Through large-scale transformation analyses, TaMYB72 was identified as a flowering time regulator in wheat. TaMYB72 is a MYB family transcription factor localized to the nucleus. Three TaMYB72 homologs, TaMYB72-A, TaMYB72-B and TaMYB72-D, cloned from hexaploid wheat were mapped to the short arm of the group 6 chromosomes. Under the long-day conditions, over-expression of the TaMYB72 in rice shortened the flowering time by approximately 12 d. Expression analyses suggest that TaMYB72 may function through up-regulation of florigen genes Hd3a and RFT1.
通过大规模的转化分析，TaMYB72 被鉴定为小麦开花时间的调节因子。TaMYB72 是一种定位于细胞核的 MYB 家族转录因子。从六倍体小麦中克隆的三个 TaMYB72 同源物，TaMYB72-A、TaMYB72-B 和 TaMYB72-D，被定位到 6 号染色体的短臂上。在长日照条件下，在水稻中超表达 TaMYB72 可使开花时间缩短约 12 天。表达分析表明，TaMYB72 可能通过上调花形成基因 Hd3a 和 RFT1 来发挥作用。
