Etiolated 'Alaska' pea (P. sativum cv. Alaska) stem sections (10 mm) undergo cellular swelling, with attendant alterations in the cell-wall microfibrillar pattern when treated for 24 h with 25 ppm ethylene. In addition, the ethylene-treated tissue exhibits altered morphology in terms of having intercellular spaces with microfibrillar orientation similar to that of the cell-walls. Ethylene-treated tissue exhibits a ring-shaped nucleolus in comparison to the normal, more compact type of nucleolus, usually present in nuclei.
