Observation of abscission zone in fruit pedicels. In our experiments, we found that
formation of fruit stalk abscission zone in transgenic plants were different from wild
type (Fig. 4 A). Therefore, we carried out observation and analysis. The optical
microscope (Olympus-BMF) was used to observe fresh abscission zone in fruit
pedicel materials at B17 and B114 stages of transgenic plants and wild type. Repeat
twice for each observation.
