Therefore, we here select some typical species from Plantaginaceae and Gesneriaceae to carry out comparative studies on the expression pattern and regulation mechanism of CYC-like genes controlling floral symmetry.

• 因此,我们选择车前科和苦苣苔科中与金鱼草较近缘的典型类群地黄属和非洲紫罗兰属作为研究对象,针对它们在花对称性形成方面区别于金鱼草的不同式样,开展这些类群中花对称性主控基因CYCLOIDEA(CYC)类基因的进化发育生物学研究。
