(A) M. truncatula Jemalong plants inoculated with S. meliloti NRG185 at 28 days postinoculation. (B) Root nodule from plants in panel A. (C) M. truncatula Jemalong plants in a growth pouch inoculated at 10 days after inoculation with S. meliloti NRG185. (D) M. truncatula Jemalong plants inoculated with S. meliloti NRG247 at 28 days postinoculation. (E) Root nodule from plants in panel D. (F) M. truncatula Jemalong plants in a growth pouch inoculated 10 days after inoculation with S. meliloti NRG247. (G) M. truncatula Jemalong A17 plants inoculated with S. meliloti NRG185 exoB::Tn5 (succinoglycan mutant) at 28 days postinoculation; the nodules were identical to those in panel E. (H) Root nodule from M. truncatula Jemalong A17 plants inoculated with S. meliloti TJR41 (Rm41, pEX312), which carries part of the S. meliloti Rm1021 exo (succinoglycan) gene region.
