| Research Abstract |
The ribosome plays a critical role in leaf morphogenesis in Arabidopsis thaliana. But how the ribosome regulates specific gene expression is not known. In order to assess whether a r-protein gene contributes to the activation or the repression of genes, engineered-RPL4D genes were constructed and introduced into as2 rpl4d double mutant which leaf-polarity was significantly lost. And, the effects of the region-specific expression of RPL4D on the establishment of an abaxial-adaxial polarity were determined. In this project, it was revealed that the action of ribosome in the abaxial and/or the epidermal region play roles in the formation of a leaf polarity.
