| ID-1 | dnf1-1 | dnf1 | The mutant makes small, white nodules and has defects in nitrogen fixation. It can induce MtLEC4 and ENOD2 but not MtN31, MtCAM1, or MtLB1. The mutant forms infection threads that proceed through the cortical cells and produce limited nodule-like structures. The infection threads are indistinguishable from those of wild-type plants. It is unknown whether bacteria can differentiate into bacteroids. The mutant creates larger nodule-like structures than those induced by early infection mutants. Bacterial penetration into epidermal cells and into the outer cortical cells surrounding the nascent nodule of mutant plants is morphologically indistinguishable from those in wild-type plants. Bacterial colonization of nodule parenchyma cells is also indistinguishable between mutants and wild type. | Inf+Nod+Fix- | FNB | Nod+Fix- | Jemalong A17 | | 4A-17 | dnf1-2 | dnf1 | The mutant makes small, white nodules and has defects in nitrogen fixation.
