| Outline of Final Research Achievements |
One transporter gene which expression increased 13 times after fertilization was determined by microarray analysis using rice eggs before and after fertilization. The tos mutant of this transporter presented the phenotype of parthenocarpy. Measurement of IAA concentration in ovaries revealed that IAA concentration in Tos mutant was lower than wild type rice plant. Analysis of metal concentrations in plant body revealed that zinc concentration in ovaries of Tos mutant was significantly higher than that of wild type rice plant.
