Horizontal transfers between fungal Fusarium species contributed to successive outbreaks of coffee wilt disease

L. D. Peck, T. Llewellyn, B. Bennetot, S. O'Donnell, R. W. Nowell, M. J. Ryan, J. Flood, R. C. Rodriguez de la Vega, J. Ropars, T. Giraud, P. D. Spanu, T. G. Barraclough

This study identifies horizontal gene transfers from Fusarium oxysporum to Fusarium xylarioides as a mechanism driving the repeated outbreaks of coffee wilt disease.

Public goods exploitation is reduced in species-rich microbial communities

S. O'Brien, C. Culbert, T. G. Barraclough

The paper shows that in diverse microbial communities, siderophore exploitation by non-producers is reduced due to the presence of key species that inhibit non-producer growth.

Bdelloid rotifers use hundreds of horizontally acquired genes against fungal pathogens

R. W. Nowell, T. G. Barraclough, C. G. Wilson

The paper shows that horizontally acquired genes in bdelloid rotifers are more likely to be upregulated against fungal pathogens than against desiccation stress.

CRISPRs are associated with bacterial expansion in the human gut during the first year of life

J. Wu, T. G. Barraclough

This study identifies and analyzes CRISPRs in infant gut microbiomes, finding they are associated with bacterial expansion and influenced by gender.

Higher temperatures worsen the effects of mutations on protein stability

D. - G. Kontopoulos, I. Patmanidis, T. G. Barraclough, S. Pawar

This study shows that higher temperatures amplify the destabilizing effects of mutations on protein stability in prokaryotes, leading to decreased mutation rates with increasing temperature.

Evolutionary dynamics of transposable elements in bdelloid rotifers

R. W. Nowell, C. G. Wilson, P. Almeida, P. H. Schiffer, D. Fontaneto, L. Becks, F. Rodriguez, I. R. Arkhipova, T. G. Barraclough

This study analyzes TE dynamics in bdelloid rotifers, finding active TEs at frequencies similar to sexual species and expanded RNAi-related genes.

Adaptive evolution shapes the present-day distribution of the thermal sensitivity of population growth rate

D. - G. Kontopoulos, T. P. Smith, T. G. Barraclough, S. Pawar

The paper investigates how adaptive evolution shapes the thermal sensitivity of population growth rate across microbial and plant species, finding that thermal sensitivity evolves rapidly and shows convergence across clades.

Introgression across evolutionary scales suggests reticulation contributes to Amazonian tree diversity

R. J. Schley, T. Pennington, O. A. Perez-Escobar, A. J. Helmstetter, M. de la Estrella, I. Larridon, I. A. B. Sabino Kikuchi, T. G. Barraclough, F. Forest, B. B. Klitgaard

This study shows hybridization is common in Amazonian trees, with evidence of introgression across multiple lineages and time scales, challenging the view that hybridization is rare in the region.

Phytoplankton thermal responses adapt in the absence of hard thermodynamic constraints

D. - G. Kontopoulos, E. van Sebille, M. Lange, G. Yvon-Durocher, T. G. Barraclough, S. Pawar

This study analyzes phytoplankton thermal performance curves to assess the role of thermodynamic constraints in their evolution, finding weak constraints and significant phylogenetic adaptation.

Comparative genomics of bdelloid rotifers: evaluating the effects of asexuality and desiccation tolerance on genome evolution

R. W. Nowell, P. Almeida, C. G. Wilson, T. P. Smith, D. Fontaneto, A. Crisp, G. Micklem, A. Tunnacliffe, C. Boschetti, T. G. Barraclough

This study compares genome evolution in bdelloid rotifers to assess the impact of asexuality and desiccation tolerance, finding that desiccation is not the primary driver of genomic features previously attributed to asexuality.

Evidence for "inter- and intraspecific horizontal genetic transfers" between anciently asexual bdelloid rotifers is explained by cross-contamination

C. G. Wilson, R. W. Nowell, T. G. Barraclough

The paper shows that claims of horizontal genetic transfer in bdelloid rotifers are due to cross-contamination rather than actual genetic exchange.
