Fig. 8. Lignin histochemical staining. Shown are the seventh and tenth internodes (from the top), of bm128-B3 transgenic and control plants. Plants were sliced into 1-mm free-hand sections from the top region of the internodes and subjected to (A) phloroglucinol-HCl, and (B) potassium permanganate-HCl staining. Note the more intense staining of the control sections.
