Membrane and cell wall dynamics control cell entry of symbiotic bacteria

A key feature of the evolutionary maintained ability to efficiently fix atmospheric nitrogen is the intracellular colonization of rhizobia in nodules. The cellular entry is initiated by an invagination of the plasma membrane demarcating the onset of infection thread (IT) development, the stabilization of the IT and its transcellular passage as well as the release of rhizobia into nodule cells. For this, dynamic modulation of membrane and cell wall pattering and signalling at spatially confined sites is the key. Over the last years we have gained a mechanistic understanding of these processes, which I will summarize to draw a comprehensive picture of intracellular infections in legumes.
