✦ Synopsis

The uptake rates of 16 amino acids were measured in leaf discs from Nicotiana tabacum L., cv. Xanthi (wild type) and from two valine-resistant mutants, ValM and Valr-2. For all amino acids tested the uptake rates in ValM were similar to those in the wild type. The Vale-2 mutant showed a reduced uptake of neutral and acidic amino acids, but uptake of the basic amino acids was only slightly lower than in the wild type. It is argued that two systems for amino-acid transport are present: one for neutral and acidic amino acids and the other for basic amino acids. Key words" Amino acid uptake -Leaf (amino acid uptake) -Mutant (valine-resistant) -Nicotiana (amino acid transport) -Transport (membrane) -Valine resistance.

A mutant of Nicotiana plumbaginifolia, CKR1, isolated on the basis of its enhanced resistance to cytokinins was found to have a greater tendency to wilt than the wild type (Blonstein et al., 1991, Planta 183, 244-250). Further characterisation has shown that the wiltiness in the mutant is not caused
