En réponse à une carence en azote dans le sol, les légumineuses sont capables d’interagir avec une bactérie du sol, Rhizobium, pour former un nouvel organe spécifique: la nodosité fixatrice d’azote atmosphérique. Chez la plante modèle des légumineuses Medicago truncatula, le récepteur aux cytokinines MtCRE1 est essentiel pour cette interaction symbiotique. Cependant, trois autres récepteurs aux cytokinines CHASE Histidine Kinase (CHK) existent chez M. truncatula. Les quatre CHKs ont des profils d’expression redondants dans les étapes précoces de la formation des nodosités, et plus divergeant dans les nodosités différenciées, même si MtCRE1 est le plus exprimé. Le locus génomique du plus proche homologue de MtCRE1 chez la plante non-symbioti...
