The RPG gene of Medicago truncatula controls Rhizobium-directed polar growth during infection

JF Arrighi, O Godfroy, F De Billy… - Proceedings of the …, 2008 - National Acad Sciences
Rhizobia can infect roots of host legume plants and induce new organs called nodules, in
which they fix atmospheric nitrogen. Infection generally starts with root hair curling, then …

OUROBOROS is a master regulator of the gametophyte to sporophyte life cycle transition in the brown alga Ectocarpus

SM Coelho, O Godfroy, A Arun… - Proceedings of the …, 2011 - National Acad Sciences
The brown alga Ectocarpus siliculosus has a haploid–diploid life cycle that involves an
alternation between two distinct generations, the sporophyte and the gametophyte. We describe …

Targeted CRISPR‐Cas9‐based gene knockouts in the model brown alga Ectocarpus

…, D Scornet, M Harada, C Caillard, O Godfroy… - New …, 2021 - Wiley Online Library
Brown algae are an important group of multicellular eukaryotes, phylogenetically distinct from
both the animal and land plant lineages. Ectocarpus has emerged as a model organism to …

Re‐annotation, improved large‐scale assembly and establishment of a catalogue of noncoding loci for the genome of the model brown alga Ectocarpus

…, V Wucher, G Andres, M Monsoor, O Godfroy… - New …, 2017 - Wiley Online Library
The genome of the filamentous brown alga Ectocarpus was the first to be completely sequenced
from within the brown algal group and has served as a key reference genome both for …

Evolution and regulation of complex life cycles: a brown algal perspective

JM Cock, O Godfroy, N Macaisne, AF Peters… - Current opinion in plant …, 2014 - Elsevier
… Author links open overlay panel J Mark Cock 1 2 , Olivier Godfroy 1 2 , Nicolas Macaisne 1 2

[HTML][HTML] instaGRAAL: chromosome-level quality scaffolding of genomes using a proximity ligation-based scaffolder

…, A Cormier, M Marbouty, K Avia, YL Mie, O Godfroy… - Genome Biology, 2020 - Springer
Hi-C exploits contact frequencies between pairs of loci to bridge and order contigs during
genome assembly, resulting in chromosome-level assemblies. Because few robust programs …

A rice calcium-and calmodulin-dependent protein kinase restores nodulation to a legume mutant

O Godfroy, F Debellé, T Timmers… - Molecular plant …, 2006 - Am Phytopath Society
The Medicago truncatula DMI3 gene encodes a calcium- and calmodulin-dependent protein
kinase (CCaMK) that is necessary for the establishment of both rhizobial and mycorrhizal …

Convergent recruitment of TALE homeodomain life cycle regulators to direct sporophyte development in land plants and brown algae

…, M Strittmatter, AP Lipinska, H Yao, O Godfroy… - Elife, 2019 - elifesciences.org
10.7554/eLife.43101.001 Three amino acid loop extension homeodomain transcription
factors (TALE HD TFs) act as life cycle regulators in green algae and land plants. In mosses …

[HTML][HTML] Selection drives convergent gene expression changes during transitions to co-sexuality in haploid sexual systems

GG Cossard, O Godfroy, Z Nehr, C Cruaud… - Nature Ecology & …, 2022 - nature.com
Co-sexuality has evolved repeatedly from unisexual (dioicous) ancestors across a wide
range of taxa. However, the molecular changes underpinning this important transition remain …

Chromatin landscape associated with sexual differentiation in a UV sex determination system

…, S Bourdareau, G Cossard, O Godfroy… - Nucleic acids …, 2022 - academic.oup.com
In many eukaryotes, such as dioicous mosses and many algae, sex is determined by UV sex
chromosomes and is expressed during the haploid phase of the life cycle. In these species, …
