GWASs for 21 traits under normal (1,000 µM) and high Mg²⁺ (10,000 µM) conditions. The x-axis is the chromosomal coordinates for Arabidopsis, the y-axis represents p-value. The GWASs hits observed at high Mg²⁺ supply were presented on the top; the hits observed at normal Mg²⁺ were represented at the bottom panel (A). GWAS hits and chromosome were represented by different symbols and coloured, respectively. GWAS hits were shared between normal and high Mg²⁺ were ordered by their longitudinal (x-axis) position. A SNP GWAS hit was defined as the one had −log10(p) > 6.15. (B) Total number of traits that were scared for SNPs with log10(p) > 6.15. The x-axis represents scared traits for Arabidopsis, the y-axis is the p-value. Blue and Red lines represent normal and high Mg²⁺, respectively. (C) Overlap between total number SNP hits for 21 traits at normal and high Mg²⁺. Venn diagrams display overlap between SNP number at normal Mg²⁺ (blue) and high Mg²⁺ (red).
