Figure 6.

Branch root length of 12 lines of B. distachyon from experiment 9 (for detailed conditions, see Supplemental Table S1). A, Branch root length of nodal roots expressed in centimeters (centimeters of axile root)⁻¹ for CNR (red; left axis) and LNR (green; right axis). Error bars represent sem (n = 10). *, Significant difference with Bd21-3 (P < 0.05). B, Branch root length in centimeters (centimeters of LNR)⁻¹ for LNR against total LNR length in meters per plant. Blue circle encompasses lines with similar LNR length but different branching values. Red circle encompasses lines with similar branching but different total LNR length. Error bars represent sem (n = 10).
