Abstract
By taking advantage of large cell size of Chara corallina we analyzed the membrane depolarization induced by decreased turgor pressure Shimmen in J Plant Res 124639–644 2011 In the present study the response to increased turgor pressure was analyzed When internodes were incubated in media containing 200 mM dimethyl sulfoxide their intracellular osmolality gradually increased and reached a steady level after about 3 h Upon removal of dimethyl sulfoxide turgor pressure quickly increased In response to the increase in turgor pressure the internodes generated a transient membrane depolarization at its nodal end The refractory period was very long and it took about 2 h for full recovery after the depolarizing response Involvement of protein synthesis in recovery from refractoriness was suggested based on experiments using inhibitors
