Journal ArticleDOI
Refined analysis of early symbiotic steps of the Rhizobium-Medicago interaction in relationship with microtubular cytoskeleton rearrangements.
TL;DR: A model suggests the existence of two opposite gradients of cell differentiation controlling respectively the formation of division centers in the inner cortex and plant preparation for infection, and in alfalfa PIT differentiation requires complementary signaling additional to Nod factors.
Journal ArticleDOI
Saprophytic intracellular rhizobia in alfalfa nodules.
Antonius C.J. Timmers,E. Soupène,Marie-Christine Auriac,F. de Billy,Jacques Vasse,P. Boistard,G. Truchet +6 more
TL;DR: The results support the conclusion that zone V is an ecological niche where intracellular rhizobia take advantage of the interaction for their exclusive benefit and live as parallel saprophytic partners.
Journal ArticleDOI
Medicago truncatula ERN Transcription Factors: Regulatory Interplay with NSP1/NSP2 GRAS Factors and Expression Dynamics throughout Rhizobial Infection
Marion R. Cerri,Lisa Frances,Tom Laloum,Marie-Christine Auriac,Andreas Niebel,Giles E. D. Oldroyd,David G. Barker,Joëlle Fournier,Fernanda de Carvalho-Niebel +8 more
TL;DR: By cross complementation, it is shown that ERN2, when expressed under the control of the ERN1 promoter, can restore both NF-elicited ENOD11 expression and nodule formation in an ern1 mutant background, and that functional diversification of these closely related TFs relies primarily on changes in tissue-specific expression patterns.
Journal ArticleDOI
Reprogramming of DNA methylation is critical for nodule development in Medicago truncatula.
Carine Satgé,Sandra Moreau,Erika Sallet,Gaëlle Lefort,Marie-Christine Auriac,Céline Remblière,Ludovic Cottret,Karine Gallardo,Céline Noirot,Marie-Françoise Jardinaud,Pascal Gamas +10 more
TL;DR: It is shown that MtDME is essential for nodule development and regulates the expression of 1,425 genes, some of which are critical for plant and bacterial cell differentiation, including nodule-specific cysteine-rich peptide genes.
Journal Article
Nod factor internalization and microtubular cytoskeleton changes occur concomitantly during nodule differentiation in alfalfa
TL;DR: In situ immunolocalisation of tubulin reveals that important cytoskeletal changes, implying a transient disorganization followed by a newly patterned reorganization, occur in indeterminate and determinate nodules.
