A comparison between fusicoccin (FC)-induced and washing-induced increase of K+ uptake in maize root segments is reported. K+ uptake rate nearly doubles after 4 h of washing as compared to the rate in the unwashed tissue. The stimulation of K+ uptake by FC is the same (approx. 1.6 micromol x g fresh wt.(('-1)) x 30 min'-1) both in unwashed and in washed tissue. Washing-induced increase of K+ uptake is strongly inhibited if 10('-2) M KCl is present in the washing solution; on the contrary, FC-induced increase of K+ uptake seems independent of the presence of KCl in the medium during the washing period. The inhibition of protein synthesis completely prevents the
