Title: Comparison of the responses of corn root tissue to fusicoccin and washing

Abstract

A comparison has been made of the effects of fusicoccin with those of washing on segments of corn (Zea mays L.) root tissue. Both fusicoccin and washing caused increases in K/sup +/(/sup 86/Rb) influx, net H/sup +/ efflux, and electrogenic cell membrane potential, but with no effect on respiration rate. The similarity was most evident with fresh tissue during the initial phases of washing, prior to the developmental changes which augment the anion and general solute transport rates of the tissue. After the development of enhanced transport capacity the proportional response to fusicoccin was much diminished. It is suggested that the fusicoccin-like response to washing may be a manifestation of recovery from injury.
