| Research Abstract |
This project aimed to understand the genetic regulatory systems which contribute to make up multi-cellular body of plants. The project was made up of three different research groups : the advisory group, the research group 1 and the research group 2. The research group 1 and 2 aimed to investigate the systems underlying the meristem formation and maintenance and the organ formation, respectively. The advisory group supported the research groups by sponsoring the meetings and workshops gathering the researchers, published newsletters, and organized the project. By the support of the advisory group, the research groups made a progress as briefly described below.
1. Analysis of a root meristem-defective mutant, hlr, showed that it has a mutation in a subunit of proteosome complex. This is a novel observation showing that programmed protein degradation is required for maintaining the root meristem structure and function. 2. Analysis of NPK1, a MAPKKKinase, and its activation factor, NACK1 kinesin-like protein form a complex and promote cell plate formation at the cell division. 3. A set of genes related to the circadian clock of a short-day plant, rice, was examined. 4. By using synchronized cell culture system of Xinnia and the tip-procedure, a large number of genes were identified which are required for vascular cell formation from leaf cells. Genes required for cell autolysis were cloned. 5. A set of genes were identified which respond to sugar. Mutants showing aberrant sugar-response were isolated from nealy 6,000 activation-tagged lines.
