| Outline of Final Research Achievements |
We analyzed korpokkur (kor) mutants which show continuous vegetative growth to elucidate the function of KOR gene.kor mutants continuously produce small leaves during their vegetative growth. The leaves don’t have midrib and the initiation of node / internode structure is delayed in the mutants. Such characters indicate that vegetative phase change does not occur in the mutants. In addition to the character, kor mutants have abnormal cell morphology. KOR gene has been cloned and revealed to encode an unknown single-copied protein in rice. It is expressed in patchy way throughout the rice plant. That indicates KOR gene expression is specific during cell cycle.
From the results in the report, it is revealed that KOR gene is essential to vegetative phase change and proper cellular development.
