通过大规模转化分析，发现TaMYB72是小麦开花时间调控因子。TaMYB72是一个MYB家族转录因子，定位于细胞核。从六倍体小麦中克隆到的3个TaMYB72同源物TaMYB72- a、TaMYB72- b和TaMYB72- d定位在第6组染色体短臂上。在长日照条件下，水稻过表达TaMYB72可使开花时间缩短约12 d。表达分析表明TaMYB72可能通过上调成花基因Hd3a和RFT1发挥作用。
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.
