Typologie et logique socio-économique des systèmes de culture associant céréales et légumineuses dans les agro-écosystèm...
Dans la zone soudano-sahélienne du Burkina Faso, les associations mixtes céréales-légumineuses dominent les surfaces cultivées annuellement. Cependant, les rendements sont faibles et ne couvrent souvent pas les besoins alimentaires des exploitations qui les pratiquent. Afin d'améliorer la productivité de ces associations, il est nécessaire de compr...
Characterization of root-nodule bacteria isolated from Hedysarum spinosissimum L, growing in mining sites of Northeaster...
Assessing soil water trajectories and WUE: a multi-year modeling approach to design resilient cereal-legume rotations in...
Cropping system simulation can address the complex and interactive nature of resilience and allows for biological (crop growth and development), physical (soil-water dynamics), chemical (soil carbon and N turnover), and management related (e.g. crop choice, applications of nitrogen fertilizer, timing of sowing) aspects of resilience to be quantifie...
Rhizobium-legume symbiosis in the absence of Nod factors : two possible scenarios with or without the T3SS
...
The occurrence of alternative Nod factor (NF)-independent symbiosis between legumes and rhizobia was first demonstrated in some Aeschynomene species that are nodulated by photosynthetic bradyrhizobia lacking the canonical nodABC genes. In this study, we revealed that a large diversity of non-photosynthetic bradyrhizobia, including B. elkanii, was a...

Transitions agraires au sud de Madagascar : résilience et viabilité, deux facettes de la conservation : actes du séminai...
Suite à la création du parc national de la forêt de Mikea et au déclin des filières du coton et du maïs, dans le sud-ouest de Madagascar, les exploitations agricoles s'adaptent en diversifiant leurs activités. C'est l'hypothèse que nous testons dans la Commune d'Analamisampy, District de Tuléar. Deux typologies d'exploitations dans la même commune ...
CadA of Mesorhizobium metallidurans isolated from a zinc-rich mining soil is a P(IB-2)-type ATPase involved in cadmium a...
Mesorhizobium metallidurans STM 2683(T) is a nitrogen-fixing bacterium that nodulates Anthyllis vulneraria in mine tailings highly contaminated in zinc, lead and cadmium. To study the mechanisms whereby this bacterium copes with metals, we functionally screened a cosmid genomic library of M. metallidurans for zinc or cadmium tolerance. A cosmid clo...
