The genome of the model beetle and pest Tribolium castaneum
Tribolium castaneum is a member of the most species-rich eukaryotic order, a powerful model organism for the study of generalized insect development, and an important pest of stored agriculturalExpand
Identification of G protein-coupled receptors for Drosophila PRXamide peptides, CCAP, corazonin, and AKH supports a theory of ligand-receptor coevolution
TLDR
Two groups of GPCRs predicted as receptors for peptides with a C-terminal amino acid sequence motif consisting of −PRXamide (PRXa) are characterized and support a theory of coevolution for NMU and Drosophila PRXa peptides and their respective receptors. Expand
A protein from the salivary glands of the pea aphid, Acyrthosiphon pisum, is essential in feeding on a host plant
TLDR
It is shown, by using RNAi-based transcript knockdown, that this protein is important in the survival of the pea aphid (Acyrthosiphon pisum) on fava bean, a host plant, and this protein, whose sequence contains an N-terminal secretion signal, is injected into the host plant during aphid feeding. Expand
Deletion of the ecdysis-triggering hormone gene leads to lethal ecdysis deficiency.
TLDR
It is shown that deletion of eth, the gene encoding ETH in Drosophila, leads to lethal behavioral and physiological deficits, and obligatory roles for eth and its gene products in initiation and regulation of the ecdysis sequence are established. Expand
RNAi Knockdown of a Salivary Transcript Leading to Lethality in the Pea Aphid, Acyrthosiphon pisum
TLDR
Injection of siRNA into parthenogenetic adult pea aphids is shown to lead to depletion of a target salivary gland transcript, which suggests that siCoo2-RNA injections can be a useful positive control in such studies. Expand
Genomics, transcriptomics, and peptidomics of neuropeptides and protein hormones in the red flour beetle Tribolium castaneum.
TLDR
The authors' analysis of Tribolium indicates that, during insect evolution, genes for neuropeptides and protein hormones are often duplicated or lost. Expand
A genome-wide inventory of neurohormone GPCRs in the red flour beetle Tribolium castaneum
TLDR
The survey of 340 million years of insect neurohormone GPCR evolution shows that neuropeptide/receptor couples can easily duplicate or disappear during insect evolution and shows that Drosophila is not a good representative of all insects, because several of the hormonal systems that the authors now find in Tribolium do not exist in Dosophila. Expand
Corazonin receptor signaling in ecdysis initiation.
TLDR
Findings support the role of corazonin signaling in initiation of the ecdysis behavioral sequence and propose a model for peptide-mediated interactions between Inka cells and the CNS underlying this process in insect development. Expand
BeetleBase in 2010: revisions to provide comprehensive genomic information for Tribolium castaneum
TLDR
BeetleBase has been updated to provide more comprehensive genomic information for the red flour beetle Tribolium castaneum, and the BLAST and BLAT search tools have been integrated with the GMOD tools. Expand
Uncovering the novel characteristics of Asian honey bee, Apis cerana, by whole genome sequencing
TLDR
This first report of the whole genome sequence of A. cerana provides resources for comparative sociogenomics, especially in the field of social insect communication, to contribute to a better understanding of the complex behaviors and natural biology of the Asian honey bee and to anticipate its future evolutionary trajectory.
