Figure 7. — Histochemical detection of secondary metabolites and ROS in the galls of Nothotrioza cattleiani. (A–D) Reaction of ferric chloride solution, Nadi and DMACA to total phenolics (A), terpenoids (B) and proanthocyanidins (C and D), respectively. Most intense reactions are observed in the median and inner cortical cells near the vascular bundles (vb), in the outermost cortical cells and in the epidermal cells near the oil glands (og). (E) Reaction of Wiesner's solution to lignins mainly in the outer cortical cells of the chlorophyllous parenchyma (chp), near the oil glands (og). (F and G) Reaction of DAB to ROS mainly in the median and inner cortical cells, vascular bundles (vb) and outermost cortical cells and oil glands (og). Bars: (A, B, and E) 150 µm; (C, D, F and G) 75 µm.
