Since the membrane lipid matrix is not a barrier for O2 [17], the PBM function is the formation of the compartment intended primarily for physical separation of bacteroids, but not to limit the flow of oxygen for them which, as it is well known, dramatically affect the activity of the bacteroid nitrogenase.
Studies concerning nodule physiology and nodule functioning specified that the bacteria in bacteroids forms are surrounded in plant membranes resulting in the formation of symbiosomes [138].

Nitrogen that is fixed by the bacteroids enters the plant's vascular system and can be transported throughout the plant.
Brewin (1991) argues that the symbiosome of nodules has the potential to develop into a lyric vesicle by a decrease in pH that is due to a decrease of nitrogen-fixation products leading ultimately to the death of the bacteroids. A model involving "nod-ons" and "nod-offs" to explain relationships between nodulation and plant defense reactions has been presented by Mellor and Collinge (1995).
