Biomass measurements of Melilotus alba and Macroptilium atropurpureum 35 days post inoculation. (A) Melilotus alba plants were singly or coinoculated with Bacilus simplex (B.s.) and Sinorhizobium meliloti (S.m.); Different letters represent values that differ significantly, p < 0.01. (B) Jittered boxplot. Macroptilium atropurpureum plants were singly or coinoculated with Bacillus simplex (B.s.) and Burkholderia tuberum (B.t). The first coinoculation (1) introduced both bacteria species at the same time, whereas the second (2) was inoculated with B.s. first followed by B.t. inoculation 5 days later. Harvesting was performed as described in Methods. Boxes indicate minimum, maximum, 1st and 3rd quartiles and the median value.
