| Outline of Final Research Achievements |
The epidermis of shoot organs in plants develops from the outermost layer (L1) of the shoot apical meristem. In higher plants, a pair of homeobox genes, ARABIDOPSIS THALIANA MERISTEM LAYER1 (ATML1) and PROTODERMAL FACTOR2 (PDF2), play an essential role in regulating the expression of L1-specific genes. PDF2/ATML1 contain a START-domain, a putative lipid binding domain. In this research, we found that the outermost-cell-specific lipids are crucial for the epidermal cell differentiation by modulating the activity of key transcription factors.
