| Research Abstract |
We have isolated the pid enhancer mutants, macchi-bou 2 an4. MAB4 is a member of NPH3 and function to control the endocytosis of PIN proteins, which is an Auxin efflux carrier. MAB 2 is a member of CDK8 sub-complex to function a transcription repressor worked with Mediator complex. This protein suppressed the ARF transcription factor activity by making big protein complex with AUN/IAA and TOPLESS. We also isolated the enhancer of uni-1D, and isolated the enhancer genes by a map base cloning and by using next generation sequencer. One of the enhancers is erecta (er), which expressed without a shoot apical meristem but affected the maintenance of stem cells in it with the two other family members to affect the cytokinin-signaling pathway. ER, which expressed in the phloem, is important for the inflorescence stem elongation and the small peptides EPFL4 and 6 expressed in endoderm cells function as a ligand in this process.
