Abstract excerpt

The directional and sequential flow of cytokinin in plants is organized by a complex network of transporters. Genes involved in several aspects of cytokinin transport have been characterized; however, much of the elaborate system remains elusive. In this study, we used a transient expression system in tobacco (Nicotiana benthamiana) leaves to screen Arabidopsis (Arabidopsis thaliana) transporter genes and...
