Localisation et visualisation de transcrits fongiques in situ: Une méthode originale qui combine biologie moléculaire et microscopie confocale
2011
National audience; Les Gloméromycètes, formant la symbiose mycorhizienne à arbuscules, sont des champignons biotrophes obligatoires qui sont intimement associés aux tissus végétaux qu’ils colonisent. Les techniques utilisées pour suivre l’expression des gènes fongiques dans les racines mycorhizées ne permettent pas de définir le profil spatio-temporel de leur activité. Afin de tracer l’activité transcriptionnelle fongique dans les racines mycorhizées, une méthode innovante, basée sur la RT-PCR in situ, a donc été développée. Cette technique permet de localiser, en microscopie optique confocale à balayage laser, des transcrits fongiques, à l’aide d’amorces spécifiques marquées par un fluoroc…

Genes encoding transcription factors in Glomus intraradices and their expression at the appressoria stage of arbuscular mycorrhiza interactions
2007
International audience; Molecular pathways governing the life cycle of arbuscular mycorrhizal (AM) fungi and their symbiotic interactions with root tissues are not yet fully understood. Most studies fo fungal responses to host plants have targeted developmental stages before root contact (germinating spores), or after root colonization (intraradical mycelium). We are focusing on the early cell events of appressoria contact with the root surface which are essential to the successful outcome of the AM symbiosis. Recent monitoring of Glomus intraradices gene expression at this stage has revealed differential fungal responses to roots of host and non-host (Myc- mutants) M. truncatula (Seddas et…
Effect of the pea (Pisum sativum L.) gene PsSym36 on Glomus intraradices gene expression
2007
International audience; The Pisum sativum L. mutant RisNod24 (Pssym36) is defective for arbuscular mycorrhiza formation in late stages of AM. Recent studies identified some plant genes up- and down- regulated at stage of arbuscular development using pea mutant RisNod24, but nothing is still known about fungal gene inactivation. To investigate effect of PsSym36 pea gene on fungal gene expression, Glomus intraradices genes which have been previously identified as markers of successful symbiosis development (Seddas et al., unpublished results) were chosen. List of AM genes used in this study: signalling, transcription, protein turn-over (RHO/GDP dissociation inhibitor, Peptidylprolyl isomerase…
