a Overview of ions accumulation in shoot of sgn3-3, myb36-2 and sgn3-3 myb36-2 mutants compared to WT using different growth conditions in agar plates (long day, n = 10 individual plants), in hydroponics (short day, n = 6 individual plants) and natural soil (short day, n = 18 for WT, n = 18 for sgn3-3, n = 18 for myb36-2 and n = 13 for sgn3-3 myb36-2). Element concentration was determined by ICP-MS and is available in Supplementary Data 3. Colour code indicates significant changes in accumulation compared with the WT using a two-sided t-test (p < 0.01). b Principal component analysis (PCA) based on the concentration of 20 elements in shoots of plants grown in agar plates. Ellipses show confidence level at a rate of 90%. n = 10 individual plants. c Plots presenting the correlation between the z-scores of elements content in shoots of plants grown in agar plates of WT, myb36-2, sgn3-3 and sgn3-3 myb36-2 against the portion of root length permeable to propidium iodide as determined in Fig. 1d. The black lines show the average and the grey area show the 95% confidence interval (n = 10 individual plants).
