Fig. 3From: QTL and candidate genes associated with leaf anion concentrations in response to phosphate supply in Arabidopsis thalianaHapMap/GWA mapping using the multi-trait mixed model (MTMM) approach showing the −log10(P) values (Y-axis), for all SNPs (X-axis) The measured traits are rosette dry weight (a), and leaf Pi concentrations (b), Pi use efficiency (c), and leaf sulphate concentration (d). SNPs associated with candidate genes listed in Table 4 are indicated with vertical black lines. In each panel, the SNPs corresponding to the five Arabidopsis chromosomes are indicated in alternating blue/purple colours, with the horizontal axes indicating genome sequence positions. The −log10(P) arbitrary significance threshold of 4 is indicated with a horizontal dashed lineBack to article page
