Our laboratory has been investigating why injury or shock to corn roots causes the plasmamembrane to become “leaky”, inhibits H+-pumping and active ion influx, and depolarizes the cell (Gronewald et al 1979, Cheeseman and Hanson 1980, Gronewald and Hanson 1980, 1982, Chastain et al 1981, Chastain and Hanson 1982). In recent years this investigation has come to focus on a role for Ca2+ as the agent for signaling injury (Zocchi and Hanson 1982, Zocchi et al 1983, Hanson 1984). Our working hypothesis has been that schematically illustrated in Fig. 1.
