Nutrients Exchanged between Plant and Bacteroid
Flow of molecules exchanged during symbiosis between plant and bacteroid. PM represents the peribacteroid membrane. The exchange of nutrients includes some amino acids whose evidence has been recently reported [6]. The presence of myo-inositol has been observed, but its source is unknown.
