4 研究展望
通过比较各转录因子在葡萄和其他果实中对于果实大小的调控作用发现果实大小的调控是一个复杂而且持续的过程。目前在以下几个方面的研究还不够深入:(1)果实大小是一个数量性状,在不同的转录因子家族中证实了其对果实大小的作用,但整个调控网络尚不清楚。(2)在果实的发育过程中,激素对果实的调控与转录因子之间的调控存在着某种联系,两者的作用途径也存在一定的交集,但目前研究尚未解析清楚。(3)关于调控果实发育的其他影响因子,作用机制也不清晰。
对于后续果实大小的研究从蛋白作用开始,从转录因子靶蛋白的作用机制上找寻不同作用通路的交点,然后进行整个网络的研究。果实大小是一个数量性状,其影响因素较多,有必要进行主效影响因素的探究,寻找到主效作用因子从而合理构建调控网络。应借鉴利用目前研究较为透彻的思路与方法进行新的转录调控因素的探究,这样才能较好地整体掌握转录调控通路。
