title: Auxin-cytokinin interactions in higher plants: old problems and new tools.
abstract: The plant hormones auxin and cytokinin interact in a complex manner to control many aspects of growth and differentiation. Recent advances in understanding their metabolism and the cell cycle are now helping to clarify the mechanisms by which these hormones act together to control various physiological and developmental responses. Molecular and genetic tools are being used to reveal interactions between auxin and cytokinin at multiple levels, including mutual regulation of active hormone availability, input into multiple signal transduction pathways, alteration of gene expression, post-translational modifications and direct modulation of enzyme activity.
