Biotic and abiotic signals in pIRs. A Illustrates the pIRs that were either enriched (black arrows) or significantly enriched (green arrows) in at least one category of disease resistance genes, based on permutation of genes across the genome. The four categories of disease resistance genes are CNL: CC-NB-LRR, TNL: TIR-NB-LRR, RLP: Receptor Like Proteins, and RLK: Receptor Like Kinases. Asterisks denote significant categories. B Shows windows with introgression signals with pIRs (above the red line) from V. candicans into V. berlandieri (based on the ARB trio) across chromosome 9. The details show two pIRs that are highly enriched in disease resistance genes in green, with non-disease genes shown in black. C Number of SNPs associated with all 19 bioclimatic variables per species. D Shows the pIRs that were significantly enriched (blue) in at least one of the top three bioclimatic variables. Asterisks denote significant enrichment in pIRs, based on permutation tests. E The diagram shows the distributions of the number of climate-associated SNPs within pIRs based on permutation for the top three bioclimatic variables for the ARC trio. The distributions based on permutations are in black and the observed value is in magenta
