The accumulation of labelled ions was measured in seedlings of Arabidopsis thaliana (L.) Heynh. grown in submerged cultures. Genotypes used were wild type and the nitrate‐uptake mutant B1, which is altered in the uptake of nitrate and chlorate from concentrations above 1 m M when grown under normal conditions. At low and high concentrations of chlorate, chloride, and K + , significantly less radioactivity was accumulated in seedlings of B1 than in seedlings of wild type. The influx of sulphate did not decrease in B1. The results indicate that the effect of the mutation in B1 is restricted to the uptake of monovalent ions.
