Abstract

Differential changes in the distribution of potassium between cytoplasm and vacuole may be an important response of plants to K+ deficiency. Leigh and Wyn-Jones (1984) suggested that as tissue K+ concentration declines, the K+ concentration in the cytoplasm will remain constant while that in the vacuole will decrease. They proposed that decreases in cytoplasmic K+ concentration would only be observed at low tissue K+ concentrations and that growth would decline in response to these decreases. Evidence for such differential behaviour of the cytoplasmic and vacuolar K+ pools in barley leaf cells has now been obtained using X-ray microanalysis.
