a public repository for large-scale measurements of genome, transcriptome, methylome, pathway and phenotype associations in Arabidopsis, designed for facilitating identification of eQTL, emQTL, pathway-mQTL, pathway-phenotype, GWAS, TWAS and EWAS. AtMAD identifies candidate variants/methylations/genes for specific phenotypes or biological processes,and provides many associations that were previously unknown in exploring biological mechanisms.
