Outline of Final Research Achievements

By targeted expression studies, I revealed that MIZ1 indispensible for hydrotropism in Arabidopsis roots functions in cortical cells of the elongation zone. Also, laser-ablation experiments showed that hydrotropic response occurs independently of the root cap and meristem. Novel genes directly involved in hydrotropism were not found by microarray analysis, but I established the yeast two-hybrid system for verifying the MIZ1-interactive proteins.
