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.

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.

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.

Supergene evolution triggered by the introgression of a chromosomal inversion

P. Jay, A. Whibley, L. Frezal, A. de Cara, R. W. Nowell, J. Mallet, K. K. Dasmahapatra, M. Joron

The paper shows that supergene alleles in Heliconius numata butterflies arise from introgression of a chromosomal inversion, leading to balanced polymorphism and mimicry polymorphism.

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.
