Effect of phosphate (A–C) and root exudates (D–F) on symbiosis of R. leguminosarum bv. trifolii 24.2 and its derivatives Rt24.2(pBR1) and Rt24.2(pBBR1MCS-2) with clover plants. The tested symbiotic parameters are: the nodule number (A and D), nodule occupancy (B and E) and fresh shoot weight (C and F). Plants were harvested 28 days after inoculation. Given values are averages of three independent experiments with 20 plants for each treatment. For nodule occupancy, values are means ± SD of 12 nodules.
