Journal ArticleDOI
Characterization of root colonization profiles by a microcosm community of arbuscular mycorrhizal fungi using 25S rDNA‐targeted nested PCR
TL;DR: Root colonization by G. mosseae and G. intraradices was similar from individual and mixed inoculum, whilst the frequency of S. castanea and Gig.
Journal ArticleDOI
Cell defense responses associated with localized and systemic resistance to Phytophthora parasitica induced in tomato by an arbuscular mycorrhizal fungus
Christelle Cordier,María J. Pozo,José Miguel Barea,Silvio Gianinazzi,Vivienne Gianinazzi-Pearson +4 more
TL;DR: The arbuscular mycorrhizal fungus Glomus mosseae is able to confer bioprotection against Phytophthora parasitica in tomato roots and exhibits a localized resistance response with the formation of cell wall appositions reinforced by callose adjacent to intercellular hyphae.
Journal ArticleDOI
First report of non-mycorrhizal plant mutants (Myc−) obtained in pea (Pisum sativum L.) and fababean (Vicia faba L.)
TL;DR: Preliminary analysis of the genetic behaviour of the myc− mutants in diallel crosses has shown that at least three genes are involved in VA mycorrhiza infection.
Journal ArticleDOI
The transcriptome of the arbuscular mycorrhizal fungus Glomus intraradices (DAOM 197198) reveals functional tradeoffs in an obligate symbiont

TL;DR: The first genome-wide analysis of the transcriptome from Glomus intraradices is reported, suggesting that the lack of a known sexual cycle in G. intrarodices is not a result of major deletions of genes essential for sexual reproduction and meiosis.
Journal ArticleDOI
Medicago truncatula ENOD11: a novel RPRP-encoding early nodulin gene expressed during mycorrhization in arbuscule-containing cells.
Etienne-Pascal Journet,Naima El-Gachtouli,Vanessa Vernoud,Françoise de Billy,Magalie Pichon,Annie Dedieu,Christine Arnould,Dominique Morandi,David G. Barker,Vivienne Gianinazzi-Pearson +9 more
TL;DR: A novel RPRP-encoding gene, MtENOD11, is transcribed during preinfection and infection stages of nodulation in root and nodule tissues and it is demonstrated that this gene is also expressed during root colonization by endomycorrhizal fungi in inner cortical cells containing recently formed arbuscules.
