This study aims at characterizing RNASET2 in the larvae of black soldier fly (BSF), <i>Hermetia illucens</i>, which are used for organic waste reduction and the production of valuable insect biomolecules for feed formulation and other applications. Given the exposure of BSF larvae to pathogens present in the feeding substrate, it is likely that the mechanisms of their immune response have undergone significant evolution and increased complexity. After in silico characterization of HiRNASET2, demonstrating the high conservation of this T2 homolog, we investigated the expression pattern of the enzyme in the fat body and hemocytes, two districts mainly involved in the insect immune response, in larvae challenged with bacterial infection. While no variation in HiRNASET2 expression was observed in the fat body following infection, a significant upregulation of HiRNASET2 synthesis occurred in hemocytes shortly after the injection of bacteria in the larva. The intracellular localization of HiRNASET2 in lysosomes of plasmatocytes, its extracellular association with bacteria, and the presence of a putative antimicrobial domain in the molecule, suggest its potential role in RNA clean-up and as an alarm molecule promoting phagocytosis activation by hemocytes.

Furthermore, leveraging the weighted gene coexpression network analysis, we observed diverse expression patterns of different Hsp types across various tissues, with certain Hsp70 showing tissue-specific bias. Noteworthy among the highly expressed Hsp genes was testis-specific, which may serve as a pivotal hub gene regulating the gene network.

In this study, two CHS genes of <i>Aedes</i> <i>albopictus</i> (<i>AaCHS1</i> and <i>AaCHS2</i>) were identified and their basic characteristics were evaluated via bioinformatics analysis. The highest abundance of <i>AaCHS1</i> transcripts was detected in pupae, whereas that of <i>AaCHS2</i> transcripts was detected in females; the highest expression levels of <i>AaCHS1</i> and <i>AaCHS2</i> were found in the epidermis and the midgut of pupae, respectively. The survival and emergence rates of pupae were significantly reduced after the injection of double-stranded RNA of <i>AaCHS1</i> or <i>AaCHS2</i>, indicating that both <i>AaCHS1</i> and <i>AaCHS2</i> play crucial roles in the pupal development. In addition, the chitin content of pupae was obviously decreased after the suppression of <i>AaCHS1</i> expression by RNA interference (RNAi) treatment. This influence of the RNAi treatment was further supported by the reduced chitin thickness and weakened chitin fluorescence signal in the new cuticle.

Through the construction of expressed sequence tag (EST) database of <i>Bombyx mori</i> from many tissues, the existence of a large number of cuticular protein (CP) genes was identified in wing disc cDNA library of the 3 days after the start of wandering (W3). From the genomic analysis, 12 types of CP clusters of CP genes were identified. DNA sequences of CP genes revealed the duplication of CP genes, which suggests to reflect the insect evolution.

The binding sites of ERTF have been reported to exist upstream of CP genes in several insects, and the activation of CP genes occurred by the binding of ERTFs. Through the analysis, the following were speculated; the successive appearance of ERTFs and the activation of target genes resulted in the successively produced CPs and cuticular layer.

This, in turn, contributes to the formulation of biologically relevant guidelines for the landscape scale transcriptome profile of organisms in lotic systems. Here, we investigated the distinct responses of seven stream stonefly species, collected from four geographical regions across Japan, to variations in temperature, including atmospheric and water temperatures. We achieved this by assessing the differences in gene expression through RNA-sequencing within individual species and exploring the patterns of community-genes among different species. We identified 735 genes that exhibited differential expressions across the temperature gradient. Remarkably, the community displayed expression levels differences of respiration and metabolic genes. Additionally, the diversity in molecular functions appeared to be linked to spatial variation, with water temperature differences potentially contributing to the overall functional diversity of genes. We found 22 community-genes with consistent expression patterns among species in response to water temperature variations. These genes related to respiration, metabolism and development exhibited a clear gradient providing robust evidence of divergent adaptive responses to water temperature. Our findings underscore the differential adaptation of stonefly species to local environmental conditions, suggesting that shared responses in gene expression may occur across multiple species under similar environmental conditions.
