Fig. 1. Genome-wide association analysis of plant vigor of a diverse panel of aus accessions under Zn deficiency.Data was collected at fourth week after transplanting during the peak-stress period.A, Plant growth of tolerant and sensitive accessions under control (+Zn) and Zn deficiency (-Zn). B, Distribution of seed vigor scores. Higher scores indicate higher tolerance to Zn deficiency. C, Manhattan plot. Plots above the threshold line indicate significant association. D, Quantile-quantile plot.
