 PHT1;1  haplotype connects the P-acquisition phenotypes of Arabidopsis accessions to the soil P contents in their habitats. Comparison of Pi-uptake activity (A) and PHT1;1/2/3 protein level (B) between accessions with different  PHT1;1  haplotypes. Each gray dot represents an individual accession. C, Distribution of two different genotypic accessions and soil P-contents (in purple) on a map of the European Union. Symbols in green are accessions carrying the “GACCT” haplotype, whereas symbols in blue are those with “AGAGC”. D, Comparison of soil P content for two types of accessions: those with the “GACCT” haplotype and those with the “AGAGC” haplotype. The dark purple lines within violin plots represent the 25th percentile, median (dashed), and 75th percentile. The red lines indicate the means of the quantified phenotypes. The  P -value determined by two-sided Student’s  t  test is indicated on the top of each plot. Values in parentheses shown below the SNPs indicate the numbers of accessions assayed.
