Impact of complex spatial population structure on early and long-term adaptation in rugged fitness landscapes

1 code implementation25 Sep 2024 Richard Servajean, Arthur Alexandre, Anne-Florence Bitbol

Furthermore, we show that, in most landscapes, migration asymmetries associated with some suppression of natural selection allow the population to reach higher fitness peaks first.

DiffPaSS -- High-performance differentiable pairing of protein sequences using soft scores

no code implementations24 Sep 2024 Umberto Lupo, Damiano Sgarbossa, Martina Milighetti, Anne-Florence Bitbol

We introduce DiffPaSS, a differentiable framework for flexible, fast, and hyperparameter-free optimization for pairing interacting biological sequences, which can be applied to a wide variety of scores.

Spatial structure facilitates evolutionary rescue by drug resistance

1 code implementation11 Sep 2024 Cecilia Fruet, Ella Linxia Müller, Claude Loverdo, Anne-Florence Bitbol

Our main result that spatial structure facilitates evolutionary rescue by antibiotic resistance extends to more complex spatial structures, and to the case where there are resistant mutants in the inoculum.

We investigate the potential scale of this vulnerability by measuring the degree to which AI assistants can complete assessment questions in standard university-level STEM courses.

Bridging Wright-Fisher and Moran models

no code implementations17 Jul 2024 Arthur Alexandre, Alia Abbara, Cecilia Fruet, Claude Loverdo, Anne-Florence Bitbol

The Wright-Fisher model and the Moran model are both widely used in population genetics.

Impact of phylogeny on the inference of functional sectors from protein sequence data

no code implementations8 May 2024 Nicola Dietler, Alia Abbara, Subham Choudhury, Anne-Florence Bitbol

However, a challenge for all methods aiming to identify sectors from multiple sequence alignments is that correlations in amino-acid usage can also arise from the mere fact that homologous sequences share common ancestry, i. e. from phylogeny.

Mutant fate in spatially structured populations on graphs: connecting models to experiments

1 code implementation6 Feb 2024 Alia Abbara, Lisa Pagani, Celia García-Pareja, Anne-Florence Bitbol

Evolutionary graph theory predicts that some spatial structures modelled by placing individuals on the nodes of a graph affect the probability that a mutant will fix.

Evolution of cooperation in deme-structured populations on graphs

no code implementations18 Sep 2023 Alix Moawad, Alia Abbara, Anne-Florence Bitbol

Models of spatially structured populations with one individual per node of a graph have shown that cooperation, modeled via the prisoner's dilemma, can be favored by natural selection.

Pairing interacting protein sequences using masked language modeling

1 code implementation14 Aug 2023 Umberto Lupo, Damiano Sgarbossa, Anne-Florence Bitbol

We introduce a method called DiffPALM that solves it by exploiting the ability of MSA Transformer to fill in masked amino acids in multiple sequence alignments using the surrounding context.

Impact of phylogeny on structural contact inference from protein sequence data

no code implementations26 Sep 2022 Nicola Dietler, Umberto Lupo, Anne-Florence Bitbol

Local and global inference methods have been developed to infer structural contacts from multiple sequence alignments of homologous proteins.

Combining phylogeny and coevolution improves the inference of interaction partners among paralogous proteins

no code implementations24 Aug 2022 Carlos A. Gandarilla-Perez, Sergio Pinilla, Anne-Florence Bitbol, Martin Weigt

We show that these two signals can be combined to improve the performance of the inference of interaction partners among paralogs.

Impact of population size on early adaptation in rugged fitness landscapes

1 code implementation11 Aug 2022 Richard Servajean, Anne-Florence Bitbol

Due to stochastic fluctuations arising from finite population size, known as genetic drift, the ability of a population to explore a rugged fitness landscape depends on its size.

Protein language models trained on multiple sequence alignments learn phylogenetic relationships

1 code implementation29 Mar 2022 Umberto Lupo, Damiano Sgarbossa, Anne-Florence Bitbol

Simple combinations of MSA Transformer's row attentions have led to state-of-the-art unsupervised structural contact prediction.

Correlations from structure and phylogeny combine constructively in the inference of protein partners from sequences

1 code implementation22 Nov 2021 Andonis Gerardos, Nicola Dietler, Anne-Florence Bitbol

We show that correlations from these two sources combine constructively to increase the performance of partner inference by DCA or MI.

Toward a universal model for spatially structured populations

no code implementations12 Dec 2020 Loïc Marrec, Irene Lamberti, Anne-Florence Bitbol

We demonstrate that by tuning migration asymmetry, the star graph transitions from amplifying to suppressing natural selection.
