Journal ArticleDOI
Plant peptides govern terminal differentiation of bacteria in symbiosis.
Willem Van de Velde,Grigor Zehirov,Ágnes Szatmári,Ágnes Szatmári,Monika Debreczeny,Hironobu Ishihara,Zoltan Kevei,Attila Farkas,Kata Mikulass,Andrea M. Nagy,Hilda Tiricz,Béatrice Satiat-Jeunemaitre,Benoit Alunni,Mickael Bourge,Ken-ichi Kucho,Mikiko Abe,Attila Kereszt,Gergely Maróti,Toshiki Uchiumi,Eva Kondorosi,Peter Mergaert +20 more
TL;DR: It is demonstrated that nodule-specific cysteine-rich NCR peptides are targeted to the bacteria and enter the bacterial membrane and cytosol and reveal a previously unknown innovation of the host plant that adopts effectors of the innate immune system for symbiosis to manipulate the cell fate of endosymbiotic bacteria.
Journal ArticleDOI
Eukaryotic control on bacterial cell cycle and differentiation in the Rhizobium-legume symbiosis
Peter Mergaert,Toshiki Uchiumi,Toshiki Uchiumi,Benoit Alunni,Gwénaëlle Evanno,Angélique Chéron,Olivier Catrice,Anne Elisabeth Mausset,Frédérique Barloy-Hubler,Francis Galibert,Adam Kondorosi,Eva Kondorosi +11 more
TL;DR: It is demonstrated that differentiation of bacteroids in indeterminate nodules of Medicago and related legumes from the galegoid clade shows remarkable similarity to host cell differentiation, which reveals a positive correlation in prokaryotes between DNA content and cell size, similar to that in eukaryotes.
Journal ArticleDOI
Differentiation of Symbiotic Cells and Endosymbionts in Medicago truncatula Nodulation Are Coupled to Two Transcriptome-Switches
Nicolas Maunoury,Miguel Redondo-Nieto,Marie Bourcy,Willem Van de Velde,Benoit Alunni,Philippe Laporte,Patricia Durand,Nicolas Agier,Laetitia Marisa,Daniele Vaubert,Hervé Delacroix,Hervé Delacroix,Gérard Duc,Pascal Ratet,Lawrence P. Aggerbeck,Eva Kondorosi,Eva Kondorosi,Peter Mergaert +17 more
TL;DR: A correlation exists between the differentiation of symbiotic nodule cells and the first wave of nodule specific gene activation and between differentiation of rhizobia to bacteroids and the second transcriptome wave in nodules, which may constitute signals for the execution of these transcriptome-switches.
Journal ArticleDOI
Genomic organization and evolutionary insights on GRP and NCR genes, two large nodule-specific gene families in Medicago truncatula.
Benoit Alunni,Zoltan Kevei,Miguel Redondo-Nieto,Miguel Redondo-Nieto,Adam Kondorosi,Peter Mergaert,Eva Kondorosi +6 more
TL;DR: Microsyntenic evidences between M. truncatula and L. japonicus validated the hypothesis that these genes are specific for the inverted repeat-lacking clade of hologalegoid legumes, which allowed dating the appearance of these two gene families during the evolution of legume plants.
Journal ArticleDOI
Comparative Transcriptomic Analysis of Salt Adaptation in Roots of Contrasting Medicago truncatula Genotypes

TL;DR: It is proposed that an increase in this bHLH TF expression may be linked to the adaptation of M. truncatula to saline soil environments, and improved significantly root growth under salt stress.
