Journal ArticleDOI
Differential Regulation of Root Arginine Catabolism and Polyamine Metabolism in Clubroot-Susceptible and Partially Resistant Arabidopsis Genotypes
Mélanie Jubault,Céline Hamon,Antoine Gravot,Christine Lariagon,Régine Delourme,Alain Bouchereau,Maria J. Manzanares-Dauleux +6 more
TL;DR: Results suggest that the symptom severity was strongly associated to the differential regulation of root polyamine metabolism and Arg catabolism in host responses to the pathogen infection and in partial clubroot resistance mechanisms.
Journal ArticleDOI
Both the Jasmonic Acid and the Salicylic Acid Pathways Contribute to Resistance to the Biotrophic Clubroot Agent Plasmodiophora brassicae in Arabidopsis
Séverine Lemarié,Alexandre Robert-Seilaniantz,Christine Lariagon,Jocelyne Lemoine,Nathalie Marnet,Mélanie Jubault,Maria J. Manzanares-Dauleux,Antoine Gravot +7 more
TL;DR: The data support the idea that, depending on the Arabidopsis accession, both SA and JA signaling can play a role in partial inhibition of clubroot development in compatible interactions with P. brassicae.
Journal ArticleDOI
Partial resistance to clubroot in Arabidopsis is based on changes in the host primary metabolism and targeted cell division and expansion capacity
Mélanie Jubault,Christine Lariagon,Ludivine Taconnat,Jean-Pierre Renou,Antoine Gravot,Antoine Gravot,Régine Delourme,Maria J. Manzanares-Dauleux,Maria J. Manzanares-Dauleux,Maria J. Manzanares-Dauleux +9 more
TL;DR: It was observed, at the transcriptomic level, that metabolic diversion by the pathogen was reduced or delayed, classical plant defense responses were induced earlier and/or more strongly, and cell enlargement and proliferation were actively inhibited in the partial quantitative resistance response compared to the susceptible one.
Journal ArticleDOI
Arginase Induction Represses Gall Development During Clubroot Infection In Arabidopsis
Antoine Gravot,Antoine Gravot,Carole Deleu,Carole Deleu,G. Wagner,G. Wagner,Christine Lariagon,Raphaël Lugan,Christopher D. Todd,David Wendehenne,David Wendehenne,Régine Delourme,Alain Bouchereau,Alain Bouchereau,Maria J. Manzanares-Dauleux,Maria J. Manzanares-Dauleux +15 more
TL;DR: It is reported here that the mutation of the arginase-encoding gene ARGAH2 abrogates clubroot-induced arginases activity and results in enhanced gall size in infected roots, suggesting that argin enzyme plays a defensive role.
Journal ArticleDOI
Hypoxia response in Arabidopsis roots infected by Plasmodiophora brassicae supports the development of clubroot
Antoine Gravot,Gautier Richard,Tanguy Lime,Séverine Lemarié,Mélanie Jubault,Christine Lariagon,Jocelyne Lemoine,Jorge Vicente,Alexandre Robert-Seilaniantz,Michael J. Holdsworth,Maria J. Manzanares-Dauleux +10 more
TL;DR: The data demonstrate that the induction of PDC1 and PDC2 during the secondary infection of roots by P. brassicae contributes positively to clubroot development, and that this is controlled by oxygen-sensing through ERFVIIs.
