Abstract:
Summary High resolution scanning electron microscopy was used to obtain images of cortical microtubules and associated structures in onion root tips. Specimens were prepared using a modified quick-freeze deep-etch technique utilising cytosolic extraction with saponin and conductive staining with osmium.Abbreviations DMSO dimethylsulfoxide - HRSEM high resolution scanning electron microscope/microscopy - MTSB microtubule stabilising buffer - TEM transmission electron microscope/microscopy
