| Research Abstract |
The ELONGATA3 (ELO3) gene in Arabidopsis thaliana thatencodes histone acetyltransferase is involved in leaf development. To clarify themechanism by which ELO3 affects the establishment of leaf polarity, we performed geneticanalysis. We found abaxial identity genes, ETTIN (ETT) and ARF4, were responsible fordefects in leaf adaxial-abaxial polarity in as2 elo3 mutant plants. We analyzed expressionmicroarray data with as2 elo3 and as2 eal to search for genes downstream of ELO3 and AS2. We found cytokinin biosynthesis genes and cell cycle related genes might functiondownstream of ETT.
