Calcium-Based Interactions of Symbiotic Partners in Legumes: Role of Peribacteroid Membrane

Calcium-Based Interactions of Symbiotic Partners in Legumes: Role of Peribacteroid Membrane Based on experimental evidence, a concept is formulated that mutualistic relationships between pro- and eukaryotic cells during nitrogen-fixing legume–rhizobia symbiosis rely both on selective transfer of metabolites and ion transport, Ca2+ in particular, across the peribacteroid membrane (PBM). PBM in the nitrogen-fixing cells of yellow lupine (Lupinus luteus L.) and broad bean (Vicia faba L.) is endowed with a calcium-translocating ATPase that pumps Ca2+ into the symbiosome. This pumping ensures, on the one hand, calcium homeostasis in the cytosol of infected plant cells and, on the other hand, it optimizes Ca2+ level in symbiosomes, first of all in the bacteroids, because Ca2+ is one of the main factors controlling their nitrogenase activity. The balance between the symbiotic partners and the maintenance of optimal Ca2+ level in the bacteroids also depends on passive Ca2+ efflux from symbiosomes to the plant cell cytosol via calcium channels. The Ca2+-transporting mechanisms residing at PBM are characterized. Russian Journal of Plant Physiology Springer Journals
