERENT GROWING PHASES

One hundred and twenty eight Isa-Brown pullet chicks were used for this study to determine the internal qualities of egg(s) from birds fed diets containing Vernoniaamygdalina leaf meals at different growing phases. The leaves used were air-dried, crushed and milled, and was then incorporated into the experimental treatments (T2, T3, and T4) at 2% inclusion each. The birds were randomly allotted into four dietary treatments (T1, T2, T3 and T4) and each treatment was replicated four times with each replicate having 8 birds from the chick phase to the growing phase, thereafter 6 birds per replicate were randomly picked at the laying phase (point of cage), with T1 serving as the control treatment throughout the experimental period of 39weeks. The parameters measured include egg weight, shell weight, shell thickness, shell height, yolk weight, yolk height, yolk width, albumin length, albumin height, albumin weight, while yolk index and Haugh unit were calculated. The result of the experiment showed that T3 with 2% inclusion of Vernoniaamygdalinafrom the growing phase had the best shell thickness, yolk color and acceptable value for Haugh unit. Other parameters measured showed that yolk weight, and Haugh unit were significant at (p<0.05) with 2% inclusion of Vernoniaamygdalina. Every other parameter measured showed no significant difference across the treatments at (p>0.05). The result showed that 2% inclusion of Vernoniaamygdalinaleaf meal at the growing phase of the experiment improved the internal qualities of eggs.

A Cluster of Genes at the Terminal Region of Chromosome 1 Contributes to Silk Yield in Bombyx Mori.

Background: The silk yield is the most economically important trait in sericulture. In the domestication of the silkworm, traits related to silk yield are the main selective targets. In previous studies, linkage and association analyses were performed, which narrowed the region of the locus controlling the cocoon shell weight (CSW), an important index of silk yield, to the interval of 0–134 kb on the 1st chromosome. Results In this study, selection pressure analysis showed that most of the loci in this interval were co-selected during silkworm domestication. Association analysis conducted with 95 strains found that there is a 110 kb region that was significantly associated with CSW. An expression profile correlation analysis of eight genes in the region showed that their expression patterns were very similar. Sequence variation analysis detected mutations in the exon regions of BMgn002066 and BMgn002073, leading to premature termination of translation. The sequence variation was significantly correlated with CSW. In addition, another two genes, BMgn002067 and BMgn002071, had significantly different expression levels in the posterior silk glands of 11 high-yield strains and 11 low-yield strains. Therefore, we speculate that the abovementioned four genes and the gene BmAbl1 detected in previous studies may co-regulate CSW. Conclusions This study is the first to identify the gene clusters that affect CSW by forward genetics, thereby providing new evidence for gene clusters that regulate quantitative traits.

The effect of feeding various species of mulberry (Morus spp.) on the growth of silkworm and quality of cocoon hybrid BS 09

Hybrid silkworm varieties, mulberry species, environmental factors, and rearing factors are essential for the cocoons’ quality. The species of silkworm feeding is a key factor in the sericulture industry, so the suitability of mulberry species for each silkworm hybrid species needs to be known. This study aimed to determine the effect of mulberry species on silkworm growth and quality of cocoons BS 09. The research method used was a randomized block design with four species of mulberry: Morus bombycis var Lembang, M. cathayana, M. multicaulis, and M. alba var Kanva 2 and one control species (mixed mulberry species). The research was carried out at Dramaga Research Forest, Bogor Regency. The determined parameters were the percentage of rearing, larva weight, cocoon weight, cocoon shell weight, and percentage of cocoon shell. The experiment results showed that the percentage of rearing was 97.5%-100% for all species of mulberry. The best result of the cocoon weight was feed treatment of M. multicaulis (1.89 g), but it was not significant with feed treatment of M. bombycis var Lembang or M. cathayana or M. alba var Kanva 2. M. cathayana feed treatments give the best results for the cocoon shell weight (0.44 gram) and percentage of cocoon shell (22.82%).
