| Outline of Final Research Achievements |
Focusing on flavonoid distribution within plant tissues and/or plant cells, survival, growth rate, electron spin resonance, and chromosomal aberrations were investigated in Arabidopsis exposed to gamma-rays. The results suggest that seed-coat specific flavonoid mutants were more sensitive than wild type when gamma-rays were exposed to mature seeds. In additions, a new experimental system to directly visualize mutations in certain genes was established.
