In functional study, overexpression assay was conducted in potato. Interestingly, tuberous swelling along roots was observed in some transgenic potato lines in addition to stem-derived tuber formation. Conclusively, we propose a hypothesis to illustrate the mechanism by which IbMADS1 participates in the initiation of tuberization in sweet potato.
利用解剖切片观察并比较转殖马铃薯与野生型甘薯的根部块状膨大区域,可以发现两者在膨大初期,中柱内含的细胞数皆增多,尤其是木质部细胞出现不正常增生情形,进而扩展中柱区域;因此,我们可以初步推论在甘薯块根发育初期,IbMADS1藉著作用於根部分生组织,尤其是中柱的原始形成层,从而促进细胞分裂,并参与甘薯的初期结薯。
