Characterization of the complete mitochondrial genome of Cryptotermes domesticus (Blattodea: Kalotermitidae): Genome description and phylogenetic implications. [PDF]

Arch Insect Biochem Physiol, 2023
This study sequenced and analyzed the complete mitochondrial genome of Cryptotermes domesticus and reveal its mitogenomic characteristics. Phylogenetic analysis was performed using Bayesian inference and maximum likelihood methods based on 13 protein‐coding genes, and the monophyly of Kalotermitidae was supported.

Plastic brain structure changes associated with the division of labor and aging in termites. [PDF]

Dev Growth Differ, 2023
Termites restructure their nervous systems to perform necessary tasks as they undergo caste differentiation, and they also show flexible changes in brain morphology even after the final molt. Abstract Division of labor is a prominent feature of social insect societies, where different castes engage in different specialized tasks.

Mechanism of imidazole inhibition of a GH1 β-glucosidase. [PDF]

FEBS Open Bio, 2023
Imidazole is largely employed in recombinant protein purification, including of GH1 β‐glucosidases, but its effect on the enzyme activity is overlooked. Computational docking suggested that imidazole interacts within the active site of a GH1 β‐glucosidase.

Male-specific alleles in the Ryukyu drywood termite Neotermes sugioi. [PDF]

Ecol Evol, 2020
An incipient colony of Neotermes sugioi found from a twig. Our microsatellite analysis revealed male‐specific alleles at the microsatellite locus NK12‐1 in N. sugioi, which is a small but important step to elucidate the evolutionary process of the sex determination system in termites.

Characterization of new cristamonad species from kalotermitid termites including a novel genus, Runanympha [PDF]

, 2021
Cristamonadea is a large class of parabasalian protists that reside in the hindguts of wood-feeding insects, where they play an essential role in the digestion of lignocellulose. This group of symbionts boasts an impressive array of complex morphological

Characterization and phylogenomic analysis of Breznakiella homolactica gen. nov. sp. nov. indicate that termite gut treponemes evolved from non‐acetogenic spirochetes in cockroaches

Environmental Microbiology, Volume 23, Issue 8, Page 4228-4245, August 2021., 2021
Summary Spirochetes of the genus Treponema are surprisingly abundant in termite guts, where they play an important role in reductive acetogenesis. Although they occur in all termites investigated, their evolutionary origin is obscure. Here, we isolated the first representative of ‘termite gut treponemes’ from cockroaches, the closest relatives of ...

Male’s influence on the primary sex ratio bias in Ryukyu drywood termite [PDF]

, 2023
Selfish genetic elements (SGEs) increase their transmission efficiency relative to the rest of the individual genome, which is often deleterious to individual fitness.

Heterologous expression and enzymatic characterization of .BETA.-glucosidase from the drywood-eating termite, Neotermes koshunensis

Applied Entomology and Zoology, 2007
A β-glucosidase cDNA from the termite, Neotermes koshunensis, was successfully overexpressed in Escherichia coli, and the product was purified to homogeneity by affinity purification against His-tags. The molecular weight of the recombinant enzyme was 60 kDa. The expressed β-glucosidase preferentially hydrolyzed laminaribiose and cellobiose rather than
