Figure 6. Root AtHKT1 Expression Is Determinant for Shoot Na+ Accumulation.
Na+ contents were analyzed in shoots of self-grafted Col-0 plants (n = 3), hkt1–1 shoot grafted onto Col-0 roots (n = 14), Col-0 shoot grafted onto hkt1–1 root (n = 9), and self-grafted hkt1–1 plants (n = 3). Presented data are the mean ± SE.
