Plant genetic effects on microbial hubs impact fitness across field trials
Benjamin Brachi,Daniele L. Filiault,H. Whitehurst,Darme P,Le Gars P,Le Mentec M,Timothy Morton,Envel Kerdaffrec,Fernando A. Rabanal,Alison E. Anastasio,Mathew S. Box,Susan Duncan,Huang F,Huang F,R. Leff,Polina Yu. Novikova,Matthew Perisin,Takashi Tsuchimatsu,Woolley R,Caroline Dean,Magnus Nordborg,Svante Holm,Joy Bergelson +22 more
TL;DR: In this paper, the authors characterized the leaf microbiota of 200 A. thaliana genotypes in eight field experiments and detected consistent host effects on specific, broadly distributed microbial OTUs.

Genetic variants affecting plant size and chemical defenses jointly shape herbivory in Arabidopsis
Andrew D. Gloss,Benjamin Brachi,Mitchell J. Feldmann,Simon C. Groen,Claudia Bartoli,Jérôme Gouzy,LaPlante E,Christopher Meyer,Pyon H,Rogan S,Fabrice Roux,Joy Bergelson,Whiteman N +12 more
TL;DR: The authors applied genome-wide association (GWA) mapping to uncover genetic polymorphisms mediating damage from foraging insects (two populations of Scaptomyza flava) across a mixture of Arabidopsis thaliana genotypes in experimental enclosures.

The rate and effect of de novo mutations in natural populations of Arabidopsis thaliana
Moises Exposito-Alonso,Claude Becker,Verena J. Schuenemann,Ella Reitter,Claudia Setzer,Radka Slovak,Benjamin Brachi,Joerg Hagmann,Dominik G. Grimm,Jia-Hui Chen,Wolfgang Busch,Joy Bergelson,Rob W. Ness,Johannes Krause,Hernán A. Burbano,Detlef Weigel +15 more
TL;DR: Comparison of substitution rates at different sites throughout the genome reveals that genetic drift predominates, but that purifying selection in this rapidly expanding population is nevertheless evident even over short historical time scales, and identifies new mutations affecting root development, a trait important for adaptation in the wild.

The rate and effect of de novo mutations in a colonizing lineage of Arabidopsis thaliana
Moises Exposito-Alonso,Claude Becker,Verena J. Schuenemann,Ella Reiter,Claudia Setzer,Radka Slovak,Benjamin Brachi,Joerg Hagmann,Dominik G. Grimm,Jia-Hui Chen,Wolfgang Busch,Joy Bergelson,Rob W. Ness,Johannes Krause,Hernán A. Burbano,Detlef Weigel +15 more
TL;DR: In this article, the last common ancestor of the HPG1 lineage lived in the early 17th century, most likely the time when the Arabidopsis thaliana began to colonize N. America.
Journal ArticleDOI
Gene expression and genetic divergence in oak species highlight adaptive genes to soil water constraints.
Grégoire Le Provost,Benjamin Brachi,Isabelle Lesur,Céline Lalanne,Karine Labadie,Jean-Marc Aury,Corinne Da Silva,Dragos Postolache,Thibault Leroy,Christophe Plomion +9 more
TL;DR: This experimental design exposed oak seedlings to waterlogging and drought, conditions typically encountered by the two species in their respective habitats, and identified genes with functions consistent with a role in intrinsic reproductive barriers that revealed adaptive molecular strategies involving adventitious and lateral root formation.
