Elemental colocalizations represented by PCA loadings plots based on pixel intensities of elemental maps; Elemental maps were obtained by LA-ICP-MS analysis of cross sections of roots (a,b), stems (c,d) and leaf surfaces (e,f) of commercial (a,c,e) and wild (b,d,f) Saxifraga paniculata. ²⁴Mg, ²⁷Al, ³¹P, ³⁹K, ⁴³Ca, ⁵⁷Fe, ⁶³Cu, ⁶⁶Zn, ⁸⁹Y and ¹⁴⁰Ce were selected for the analysis; P was excluded from (a–c) and Fe from (f) due to acquisition problems; The total number of pixels in each map are: (a) 778 [6]; (b) 1830 [1]; (c) 2717 [20]; (d) 4123 [0]; (e) 11,130 [41]; (f) 10,477 [11]; Number of removed outliers are in indicated in brackets.
