Transcriptome sequencing to unravel the molecular mechanisms underlying the cuticle liquefaction of Antheraea pernyi following Antheraea pernyi nucleopolyhedrovirus challenge

ABSTRACT: Purpose: The goal of this study is to analyze the transcriptome profile changes of the cuticles between ApNPV-infected and non-infected A. pernyi larvae for investigating themolecular mechanisms of cuticle liquefaction of A. pernyi induced by ApNPV infection. Methods:The A. pernyi cuticles infected by ApNPV and normal samples were generated by deep sequencing, in triplicate, using Illumina Hiseq 4000. The high-quality reads were obtained by removing the reads that contained adaptor contamination, low quality bases and undetermined bases.The transcriptome were de novo assembly. Results:The RNA-seq data generated 57332226, 48859400, 50197630 and 52086538, 52447736, 47585326 raw reads from ApNPV-infected and control groups, respectively. After data filtering, 55715544, 48130252, 49354556, 51102012, 51633978, 46798094 clean reads were obtained (Table1). Using the Trinity de novo assembly programme, all short-read sequences were assembled into 87036 transcripts and 50126 unigenes. Conclusions:We systematically analyzed the gene expressional profiles and obtained both up- and down-regulated genes in ApNPV-infected cuticle compared with control. Meanwhile, we screened the chitin metabolism-related differentially expressed genes (DEGs) from the transcriptome data, and further characterized those DEGs based on their expression profiles challenged by ApNPV. Our research findings lay the foundation for further research on the molecular mechanisms of liquefaction induced by viral infection in insect.

The Daphnia cuticle proteome - whole cuticle samples

Project description:The cuticles of arthropods, including aquatic crustaceans like Daphnia, provide an interface between the organism and its environment. Thus, the cuticle’s structure influences how the organism responds to and interacts with its surroundings. Here, we used label-free quantification proteomics to provide a proteome of the molted cuticle of Daphnia magna, which has long been a prominent subject of studies on ecology, evolution, and developmental biology, anddetected 278 high confidence proteins. Using protein sequence domain and functional enrichment analyses, we identified chitin-binding structural proteins and chitin modifying enzymes as most abundant protein groups in the cuticle proteome.Structural cuticular protein families showed a similar distribution to those found in other arthropods and indicated proteins responsible for the soft and flexible structure of the Daphnia cuticle . Finally, cuticle protein genes were clustered as tandem gene arrays in the Daphnia genome, indicating their importance for adaptation to environmental change. The cuticle proteome presented here will be a valuable resource to the Daphnia research community, informing investigations on diverse topics such as the genetic basis of interactions with predators and parasites.

Expression profile of cuticular genes of silkworm, Bombyx mori

Project description:Insect cuticle plays essential roles in multiple physiological functions. During molting and metamorphosis, tremendous changes occur in silkworm cuticles. Silkworm is a model of Lepidoptera insects; however, little is known about the stage expression profiles of genes in cuticles of silkworm. In the present study, we selected 16 developmental stages, ranging from day 1 of the first instar larvae to day 8 of pupae, to perform microarray-based expression profiles. The data told us that various functions and physiological pathways were activated in the cuticle. Moreover, the expression profiles of cuticular protein genes, as the important components of cuticle, were investigated. The current study provides important insights for the functional study of insect cuticle and the regulation of insect cuticular protein genes.

Catharanthus Transcriptome and Gene Expression

Project description:In this study, we aim to present a global transcriptome analysis of medicinal plant, Catharanthus roseus. We generated about 343 million high-quality reads from three tissues (leaf, root and flower) using Illumina platform. We performed an optimized de novo assembly of the reads and estimated transcript abundance in different tissue samples. The transcriptome dynamics was studied by differential gene expression analyses among tissue samples. We collected different tissue samples from the mature plants. Total RNA isolated from these tissue samples was subjected to Illumina sequencing. The sequence data was further filtered using NGS QC Toolkit to obtain high-quality reads. The filtered reads were used for de novo assembly optimization. The reads were further mapped to the Catharanthus transcripts via CLC Genomics Workbench and differential gene expression analysis was performed using DESeq software.
