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intraradices genes which have been previously identified as markers of successful symbiosis development (Seddas et al., unpublished results) were chosen.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…

Changes in polypeptide profiles of two pea genotypes inoculated with the arbuscular mycorrhizal fungus Glomus mosseae

1994

The symbiotic interaction between pea roots ('Pisum sativum' L.) and the endomycorrhizal fungus 'Glomus mosseae' should lead to specific gene expression of both symbionts. In order to detect symbiosis-related proteins (endomycorrhizins), we used two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) after phenolic extraction of total soluble proteins. Furthermore, to better characterize the molecular changes after fungal infection, two pea genotypes available in our laboratory were used: cv. Frisson (myc⁺) and an isogenic mycorrhiza-resistant mutant (myc⁻). The latter prevents intraradical fungal development. Several differences were observed in polypeptide patterns of silver-stained …

Comment la plante récupère-t-elle après un stress hydrique ? Une étude écophysiologique et moléculaire chez la légumineuse à graines Pisum sativum

2017

EABAPGEAPSI DOCT INRA; Le pois (Pisum sativum) possède la capacité de fixer l’azote atmosphérique via une symbiose avec des bactéries du sol, permettant ainsi de s’affranchir d’engrais azotés. Cependant, ce processus est très sensible au stress hydrique, et reste affecté même lorsque les conditions hydriques redeviennent optimales. Or, la capacité d’une plante à récupérer après un stress hydrique peut être déterminante pour l’élaboration de son rendement. Pourtant, les mécanismes enclenchés lors de la phase de récupération restent peu connus. Le but de cette thèse est d’évaluer la capacité de la plante à récupérer après un stress hydrique et d’identifier les processus écophysiologiques et m…

Influence of pea genotype on root associated fluorescent pseudomonads, impact on plant iron nutrition

2019

International audience; Pea has a high potential in agroecology because of its ability to fix atmospheric nitrogen and for Humannutrition due to the high amino-acids content of its seeds. However, pea can suffer from a susceptibility toiron deficiency in calcareous soils as expressed by chlorosis symptoms. Previous studies have shown thatsiderophores of model strains of fluorescent pseudomonads (fp), pyoverdines, promote iron nutrition ofarabidopsis and tobacco. We hypothesized that susceptibility to iron deficiency of pea is at least partly dueto its ability to select fluorescent pseudomonad that promote differentially plant nutrition thanks to theirsiderophores.To identify siderophores po…

Déterminisme génétique de la composition protéique des graines de légumineuses et de sa plasticité vis-à-vis de l’environnement

2018

Les légumineuses sont capables de produire des graines riches en protéines sans apport d’engrais azoté grâce à la symbiose racinaire avec des bactéries du genre rhizobium. Riches en lysine, ces protéines sont utilisées pour l’alimentation des animaux d’élevage et en nutrition humaine. Afin de promouvoir la culture des légumineuses, il est nécessaire d’optimiser et de stabiliser la qualité de cette fraction protéique. L’objectif de ma thèse est de mettre en évidence les déterminismes génétiques sous-jacents à la teneur et à la composition protéique des graines de légumineuses ainsi qu’à la plasticité de ces composantes vis-à-vis de l’environnement. Afin de répondre à cet objectif, l’approche…

Recherche de critères phénotypiques et moléculaires discriminants des différentes espèces et sous-espèces du genre Pisum

2014

The Pisum genus presents a large genetic diversity, that makers difficult its taxonomic classification. The Center for Grain Legumes Genetic Resources holds 1800 pea accessions. Some of them are lacking passport data. Previous genotyping studies have identified SNP markers specific to wild Pisum pools. The main aim of my work was to conceive simple criteria in order to classify the unknown genotypes. Towards this goal, plants have been observed at the phenotypic level and their DNA were extracted for their characterisation using discriminating SNP markers. Furthermore, candidate genes of domestication were sequenced. Our results clearly showed distinctive traits between the P. sativum and P…
