Introduction

In both animals and plants, hormones generally act pleiotropically to regulate growth and development. The phytohormone cytokinin has been linked to a wide array of developmental processes since its identification in the 1950s as a factor, which, in concert with auxin, induced cell division in tobacco tissue. These processes include organ initiation, meristem maintenance, chloroplast development, vascular differentiation, and leaf senescence. Further, cytokinin also plays an important role in the responses to biotic factors, such as pathogen defense and rhizobial symbiosis, and abiotic factors such as cold, drought, and salt stress. How a signal mediates such diverse biological outputs and how these responses are intertwined with other signaling pathways remain fundamental questions in plant biology.

Molecular genetic studies in Arabidopsis thalianahave revealed that cytokinin signaling in this dicot model system is similar to bacterial two-component phosphotransfer...
