Role of membrane transporter encoded by ENT3 gene in transport of ribosylated zeatin form was investigated. Arabidopsis plants of wild type (Columbia) and their ent3 mutants were used for this study. Analysis of cytokinin content in shoots and roots of both genotypes without any impact and after treatment with protonophore carbonyl cyanide m-chlorophenylhydrazone and/or zeatin riboside showed the importance of the transporter for normal transmembrane transport of cytokinins and their uptake by cells.
