Genome-wide association study results for SNS and an analysis of the peak on chromosome 7A. a Manhattan plots for SNS. The horizontal line represents the significance threshold. The arrows indicate the location of the main peaks studied. b Genomic locations of four SNP loci and the LD based on paired R2 values between SNPs on chromosome 7A. c Haplotypes detected in 543 accessions based on the four SNPs. d Differences in the SNS among three haplotypes. e Structure of the TraesCS7A01G482000 gene. f Transcriptomic analysis of TraesCS7A01G482000 in the spike during different developmental stages. Gene expression was based on the fragments per kilobase of transcript per million mapped reads (FPKM) value
