Exhaustive two-dimensional GWAS-scan for epistasis identifies six significant interactions, representing four unique pairs, associated with the root length mean.

1Name of associated SNP(s) at the epistatic locus as on the Affymetrix single nucleotide polymorphism (SNP) chip (our abbreviation as Chromosome_PositionInBp); 2p-value for the interaction effect of the two loci in the epistatic GWA analysis [40]; 3Probability that the pair is a false-positive when accounting for the small sample-size (SS) [42]. *R2, phenotypic variance explained per pair. Exhaustive two-dimensional GWAS-scan for epistasis identifies six significant interactions, representing four unique pairs, associated with the root length mean.
