Research Abstract

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
