Structural similarity of the membrane envelopes of rhizobial bacteroids and the host plasma membrane as revealed by freeze-fracturing.

摘要: The freeze-fracture technique was used to study the host plasma membrane and envelope of bacteroids in rhizobial root nodules three host-rhizobium combinations. In all combinations studied, envelopes are structurally similar their membrane. However, appears be reversed, because number arrangement particles outer fractured face (face A, concave) inner B, convex) seen, respectively, at an early stage. This reversion surface is consistent with hypothesis that derived from during endocytotic engulfment.
