Abstract:
Adaptation of rhizobia to a symbiotic life style and synthesis of the nitrogen-fixing apparatus are coordinated with nodule development by the microaerobic conditions prevailing in the central nodule tissue. Sensing and transduction of the "low oxygen' signal involves similar regulatory elements in different rhizobia, yet, these are combined in species-specific circuits.
