2. The functional analysis of AUXIN RESPONSE FACTORS involved in fruit set of Tomato Auxin & Fruit Set

3. Auxin Response Factor (ARF) are modulated after pollination, but not after GA 3 -treatment. Auxin and fruit set (Maaike de Jong) 79 69 RNAi mediated gene silencing, interacting IAA/AUX factors Hormone Signaling in Fruit Development

4. Model Auxin Response Factors (Woodward; plant cell 2005, 17)

5. Silencing ARF genes clone 69

6. Silencing ARF genes p35S::clone 79 RNAi

7. p35S::clone 79 RNAi “Valentine tomato” Conclusions Fruit set seems to be regulated through ARF factors, that might mediate a primary signal (of embryonic origin) that induces fruit set
