| Research Abstract |
1. We have identified NA2C and AtNA2C genes for protein phosphatases in tobacco and arabidopsis, respectively, which may be involved in activation of the NACK-PQR pathways that are required for cytokinesis. Results of our recent studies have suggested that AtNA2C is related to asymmetric cell division of meristematic cells. 2. For understanding of a role of the GIG-APC pathway of arabidopsis in cell fate determination, we have sought for new mutants that might modify gig1 phenotypes. We have identified 11 novel mutations. Results of our investigations suggest that GIG1 and UVI4, a homolg of GIG1, both are involved in development of stomata. 3. Since we failed to reproduce the involvement of members of the MAP65 gene family in asymmetric cell division in arabidopsis roots, we postponed experiments with double mutants of genes in the two pathways described above.
