Theoretical evaluation of 15N isotopic methods for measuring symbiotic nitrogen fixation in the fied
2008
International audience; Isotopic methods for the measurement of symbiotic N2 fixation by leguminous plants in the field rely on the use of differences in 15N enrichment between the N sources potentially available for leguminous crops, soil mineral N and atmospheric N2 . This methodology has been fully documented, especially concerning limitations due to non uniform and non constant distribution of 15N and to the use of a reference plant to measure it. Although all authors recognise the necessity of isotopic methods for giving yield independent and time-integrated estimates of symbiotic fixation, they also agree that these methods intrinsically remain imperfect. Our aim in this chapter is (i…

Les symbioses fixatrices d'azote
2012
Les plantes dites "fixatrices symbiotiques d'azote", comme toutes les plantes, ont besoin d'azote, mais ont la propriété remarquable de pouvoir puiser cet élément à partir de l'atmosphère, tandis que les autres plantes cultivées doivent recevoir des engrais azotés. En fait, ce n’est pas la plante elle-même qui est capable de fixer l'azote de l'air, mais des bactéries spécifiques avec lesquelles elles vivent en association au niveau d'organes particuliers : les nodosités. C'est le cas de deux principaux groupes de plantes : les légumineuses (ou fabacées) qui s'associent avec les Rhizobia et des plantes appartenant à huit familles d'angiospermes (dites actinorhiziennes) qui s'associent avec l…
How does pea (Pisum sativum) recover from water deficit?
2019
International audience; Pea (Pisum sativum), like other legumes, has the unique ability to fix atmospheric dinitrogen (N2) via symbiosis with soil bacteria known as rhizobia in root nodules. This particular feature makes the pea crop an essential component of sustainable cropping systems because of the reduction of nitrogen fertilizers it affords. However symbiotic nitrogen fixation (SNF) is very susceptible to abiotic stresses and particularly to water deficit, which is becoming an increasingly common threat in the current context of climate change. Water deficit impacts negatively SNF (Prudent et al., 2016), affecting both nodule number and growth (i.e. structural components of SNF) and t…
