Abstract

Nitrogen fixation in the Rhizobium-legume symbiosis is an energy demanding process. The plant supplies energy to the bacteroid and receives in return, fixed nitrogen. C4-dicarboxylates are considered to be the compounds which are provided by the plant. These C4-dicarboxylates have to pass two barriers, the peribacteroid and the bacteroid membrane. In recent years, the investigations were focussed on the transport process through the bacteroid membrane. This transport process is particularly well investigated in Rhizobium leguminosarum (4,5,6) and Rhizobium meliloti (1,7,8,9).
