摘要: 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%。

Abstract: 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.

Key words: Saintpaulia ionantha, Lotus japonicus, LjCYC1, floral symmetry
