MR tests for the association between the gene expression and a drought tolerance phenotype. a Manhattan plot for the MR test. Each point represents an individual gene. The y-axis is the log10 (P) value of MR test significance. The most significant SNP for each gene among the three water regimes is presented. b Allelic comparison of gene expression level and survival rate for nine candidate genes (indicated by arrows in a) based on the lead SNP of eQTLs
