| Outline of Final Research Achievements |
In this study, we developed a new gene induction method, which allows cell-specific gene induction in Arabidopsis female gametophytes using heat shock-induced Cre-loxP recombination and female gametophyte-specific promoters. Female gametophyte-specific gene expressions were induced by heat treatment of flower buds of constructed transgenic lines. We also showed induction of cell-specific gene expression by irradiating isolated female gametophytes with the infrared laser. The developed method will be a good tool to analyze functions of proteins involved in the fusion of polar nuclei during female gametophyte development.
