Outline of Final Research Achievements

Plant mitochondria are small and numerous in comparison to those of animals. They move around and undergo frequent fission and fusion. To understand why they have such peculiar characters, I screened several Arabidopsis mutants with aberrant morphology, distribution, and number of mitochondria. Some responsible genes were identified and Their molecular mechanisms were analyzed.
