  abstract = {{H}ere, we present a comparative analysis of the nodulation processes of {A}eschynomene afraspera and {A}. indica that differ in their requirement for {N}od factors ({NF}) to initiate symbiosis with photosynthetic bradyrhizobia. {T}he infection process and nodule organogenesis was examined using the green fluorescent protein labeled {B}radyrhizohium sp. strain {ORS}285 able to nodulate both species. {I}n {A}. indica, when the {NF}-independent strategy is used, bacteria penetrated the root intercellularly between axillary root hairs and invaded the subepidermal cortical cells by invagination of the host cell wall. {W}hereas the first infected cortical cells collapsed, the infected ones immediately beneath kept their integrity and divided repeatedly to form the nodule. {I}n {A}. afraspera, when the {NF}-dependent strategy is used, bacteria entered the plant through epidermal fissures generated by the emergence of lateral roots and spread deeper intercellularly in the root cortex, infecting some cortical cells during their progression. {W}hereas the infected cells of the lower cortical layers divided rapidly to form the nodule, the infected cells of the upper layers gave rise to an outgrowth in which the bacteria remained enclosed in large tubular structures. {T}ogether, two distinct modes of infection and nodule organogenesis coexist in {A}eschynomene legumes, each displaying original features.},
