Auxins, Cytokinins and Gibberellins Signaling in Plants

Abstract

Relationships among plant growth regulators (PGR) occur at all metabolism levels, from the mutual regulation of their biosynthesis, degradation, transport, and signaling, to the control of the gradient distribution of auxins (Aux) by cytokinins (CKs) or vice-versa. Gene regulation in Aux signalling has become an important point for turning on or off certain sets of genes during environmental stress, plant development, and hormone interaction. Despite the considerable amount of literature regarding Aux biosynthesis, transport, and signalling, few reports available have explored its complex role in epigenetic regulation. In this book chapter, we analyze the interaction of Aux with CKs, their mutual interrelation, and the role played by epigenetic regulation in Aux.
