摘　　要：百合花色主要由花青苷和类胡萝卜素形成,一般粉色和棕色花中主要成分是花青苷;黄色和橙色花中主要成分是类胡萝卜素;红色是由花青苷和类胡萝卜素共同组成。百合花色的遗传现象比较复杂。目前初步构建了几个群体,通过遗传连锁图谱标记了花色相关位点。百合中花青苷和类胡萝卜素合成代谢途径中的大部分结构基因已经被克隆和研究。花青苷合成途径中的转录因子Lh MYB12调控百合花被片中的花青苷的有无,其转录水平调控花青苷的颜色强度和着色类型。本文总结了百合花朵的着色机理研究,为进一步开展百合花色育种提供了理论参考。Lily flower colors are derived mainly from anthocyanins and carotenoids,and anthocyanins are the major pigment in pink and chocolate brown cultivars,whilst carotenoids in yellow and orange cultivars,and both anthocyanins and carotenoids contribute to red ones. The genetic mechanism and biosynthetic pathway of pigments are complicated in lily. It is documented that several genetic linkage maps of lily populations have been preliminarily constructed,and several quantitative trait locis related with flower color were also mapped. Many structural genes involved in the biosynthesis of anthocyanin and carotenoid have been isolated and identified. The transcription factor Lh MYB12 involved in anthocyanin pathway regulates anthocyanin biosynthesis and determines the presence or absence of anthocyanin pigmentation in tepals,its transcript level affects the intensity and pattern of anthocyanin color. The better understanding on pigment biosynthetic pathway is helpful for breeding to change flower color by engineering the pathways in lily cultivars.
