Figure 6

Transmission electron micrographs of tomato pedicel and localization of polygalacturonase (PG) in abscission zone cells by immunogold labeling (16 h). (a) and (b): cortex; (c) and (d): vascular region; (e) and (f): central parenchymatous region; (g) and (h): vacuole; (b), (d), (f),and (h) are enlarged photos for the rectangles region in (a), (c), (e), and (g), respectively.
