| Research Abstract |
This research project has been carried out to reveal the mechanisms of leaf formation in relation to shoot meristem. We identified WAF1 gene that was associated with shoot meriatem maintenance and leaf morphogenesis. WAF1 functions in the regulation of small RNAa. As for temporal regulation of leaf primordium formation, we newly identified PLA3 gene. Together with the results of PLA1 and PLA2, it is indicated that signals from preexisting leaf primordia play important role on the formation of new leaf primordium. We also identified genes that regulate adaxial-abaxial, central-lateral and basal-apical patterns of leaves.
