Heavy metal pollution in the environment is mostly manifested as a multi-elemental compound pollution. The effect of long-term exposure to heavy on gut microbes insects has remained unknown. For current work, population Eucriotettix oculatus living mining areas around Diaojiang River with history hundreds years pollution, was selected along similar species non-mining conduct comparative study their microbes. microbial communities were analyzed using 16S rRNA amplicon sequencing. results...
The gut microbiome significantly influences the health and productivity of silkworms (
The pygmy grasshoppers, which belong to the superfamily Tetrigoidea, exhibit remarkable environmental adaptability. However, no study has yet reported a reference genome for this group. In study, we assembled high-quality chromosome-scale of Eucriotettix oculatus, survive in environment heavily polluted by heavy metals, achieved through Illumina and PacBio sequencing, alongside chromosome conformation capture techniques. resulting spans 985.45 Mb across seven chromosomes (range: 71.55 266.65...
Scelimeninae is a key member of the pygmy grasshopper community, and an important ecological indicator. No mitochondrial genomes have been reported to date, monophyly its phylogenetic relationship within Tetrigidae still unclear. We sequenced analyzed eight nearly complete representing genera Scelimeninae. These mitogenomes ranged in size from 13,112 16,380 bp order tRNA genes between COII ATP8 was reversed compared with ancestral insects. The protein-coding (PCGs) tetrigid species mainly...
The gut microbiota, a complex ecosystem integral to host wellbeing, is modulated by environmental triggers, including exposure heavy metals such as chromium. This study aims comprehensively explore chromium-induced microbiota and metabolomic shifts in the quintessential lepidopteran model organism, silkworm (Bombyx mori). research deployed 16S rDNA sequence analysis LC/MS metabolomics its experimental design, encompassing control group alongside low (12 g/kg) high (24 feeding chromium dosing...
Chromium is a severe heavy metal pollutant with significant environmental risks. The effects of on the digestion Bombyx mori (silkworms) are particular importance due to their ecological and economic significance. Herein, RNA sequencing was conducted nine midgut samples from silkworms exposed control, 12 g/kg 24 chemical diets. Comparative transcriptomics revealed that under moderate exposure, there increase in up-regulated genes (1268 857 down-regulated), indicating stimulation response. At...
Copper-based pesticides are extensively used in agriculture, yet their impacts on beneficial insects remain poorly understood. Here, we investigate how cupric chloride exposure affects the gut microbiome of Bombyx mori, a model organism crucial for silk production. Using 16S rRNA sequencing, analyzed bacterial communities fifth-instar silkworm larvae exposed to different concentrations (0, 4, and 8 g/kg) an artificial diet. The high-dose dramatically altered microbial diversity community...
The nearly complete mitochondrial genome (mitogenome) of Teredorus nigropennis was determined and analyzed. This mitogenome 14,652 bp in size encoded 13 protein-coding genes, two ribosomal RNA 22 transfer genes. most common start codon is ATN, the termination TAA genes have incomplete T (TA). overall nucleotide composition 45.2% A, 10.2% G, 28.6% T, 16.1% C. data will increase basic information Tetrigidae phylogenetic research can help to better understand status T. Tetrigiodea.
Parantica aglea (Lepidoptera: Nymphalidae: Danainae) was the type species of genus Parantica. In this study, complete mitochondrial genome (mitogenome) P. (GenBank accession No. MN938921) sequenced using polymerase chain reaction (PCR) method. Its mitogenome a circular molecule 15,214 bp in length, containing 13 protein-coding genes, two ribosomal RNAs, 22 transfer and one AT-rich region. The A + T content overall base composition H-strand 79.6%. All genes were begun with typical start codon...
The complete mitochondrial genome (mitogenome) of Polygonia c-aureum, from Yizhou China, is a circular molecule 15,202 bp in length, containing 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer and control region. A + T content the overall base composition 80.6%. All PCGs are begun with ATN (one ATC, four ATT seven ATG) as start codon except cox1 using CGA. Ten genes terminated TAA stop codon, cox2, nad4 nad5 end an incomplete (T). newly sequenced mitogenome will increase basic...
The complete mitochondrial genome of Appias albina (Lepidoptera: Pieridae) was firstly sequenced and characterized in our study. total length mitogenome is 15,193 bp contains 13 protein-coding genes, 2 ribosomal RNA 22 transfer 1 A + T-rich region. overall nucleotide composition 38.4% A, 8.0% G, 40.9% T, 12.4% C. Phylogenetic tree reconstructed using Bayesian Inference (BI) to validate the taxonomic status A. albina, exhibiting close relationship with remedios.
The nearly complete mitochondrial genome (mitogenome) of Lethe confuse was sequenced and analyzed. This mitogenome is 14,945 bp in size encodes 13 protein-coding genes, 22 transfer RNA 2 ribosomal genes. most common start codon ATN (ATA, ATG, ATT), the termination TAA. In addition, three PCGs have incomplete T. overall nucleotide composition 38.0% A, 7.8% G, 42.4% T, 11.8% C. data will increase basic information Satyrinae phylogenetic research can help to better understand status L. Nymphalidae.
