Toll-Riera M, Olombrada M, Castro-Giner F, Wagner A
Sci Adv
. 2022 Jul;
8(28):eabk3511.
PMID: 35857489
Climate change is gradual, but it can also cause brief extreme heat waves that can exceed the upper thermal limit of any one organism. To study the evolutionary potential of...

Humphrey S, San Millan A, Toll-Riera M, Connolly J, Flor-Duro A, Chen J, et al.
Nat Commun
. 2021 Oct;
12(1):5845.
PMID: 34615859
Conjugation has classically been considered the main mechanism driving plasmid transfer in nature. Yet bacteria frequently carry so-called non-transmissible plasmids, raising questions about how these plasmids spread. Interestingly, the size...

Rodriguez-Beltran J, Sorum V, Toll-Riera M, de la Vega C, Pena-Miller R, San Millan A
Proc Natl Acad Sci U S A
. 2020 Jun;
117(27):15755-15762.
PMID: 32571917
Mobile genetic elements (MGEs), such as plasmids, promote bacterial evolution through horizontal gene transfer (HGT). However, the rules governing the repertoire of traits encoded on MGEs remain unclear. In this...

Qi W, Colarusso A, Olombrada M, Parrilli E, Patrignani A, Tutino M, et al.
Sci Rep
. 2019 Nov;
9(1):16444.
PMID: 31712730
Pseudoalteromonas haloplanktis TAC125 is among the most commonly studied bacteria adapted to cold environments. Aside from its ecological relevance, P. haloplanktis has a potential use for biotechnological applications. Due to...

San Millan A, Toll-Riera M, Qi Q, Betts A, Hopkinson R, McCullagh J, et al.
ISME J
. 2018 Aug;
12(12):3014-3024.
PMID: 30097663
Horizontal gene transfer (HGT) mediated by the spread of plasmids fuels evolution in prokaryotes. Although plasmids provide bacteria with new adaptive genes, they also produce physiological alterations that often translate...

Nat Commun
. 2017 May;
8:15410.
PMID: 28524864
Phenotypic mutations are amino acid changes caused by mistranslation. How phenotypic mutations affect the adaptive evolution of new protein functions is unknown. Here we evolve the antibiotic resistance protein TEM-1...

Gifford D, Toll-Riera M, MacLean R
Evolution
. 2016 May;
70(7):1659-66.
PMID: 27230588
The idea that interactions between mutations influence adaptation by driving populations to low and high fitness peaks on adaptive landscapes is deeply ingrained in evolutionary theory. Here, we investigate the...

Toll-Riera M, San Millan A, Wagner A, MacLean R
PLoS Genet
. 2016 May;
12(5):e1006005.
PMID: 27149698
Novel traits play a key role in evolution, but their origins remain poorly understood. Here we address this problem by using experimental evolution to study bacterial innovation in real time....

Qi Q, Toll-Riera M, Heilbron K, Preston G, MacLean R
Proc Biol Sci
. 2016 Jan;
283(1822).
PMID: 26763710
Antibiotic resistance carries a fitness cost that must be overcome in order for resistance to persist over the long term. Compensatory mutations that recover the functional defects associated with resistance...

PMID: 26209313
Background: Carbapenemases are a major concern for the treatment of infectious diseases caused by Gram-negative bacteria. Although plasmids are responsible for the spread of resistance genes among these pathogens, there...
