百脉根LjCYC1基因致非洲紫罗兰花形改变

利用农杆菌介导法将百脉根花对称性基因LjCYC1转入非洲紫罗兰，进一步探讨其作用和功能。非洲紫罗兰LjCYC1转化植株的表型发生以下变化：（1）花的对称性明显改变，由辐射对称变为两侧对称，出现频率为14.3%；（2）花瓣向花冠基部裂开，且花瓣数减少，出现频率为57.1%；（3）部分或全部雄蕊花瓣化，出现频率为17.1%；（4）雌蕊花瓣化或退化，出现频率为11.4%。

Flower Shape Changes of African Violets Caused by LjCYC1 Gene in Lotus japonicus

In order to investigate the function of LjCYC1 gene，floral symmetry gene LjCYC1 in Lotus japonicus was transformed into Saintpaulia ionantha，by using Agrobacterium-mediated transformation technology. Phenotypic observations showed as following：(1) The floral symmetry was obviously changed，the flowers of 14.3% transferred from actinomorphy to bilateral symmetry；(2) The corolla of 57.1% flowers crack deeply to the base，and the shape of petals changed，and number of petals reduced；(3) The stamens of 17.1% flowers conversed partially or whole into petal-like structures；(4) The pistil of 11.4% flowers conversed into petal-like structures or degenerated.
