Cell wall (outer membrane) of bacteroids in nitrogen-fixing peanut nodules

Abstract

Rhizobia in peanut nodules are transformed from rod-shaped cells to extremely large spherical bacteroids. The invading rhizobia shed their outer membranes soon after their release into the host cells. The outer membranes are seen to be peeled off and replaced by new outer membranes before rhizobia are differentiated into nitrogen-fixing bacteroids. Evidence is presented that peanut bacteroids, in spite of their spheroplast-or protoplast-like appearance, do possess both the inner and the outer membrane.
