The interaction between legumes and bacteria of rhizobia type results in a beneficial symbiotic relationship characterized by the formation of new root organs, called nodules. Within these nodules the bacteria, released in plant cells, differentiate into bacteroids and fix atmospheric nitrogen through the nitrogenase activity. This mutualistic...

Le décryptage des fonctions géniques chez Medicago truncatula est aujourd'hui facilité par la mise à disposition d'une collection de plus de 21 000 mutants d'insertion du rétrotransposon Tnt1, dans le génome de la lignée sauvage R108, pouvant interrompre de nombreux gènes d'intérêt. Toutefois, chaque plante qui comporte une copie du Tnt1 dans...

Abstract Group VII ethylene response factors (ERF-VII) are plant-specific transcription factors (TFs) known for their role in the activation of hypoxia-responsive genes under low oxygen stress but also in plant endogenous hypoxic niches. However, their function in the microaerophilic nitrogen-fixing nodules of legumes has not yet been...
