Shown are Phloroglucinol-HCl staining images of stem cross-section of 6-month-old wild type and transgenic plants Overexpression of PdWND3A in Populus increases lignin content and reduces glucose content Shown are chemical composition analysis using debarked stem tissues of 6-month-old wild type (WV94) and two transgenic poplar plants (OXPdWND3A-1 and OXPdWND3A-2) * indicates a

Lignin was localized in sections by applying both Mule and Wiesner (phloroglucinol‐HCl) staining according to standard protocols (Monties 1989) Suberin was detected using a saturated alcohol solution of Sudan IV (Sigma‐Aldrich) Stained root sections were examined by bright‐field microscopy Photo documentation of root sections was achieved with a SPOT RT CCD camera and SPOT RT

A similar test can be performed with phloroglucinol-HCl solution which turns red Toluidine Blue is often used to identify Mast cells by virtue of the heparin in their cytoplasmic granules It is also used to stain proteoglycans and glycosaminoglycans in tissues such as cartilage The strongly acidic macromolecular carbohydrates of mast cells and cartilage are coloured red by the blue dye a
