Figure 3
A region of approximately 280 kpb in chromosome 3 where a SNP significantly associated with borer kernel resistance (KR) has been found. The red points represent the P-values of the SNPs in the region mentioned above. The orange strip indicates the location of the SNP significantly associated with KR and the dark blue strips indicate genomic locations in LD (r 2 > 0.2) with the SNP significantly associated with KR. The solid black line and the green rectangle indicate the intronic and exonic region of the cystatin1 gene, respectively. The SNP significantly associated with KR herein is in LD with the exonic region of the cystatin1 gene, which encodes a maize cysteine proteinase inhibitor involved in plant resistance to insects.
