Molecular mechanisms of leaf movement in Mimosa pudica

为了了解敏感植物含羞草（Mimosa pudica）对外界刺激的地震运动的适应意义，我们尝试用EMS和快中子分离突变体。即使筛选了5000 M2种子，也没有获得运动缺陷的突变体。另一方面，我们建立了一种针对反向遗传方法分离运动突变体的转化方法。这项新技术将为今后地震运动的分子机制和演化的研究提供有益的依据

To understand the adaptive significance of the seismonastic movemnet in response to external stimuli in the sensitive plant Mimosa pudica, we tried to isolate mutants with EMS and fast neutron. Evern after screening of 5000 M2 seeds, we could not obtain mutants with defect in the movement. On the other hand, we established a method for tranformation to aim reverse-genetic approach to isolate movement mutants. This new technique will be useful for future study on the molecular mechanisms and evolution of the seismonastic movement
