Ultrastructural Localization of Polygalacturonase in Ethylene-Stimulated Abscission of Tomato Pedicel Explants
Figure 5
Transmission electron micrographs of tomato pedicel and localization of polygalacturonase (PG) in abscission zone cells by immunogold labeling (8 h). (a) and (b): cortex; (c) and (d): vascular region; (e) and (f): central parenchymatous region (b); (d) and (f) are enlarged photos for the rectangles region in (a), (c), and (e), respectively.
