Figure 2From: Specialization-generalization trade-off in a Bradyrhizobium symbiosis with wild legume hostsAverage number of nodules produced by each Bradyrhizobium genotype on each host species. Untransformed data. A) A. strigosus. B) L. bicolor. Error bars represent ± 1 standard error. Solid grey bars represent bacteria originally isolated from A. strigosus and A. heermannii nodules (A bacterial group); solid black bars represent bacteria harvested from L. bicolor and L. arboreus nodules (L bacterial group).Back to article page
