Unravelling the evolution of wood-feeding in termites with 47 high-resolution genome assemblies

Cong Liu, Cédric Aumont, Alina A. Mikhailova, Tracy Lynn Audisio et autres

Termites are a lineage of social cockroaches abundant in tropical ecosystems where they are key decomposers of organic matter. Despite their ecological significance, only a handful of reference-quality termite genomes have been sequenced, which is insufficient to unravel the genetic mechanisms that …

Cryptotermes mobydicki (Isoptera, Kalotermitidae), an extraordinary new termite species from French Guiana

Rudolf H. Scheffrahn, Aleš Buček, David Sillam‐Dussès, Jan Šobotník

Cryptotermes mobydicki sp. nov. is described from the soldier caste. The soldier is unique among all Cryptotermes species worldwide for its very narrow, elongate head capsule terminating with an extended frontal process. The new species constitutes the sixteenth Cryptotermes species for South …

Balancing Barcoding and Genomics: gDNA Quality in Insect Vouchers after HotSHOT DNA extraction

Vivian Feng, Caroline Høegh-Guldberg, Aleš Buček, Rudolf Meier

Abstract DNA extraction with an alkaline buffer system called “HotSHOT” is widely used for barcoding because it is rapid, inexpensive, and voucher preserving, but it remains unclear whether sufficient genomic DNA (gDNA) remains in small vouchers for downstream use in genomics. We …

Horizontal gene transfers are widespread across termite genomes but do not confer metabolic innovations

Cong Liu, Simon Hellemans, Yukihiro Kinjo, Alina A. Mikhailova et autres

Horizontal gene transfer (HGT), the transmission of genetic material across species, is an important innovation source in prokaryotes. In contrast, its significance is unclear in many eukaryotes, including insects. Here, we used high-quality genomes of 45 termites and two cockroaches to investigate …

Unravelling termite evolution with 47 high-resolution genome assemblies

Cong Liu, Cédric Aumont, Alina A. Mikhailova, Tracy Lynn Audisio et autres

Abstract Termites are a lineage of social cockroaches abundant in tropical ecosystems where they are key decomposers of organic matter from wood to soil. Despite their ecological significance, only a handful of reference-quality termite genomes have been sequenced, which is insufficient to …

Phylogenomics reveals the timescale of diversification in Amblycera

Tomáš Najer, Jorge Doña, Aleš Buček, Andrew D. Sweet et autres

Abstract Recently, genomic approaches have helped to resolve phylogenetic questions in many groups of parasitic organisms, including lice (Phthiraptera). However, these approaches have still not been applied to one of the most diverse groups of lice, Amblycera. To fill this gap, we …

Termites and subsocial roaches inherited many bacterial-borne carbohydrate-active enzymes (CAZymes) from their common ancestor

Tereza Beránková, Jigyasa Arora, Johanna Romero Arias, Aleš Buček et autres

Termites digest wood using Carbohydrate-Active Enzymes (CAZymes) produced by gut bacteria with whom they have cospeciated at geological timescales. Whether CAZymes were encoded in the genomes of their ancestor’s gut bacteria and transmitted to modern termites or acquired more recently from bacteria …

Genomic data provide insights into the classification of extant termites

Simon Hellemans, Mauricio M. Rocha, Menglin Wang, Johanna Romero Arias et autres

The higher classification of termites requires substantial revision as the Neoisoptera, the most diverse termite lineage, comprise many paraphyletic and polyphyletic higher taxa. Here, we produce an updated termite classification using genomic-scale analyses. We reconstruct phylogenies under diverse substitution models with ultraconserved …

Mitochondrial genome fragmentation is correlated with increased rates of molecular evolution

Tomáš Najer, Jorge Doña, Aleš Buček, Andrew D. Sweet et autres

While mitochondrial genome content and organization is quite diverse across all Eukaryotes, most bilaterian animal mitochondrial genomes (mitogenomes) exhibit highly conserved gene content and organisation, with genes typically encoded on a single circular chromosome. However, many species of parasitic lice (Insecta: Phthiraptera) …

Extinct and extant termites reveal the fidelity of behavior fossilization in amber

Nobuaki Mizumoto, Simon Hellemans, Michael S. Engel, Thomas Bourguignon et autres

Fossils encompassing multiple individuals provide rare direct evidence of behavioral interactions among extinct organisms. However, the fossilization process can alter the spatial relationship between individuals and hinder behavioral reconstruction. Here, we report a Baltic amber inclusion preserving a female–male pair of the …
