| Research Abstract |
In Cyrtanthus mackenii, the sperm cells showed structural dimorphism, and differences in microtubule accumulation between the pair of sperm cells arose during the process of cortical microtubule reorganization. As results from EST analysis for elucidation of molecular mechanisms on the sperm dimorphism, the candidate genes with changes in expression during sperm cell formation were listed up. Male gametes irradiated heavy ion beam had a potential to use for the study of sperm cell formation. It was also revealed that the generative cells recognized and managed genomic lesions during the pollen tube growth.
