Nodule morphology and ultrastructure of alfalfa inoculated with Rm1021 and the SMc01113::mTn5 mutant. (A) Plants inoculated with either Rm1021 (left) or the SMc01113::mTn5 mutant (right) after 4 weeks growth. (B) Pink nodules induced by Rm1021. (C) Small white nodules induced by the SMc01113::mTn5 strain. (D) Ultrastructure of a pink nodule induced by Rm1021 (bar, 1.0 μM). (E) Ultrastructure of a small white nodule induced by the SMc01113::mTn5 mutant. Bar = 1.0 μm Plant vacuoles (V) are indicated.
