Effect of the pea (Pisum sativum L.) gene PsSym36 on Glomus intraradices gene expression
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intraradices genes which have been previously identified as markers of successful symbiosis development (Seddas et al., unpublished results) were chosen.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…

Pathogenesis-related proteins in roots: a role in plant resistance or an epiphenomenon?
International audience; Although Pathogenesis-Related (PR) proteins have been identified in numerous monocotyledons and dicotyledons across different genera and in relation to very different physiological situations, relatively few studies have been conducted on roots which are the site of multimicrobial interactions. PR proteins are considered to be inducible proteins elicited by many environmental and developmental stimuli, but an increasing body of data points to their occurrence as constitutive components in different plant organs (Edreva 2005), including roots. This is the case, for example, of a Nicotiana glutinosa x Nicotiana debney hybrid which over-expresses PR protein genes and sh…
