In this study, TaSAP7-B, including two AN1 domains, was isolated from B genome of wheat（Triticum aestivum L.）. Sequencing analysis on TaSAP7-B illustrated one In Del（insertion-deletion） and one SNP（single nucleotide polymorphism） in the promoter region while no diversity was observed in the coding region. On the basis of SNP in the promoter region（–260 bp）, a dCAPS（derived cleaved amplified polymorphic sequences） marker SNP-260 was developed for TaSAP7-B. Using a natural population consisting of 262 wheat accessions, significant associations were detected between the marker SNP-260 and agronomic traits, such as plant height（PH）, peduncle length（PL）, length of penultimate internode（LPI）, number of spike per plant（NSP）, and 1 000-grain weight（TGW）. Two genotypes were identified using marker SNP-260 in the natural population. Among them, the genotypes possessing C allele exhibited a higher TGW and shorter PH than the T genotypes. Hence, base C was considered as the superior allele. The dCAPS marker of TaSAP7-B can be instrumental for marker-assisted selection for high grain size and short plant height.展开更多
