This first time that a dual host-symbiont transcriptome sequencing effort has been conducted in a single termite species demonstrates that phenoloxidase activities are prominent in the R. flavipes gut and are not symbiont derived, and expands the known number of host and symbionT glycosyl hydrolase families in Reticulitermes.
RNA interference in the termite Reticulitermes flavipes through ingestion of double-stranded RNA.
Correlation of cellulase gene expression and cellulolytic activity throughout the gut of the termite Reticulitermes flavipes.
MAPK Signaling Pathway Alters Expression of Midgut ALP and ABCC Genes and Causes Resistance to Bacillus thuringiensis Cry1Ac Toxin in Diamondback Moth
A crucial role for ALP and ABCC genes in field-evolved resistance to Cry1Ac is highlighted and a novel trans-regulatory signaling mechanism responsible for modulating the expression of these pivotal genes in P. xylostella is revealed.
Social exploitation of hexamerin: RNAi reveals a major caste-regulatory factor in termites.
It is found that the two hexamerin proteins, which are inducible by the morphogenetic juvenile hormone and which constitute a significant proportion of total termite protein, suppress juvenile-hormone-dependent worker differentiation to the soldier caste phenotype, thus apparently enhancing colony-inclusive fitness.

In this study, expression profiles of eight candidate reference genes from the diamondback moth, Plutella xylostella, were evaluated under diverse experimental conditions and no single universal reference gene was identified.
The Architecture and Complete Sequence of Mitochondrial Genome of an Assassin Bug Agriosphodrus Dohrni (Hemiptera: Reduviidae)
Comparative analysis with two other reduviid species Triatoma dimidiata and Valentia hoffmanni exhibited highly conserved genome architectures including genome contents, gene order, nucleotide composition, codon usage, amino acid composition, as well as genome asymmetry.
Production and characterization of a recombinant beta-1,4-endoglucanase (glycohydrolase family 9) from the termite Reticulitermes flavipes.
These findings provide a foundation on which to begin subsequent investigations of collaborative digestion by coevolved host and symbiont digestive enzymes from R. flavipes that include GHF7 exoglucanases, GHF1 beta glucosidases, phenol-oxidizing laccases, and others.
MAPK-directed activation of the whitefly transcription factor CREB leads to P450-mediated imidacloprid resistance
The trans-regulation of CYP6CM1, a cytochrome P450 that confers resistance to neonicotinoid insecticides in the whitefly Bemisia tabaci is resolved by the mitogen-activated protein kinase (MAPK)-directed activation of the transcription factor cAMP-response element binding protein (CREB).
