Cell division cycle 25(CDC25) is a dual-specificity threonine/tyrosine phosphatase, which, in animals, promotes cell cycle progression through activating cyclin-dependent kinases(CDKs). However, the role of plant CDC25 in cell cycle regulation may be nonessential or has been replaced by other factors. Therefore, the function of plant CDC25 remains to be elucidated. In this study, a prokaryotic expression vector for the wheat CDC25 gene Ta CDC25.1-1 AL was constructed and transformed into E. coli. Results fr...
