Species-wide natural variation in ATPS1. A, Representative schemes of the three types of ATPS1 haplotypes as obtained from the Arabidopsis 1001 Genomes browser. B and C, Sulfate levels (B) and expression of ATPS1 (C) in leaves of individual accessions belonging to three haplotypes according to the number of deletions at ATPS1. D and E, Sulfate levels (D) and expression of ATPS1 (E) in leaves of the three haplotypes of Arabidopsis accessions. Results are presented as means ± sd from three plants. Different letters mark significantly different values at P < 0.05. Accessions without any deletions (Sha allele) are presented in black, those with one deletion are in dark gray, and those with two deletions (Bay allele) are shown in light gray. FW, Fresh weight.
