Genome-Wide Association Studies Identify Heavy Metal ATPase3 as the Primary Determinant of Natural Variation in Leaf Cadmium in Arabidopsis thaliana

Figure 5

Reciprocal grafting determines that the low leaf Cd phenotype of CS28181 is driven by the root.

Bars represent the leaf Cd concentration of reciprocally grafted A. thaliana CS28181 and Col-0 accessions. NG = Non-grafted plants; SG = Self grafted plants; CS28181/Col-0 = CS28181 shoot grafted onto a Col-0 root; Col-0/CS28181 = Col-0 shoot grafted onto a CS28181 root. Data represent means of leaf Cd concentration ± standard errors (n = 5–14 independent plants per grafting type). Letters above bars indicate statistically different groups using a one-way ANOVA with groupings by Tukey's HSD using a 95% confidence interval.
