We try to understand the mechanism of inflorescence development in Lotus japonicus, the legume model system through the characterization of CEN homologues in it .

本研究选用豆科模式植物百脉根作为研究系统，从CEN 的同源基因入手，对豆科植物的花序发育进行研究。

This paper is the first time that used space flight mutation to deal with the Lotus Japonicus seeds in domestic, and go on research after back to the earth through planting and mutant selection.

本论文是国内首次利用航天诱变的方法对百脉根进行处理，并进行返地后种植、筛选突变体的研究。

The results approved for the first time that we can obtained various Lotus Japonicus mutants through space flight mutation, and mutant frequency was higher, most of the mutations could stable inherit.

研究结果首次证实了百脉根通过航天诱变处理可以得到多种类型的突变体，并且变异频率高、突变可稳定遗传。
