Additional file 3: Figure S1:

Involvement of leaf-to-leaf and leaf-to-blade partitioning. Leaf-to-leaf partitioning and sheath-to-blade partitioning of Na+ are both clearly correlated with SES, though the relationship is weaker than that for SES. Both may be at least partially independent of actual L6 Na+ concentrations. A, SES vs. L6 blade/sheath ratio of Na+ concentrations. B, SES vs. L6/L5 ratio of Na+ concentrations. C, L6 Na+ concentration vs. L6 blade/sheath ratio of Na+ concentrations. D, L6 Na+ concentration vs. L6/L5 ratio of Na+ concentrations. FL478 was the tolerant check.
