摘      要：The MADS-box gene plays an important role in regulating plant growth and *** this study,a SEP3-like MADS-box gene TaSEP3-1 was isolated from bread *** expression patterns of the three homoeologs TaSEP3-A1,TaSEP3-B1,and TaSEP3-D1 were similar,and higher expression levels were detected in floral organs and developing ***3-D1 was located in the nucleus and cytoplasm and possessed transactivation activity in *** sequence polymorphism analysis identified four,three,and four haplotypes of TaSEP3-A1,TaSEP3-B1,and TaSEP3-D1,respectively,and the haplotypes of TaSEP3-D1 had larger effects on agronomic traits than those of TaSEP3-A1 and TaSEP3-B1.D1_h4,significantly associated with heading date,plant height,and other yield-related traits,was the favored haplotype of *** wheat genotypes overexpressing TaSEP3-D1 exhibited delayed heading and reduced plant height,indicating a role in regulating heading date and plant *** results shed light on the role of TaSEP3-D1 in wheat plant *** favored haplotype of TaSEP3-D1 can be applied in breeding to improve plant architecture and yield in wheat.
