摘要:
CsBLH7与CsKNAT4分别属于BELL类蛋白与KNOX类蛋白,可能与植物器官形态建成密切相关,但目前几乎没有关于CsBLH7与CsKNAT4蛋白互作的深入研究报道。采用酵母双杂交初步确定CsBLH7与CsKNAT4能够在细胞体内互作,形成BLH7-KNAT4蛋白复合物。双分子荧光互补(BiFC)进一步确定了这种互作关系。原生质体瞬时转染试验结果表明,CsBLH7与CsKNAT4分别为转录抑制因子与转录激活因子。同时,针对35S:CsBLH7、35S:CsKNAT4材料的形态分析结果表明,下胚轴细胞长度分别缩短与伸长,这与它们的转录活性相适应。再者,35S:CsBLH7、35S:CsKNAT4遗传材料的赤霉素合成酶基因分别下调与上调。研究结果表明,BLH7-KNAT4可能是通过调节赤霉素合成来调控下胚轴细胞长度,对揭示CsBLH7和CsKNAT4调控植物形态建成分子机理具有重要意义。
