Experiments using inoculation into Aeschynomene indica performed with Agromonas oligotrophica S58, Bradyrhizobium sp. ORS278, Bradyrhizobium sp. BTAi1, and other soil isolates (A. oligotrophica S42, S55, S72, and S80) (31 DAI). Plants were grown under nitrogen-free conditions. (A) Photographs showing plant phenotypes. (B) Whole-plant fresh weights determined from three replicates. Statistical significance was calculated with Student's t test for differences between inoculated and uninoculated plant results. *, P < 0.05; **, P < 0.01. (C) Photographs showing root nodules. non, uninoculated controls.
