The Unusual Neotenic System of the Asian Dry Wood Termite, Neotermes koshunensis (Isoptera: Kalotermitidae) [PDF]
Sociobiology, 2013 In most lower termites, colonies are headed by neotenic reproductives of both sexes after the primary reproductives (i.e., the queen and king) are lost.

Refinement of Methods for Sexing Instars and Caste Members in Neotermes koshunensis (Isoptera, Kalotermitidae) [PDF]
Sociobiology, 2014 Exact sexing of individuals is important to an understanding of termite societies. We found that the female-specific sexual character of the elongated seventh sternite, known in other termites, is useful for distinguishing the sex of individuals of the ...

Facultative parthenogenesis in the Ryukyu drywood termite Neotermes koshunensis. [PDF]
Sci Rep, 2016 AbstractParthenogenesis is a relatively rare reproductive mode in nature compared to sex. In social insects, the evolution of parthenogenesis has a notable impact on their life histories. Some termites with parthenogenetic ability produce numerous non-dispersing supplementary queens asexually, whereas other castes are produced via sexual reproduction ...

The complete mitochondrial genome of Neotermes koshunensis (Shiraki, 1909) (Blattodea: Termitoidae: Kalotermitidae) and its phylogenetic implications [PDF]
Mitochondrial DNA. Part B. Resources, 2019 In this article, we describe the complete mitochondrial genome of Neotermes koshunensis from the Pingtung County, Taiwan. This mitogenome is 15,589 bp long, containing 13 protein-coding genes, 22 tRNA genes, and 2 rDNA genes.

Culture-independent characterization of a gene responsible for nitrogen fixation in the symbiotic microbial community in the gut of the termite Neotermes koshunensis. [PDF]
Appl Environ Microbiol, 1999 ABSTRACT Expression of the nitrogen fixation gene, nifH , in the gut of the termite Neotermes koshunensis was characterized without cultivation. nifH cDNA was directly amplified from mRNA of the mixed microbial population in the gut by reverse transcription ...

Antennal cropping in the Asian dry-wood termite, Neotermes koshunensis [PDF]
Insectes Sociaux, 2014 Antennal cropping, a behavior inferred to exist because queens and kings have shorter antennae than fresh alates, is widespread in termites. However, the proximate and ultimate mechanisms underlying this phenomenon remain unclear. We studied the occurrence of antennal cropping in queens and kings of the dry-wood termite Neotermes koshunensis ...

Complex coevolutionary history of symbiotic Bacteroidales bacteria of various protists in the gut of termites. [PDF]
BMC Evol Biol, 2009 Background The microbial community in the gut of termites is responsible for the efficient decomposition of recalcitrant lignocellulose. Prominent features of this community are its complexity and the associations of prokaryotes with the cells of ...

A mechanism of glucose tolerance and stimulation of GH1 β-glucosidases. [PDF]
Sci Rep, 2015 β-Glucosidases are enzymes that hydrolyze β-glycosidic bonds to release non-reducing terminal glucosyl residues from glycosides and oligosaccharides, and thus have significant application potential in industries. However, most β-glucosidases are feedback

Functional characterization and target discovery of glycoside hydrolases from the digestome of the lower termite Coptotermes gestroi. [PDF]
Biotechnol Biofuels, 2011 Background Lignocellulosic materials have been moved towards the forefront of the biofuel industry as a sustainable resource. However, saccharification and the production of bioproducts derived from plant cell wall biomass are complex and ...

Spatial separation of the cyanogenic β-glucosidase ZfBGD2 and cyanogenic glucosides in the haemolymph of Zygaena larvae facilitates cyanide release. [PDF]
R Soc Open Sci, 2017 Low molecular weight compounds are typically used by insects and plants for defence against predators. They are often stored as inactive β-glucosides and kept separate from activating β-glucosidases.
