A longitudinal section of an Arabidopsis inflorescence stem

The Arabidopsis inflorescence stem consists of multiple cell layers. Epidermal cells and small cortex cells are viewed in a cryo-planed Arabidopsis inflorescence stem. The sample was treated with hypochlorite to empty out cytoplasmic contents and to view cellulose microfibrils in the cell wall by field emission scanning electron microscopy, a technique first developed in the Wasteneys lab (Sugimoto et al. (2000) Plant Physiol 124(4) :1493-1506).
