| Outline of Final Research Achievements |
Development of flat leaf structure is dependent on the appropriate adaxial-abaxial patterning. as2 rpl4d mutant has a leaf polarity defect in which leaves are strongly abaxialized. Isolation of suppressor mutants for as2 rpl4d, their phenotypic characterizations, and cloning of their responsible genes revealed following mechanisms. Strong leaf abaxialization is induced by upregulation of a NAC transcription factor gene, SUZAKU1 (SZK1). This upregulation is mediated by reduced mRNA level of RPL4D yet the abaxialization phenotype requires the presence of aberrant RPL4D protein. The SZK1 induction is also dependent on a RING finger protein, SZK2, and a ribosomal protein RPL12B.
