| Description |
In this study, based on 36,069 high-quality single-nucleotide polymorphisms (SNPs) from 188 sweet, waxy and hybrid corn accessions with relatively great difference in stalk sugar content, 32 genomic regions and 172 genes were detected as being under selection using selective-sweep analysis between sweet and waxy corns. Furthermore, using the agronomic traits and stalk sugar content of 4 environments from 2 years of spring and autumn sowing, the genome-wide association analysis (GWAS) were performed, which identified a total of 92 significant associated SNPs and 37 significant SNPs were simultaneously identified across multiple environments, and the related candidate genes encoding CDPK, MYB, pyruvate dehydrogenase, pectinesterase and so on. |
