Sorghum genome-wide associations with parasite distribution implicate cell-wall and SL-signaling genes. (A) Genome-wide association with parasite HS score, based on 317,294 SNPs with MAF > 0.01 in 2,070 sorghum landraces. SNPs in genomic regions linked to SL biosynthesis/signaling (red), resistance through formation of a mechanical barrier (light blue), or low S. hermonthica germination (orange) are indicated. Germ., germination; mech. res., mechanical resistance. The dashed line represents significance threshold at a FDR of 5%. (B) Geographic distribution of reference and alternate alleles for an SNP (S2_21521798) in a pectinesterase gene (MAF = 0.275). (C) Distribution of parasite HS scores for sorghum accessions segregating for S2_21521798. (D) Geographic distribution of reference and alternate alleles for an SNP (S7_14459084) in a gene homologous to SMAX1 (MAF = 0.014). (E) Distribution of parasite HS scores for sorghum accessions segregating for S7_14459084. Alt, alternate; Ref, reference.
