| Outline of Final Research Achievements |
Transcription factor PAT2 was found the causal gene of parthenocarpy in tomato. I identified target gene that was regulated by transcription factor PAT2 in order to analyze molecular mechanism of parthenocapy. Pat2 expression was decreased and GA3ox one, that is biosynthesis of active GA, was increased by auxin treatment using quantitative PCR in tomato ovary. Furthermore, Pat2 expression was decreased and GA3ox one was increased during developmental stage of ovary. These results indicated that PAT2 suppress GA3ox transcription and indicated that agricultural auxin treatment to tomato flower is this event.
