  abstract = {{S}ome leguminous species of the genus #{A}eschynomene$ are specifically stem-nodulated by photosynthetic bradyrhizobia. {T}o study the effect of bacterial photosynthesis during symbiosis, we generated a photosynthesis-negative mutant of the #{B}radyrhizobium$ sp. strain {ORS}278 symbiont of #{A}eschynomene sensitiva$. {T}he presence of a functional photosynthetic unit in bacterioids and the high expression of the photosynthetic genes observed in stem nodules demonstrate that the bacteria are photosynthetically active during stem symbiosis. {S}tem inoculation by the photosynthetic mutant gave a 50% decrease in stem-nodule number, which reduced nitrogen fixation activity and plant growth in the same proportion. {T}hese results indicate an important role of bacterial photosynthesis in the efficiency of stem nodulation.
