Project description:One of the most thoroughly studied insect species, with respect to locomotion behaviour, is the stick insect Carausius morosus. Although detailed information exists on premotor networks controlling walking, surprisingly little is known about neuropeptides, which are certainly involved in motor activity generation and modulation. So far, only few neuropeptides were identified from C. morosus or related stick insects. We performed a transcriptome analysis of the central nervous system to assemble and identify 65 neuropeptide and protein hormone precursors of C. morosus, including five novel putative neuropeptide precursors without clear homology to known neuropeptide precursors of other insects (Carausius neuropeptide-like precursor 1, HanSolin, PK-like1, PK-like2, RFLamide). Using Q Exactive Orbitrap and MALDI-TOF mass spectrometry, 277 peptides including 153 likely bioactive mature neuropeptides were confirmed. Peptidomics yielded a complete coverage for many of the neuropeptide propeptides and confirmed a surprisingly high number of heterozygous sequences. Few neuropeptide precursors commonly occurring in insects, including those of insect kinins and sulfakinins, could neither be found in the transcriptome data nor did peptidomics support their presence. The results of our study represent one of the most comprehensive peptidomic analyses on insects and provide the necessary input for subsequent experiments revealing neuropeptide function in greater detail.

Project description:Food resource access can mediate establishment success in invasive species, and generalist herbivorous insects are thought to rely on mechanisms of transcriptional plasticity to respond to dietary variation. While asexually reproducing invasives typically have low genetic variation, the twofold reproductive capacity of asexual organisms is a marked advantage for colonization. We studied host-related transcriptional acclimation in parthenogenetic, invasive, and polyphagous weevils: Naupactus cervinus and N. leucoloma. We analyzed patterns of gene expression in three gene categories that can mediate weevil-host plant interactions through identification of suitable host plants, short-term acclimation to host plant defenses, and long-term adaptation to host plant defenses and their pathogens. This approach employed comparative transcriptomic methods to investigate differentially expressed host detection, detoxification, immune defense genes, and pathway-level gene set enrichment. Our results show that weevil gene expression responses can be host plant-specific, and that elements of that response can be . Some host plant groups, such as legumes, appear to be more taxing as they elicit a complex gene expression response which is both strong in intensity and specific in identity. However, the weevil response to taxing host plants shares many differentially expressed genes with other stressful situations, such as host plant cultivation conditions and transition to novel host, suggesting that there is an evolutionarily favorable shared gene expression regime for responding to different types of stressful situations. Modulating gene expression in the absence of other avenues for phenotypic adaptation may be an important mechanism of successful colonization for these introduced insects.

Project description:Here we report the derivation of human haploid ESCs from parthenogenetic haploid embryos. We used RNA-seq to compare the gene expression levels among human parthenogenetic haploid ESCs (hPGES), normal human ESCs (H9) and human forskin fibroblasts and identified that these cells express conventional ESCs pluripotent markers and most maternally imprinted genes were down-regulated.
