DNA modifications impact natural transformation of Acinetobacter baumannii

Melanie Blokesch, Nicolas Jean Philippe Guex, Christian Iseli, Alexandre Lemopoulos, Nina Vesel

Acinetobacter baumannii is a dangerous nosocomial pathogen, especially due to its ability to rapidly acquire new genetic traits, including antibiotic resistance genes (ARG). In A. baumannii, natural competence for transformation, one of the primary modes o ...

Identifying genetic and dietary modulators of metabolic disorders using systems genetics

Xiaoxu Li

Long-term consumption of lipid-rich foods can contribute to common metabolic diseases and systemic low-grade inflammation. However, dietary responses and the development of non-communicable diseases are shaped by genetic factors and gene-by-environment int ...

The SNP-Based Profiling of Montecristo Feral Goat Populations Reveals a History of Isolation, Bottlenecks, and the Effects of Management

Elia Vajana

The Montecristo wild goat is an endangered feral population that has been on the homonymous island in the Tuscan Archipelago since ancient times. The origins of Montecristo goats are still debated, with authors dating their introduction either back to Neol ...

Response of alpine stream biofilms to climate change induced stressors

Tom Ian Battin, Hannes Markus Peter, Grégoire Marie Octave Edouard Michoud, Nicola Deluigi, David Touchette, Martina Gonzalez Mateu, Paraskevi Pramateftaki

Alpine streams are expected to face an intensification of environmental stressors due to climate change. At the vanishing cryosphere interface, alpine streams are particularly susceptible to increasing temperatures and to changing hydrology. As biofilms ar ...

Response of alpine stream biofilms to climate change induced stressors

Tom Ian Battin, Hannes Markus Peter, Grégoire Marie Octave Edouard Michoud, Nicola Deluigi, David Touchette, Martina Gonzalez Mateu, Stylianos Fodelianakis, Paraskevi Pramateftaki

Alpine streams are expected to face an intensification of environmental stressors due to climate change. Being at the interface of the vanishing cryosphere, alpine streams are particularly susceptible to increasing temperatures and to changing hydrology. A ...

Genetic signatures of divergent selection in European beech (Fagus sylvatica L.) are associated with the variation in temperature and precipitation across its distribution range

Elia Vajana

High genetic variation and extensive gene flow may help forest trees with adapting to ongoing climate change, yet the genetic bases underlying their adaptive potential remain largely unknown. We investigated range-wide patterns of potentially adaptive gene ...

Barcoding analysis and taxonomic revision of Goliathus Lamarck, 1802 (Scarabaeidae, Cetoniinae)

Michele De Palma

We conducted barcoding analysis of valid taxa in the genus Goliathus Lamarck, 1802 and clarified their relationships. Specimens of Goliathus goliatus (Drury, 1770) sampled in tropical rainforests from Cameroon to Kenya display degrees of genetic and phenot ...

The population genetics of crypsis in vertebrates: recent insights from mice, hares, and lizards

Jeffrey David Jensen, Susanne Petra Pfeifer, Stefan Jean Laurent

By combining well-established population genetic theory with high-throughput sequencing data from natural populations, major strides have recently been made in understanding how, why, and when vertebrate populations evolve crypsis. Here, we focus on backgr ...

Biogeoinformatics for the management of Farm Animal Genetic Resources (FAnGR)

Solange Catherine Gaillard

In the context of both severe selection in farm animals and potential effects of climate change, it is crucial to implement a sustainable management of the breeding practice, supported by a judicious use of geographic information technologies. Based on thi ...

Neighbor predation linked to natural competence fosters the transfer of large genomic regions in Vibrio cholerae

Melanie Blokesch, Nicolas Jean Philippe Guex, Christian Iseli, Sandrine Stutzmann, Candice Stoudmann, Noémie Matthey

Natural competence for transformation is a primary mode of horizontal gene transfer. Competent bacteria are able to absorb free DNA from their surroundings and exchange this DNA against pieces of their own genome when sufficiently homologous. However, the ...
