aMean values for the leaf, stem, and root aliquots from three separate plants of the CC 41 and GU207/H genotypes (n = 3).

bMean value for the duplicate leaf, stem, and root aliquots from a single plant of the Matina 1–7 genotype (n = 1). f  represents the mass fraction of Zn in leaves, stems, and roots relative to the Zn inventory of the total plant. SD represents the standard deviation. 2SD for individual samples represents the analytical precision of the Zn stable isotope data determined from multiple analyses of the Zn isotope standard that bracketed the sample runs.
