is an endemic species of east Asia which is famous for its showy inflorescence and medicinal bulbs. Its inflorescence is a determinate raceme and the flowers bloom synchronously. Morphological observation and time-course transcriptomic analysis were combined to study the process of inflorescence and flower development of . . The results show that the autonomic pathway, GA pathway, and the vernalization pathway are involved in the flower formation pathway of . . A varied ABCDE flowering model was deduced from the main development process. Moreover, it was found that the flowers in different parts of the raceme in . gradually synchronized during development, which is highly important for both evolution and ecology. The results obtained in this work improve our understanding of the process and mechanism of inflorescence and flower development and could be useful for the flowering period regulation and breeding of . .
是一种东亚特有物种，以其艳丽的花序和药用鳞茎而闻名。其花序为有限总状花序，花朵同步开放。结合形态学观察和时间进程转录组分析来研究……的花序和花发育过程。结果表明，自主途径、赤霉素途径和春化途径参与了……的花形成途径。从主要发育过程推导出了一个多样的ABCDE花发育模型。此外，发现……总状花序不同部位的花朵在发育过程中逐渐同步，这对进化和生态都非常重要。这项工作获得的结果增进了我们对花序和花发育过程及机制的理解，可能对……的花期调控和育种有用。
