Expression study during abscission induction. Expression analysis in seed (solid triangle, continuous line), cortex (open triangle, dashed line), peduncle (solid square, dotted line) and AZ (open square, dashed-dotted line) performed by RT-PCR during abscission induction from 15 to 22 days APF. Samples were collected after triggering abscission with BA 15 days APF (time 0) and 3, 5 and 7 days later. Results are presented as folds induction compared to the T0 of the ratio between the expression level in the abscising fruitlets and in the persistent ones, corrected for the internal control (ubiquitin).
