Oo. Lyalin et al., POLYETHYLENE-GLYCOL GHOSTS OF NITELLA CELLS AND THEIR USE IN THE STUDY OF CELL-WALL PROPERTIES, Russian journal of plant physiology, 41(5), 1994, pp. 646-650
A simple method is proposed to produce the ''ghosts'' of Nitella synca
rpa cells. The ghosts are the cell walls devoid of plasma membrane and
are capable of maintaining turgor due to polyethylene glycol confined
inside them. A device is described to record the changes in the thick
ness of intact cells and their ghosts as affected by shifts in ambient
pressure. Examples are given of the ghost responses to osmotic and me
chanical effects. We conclude that this model is promising for the stu
dy of cell wall properties.
