| Research Abstract |
The constitutive active R-protein, uni-1D, induced abnormal morphogenesis in Arabidopsis shoot. We have isolated suppressors of uni-1D. One of them encodes RPT2, which is a component of 26S proteasome and binds directly to UNI. Erecta, which is a receptor kinase in a plasma membrane, is also one of the suppressors. ER family genes expressed outside of SAM, however, affect the SAM activity. ER expressed in phloem affect the inflorescence stem elongation and the EPFL4 and 6, both of which expressed in endoderm cells, function as a ligand in this process.
