Auxin-responsive gene expression: genes, promoters and regulatory factors.
A molecular approach to investigate auxin signaling in plants has led to the identification of several classes of early/primary auxin response genes. Within the promoters of these genes, cis elements that confer auxin responsiveness (referred to as auxin-response elements or AuxREs) have been defined, and a family of trans-acting transcription factors (auxin-response factors or ARFs) that bind with specificity to AuxREs has been characterized. A family of auxin regulated proteins referred to as Aux/IAA proteins also play a key role in regulating these auxin-response genes. Auxin may regulate transcription on early response genes by influencing the types of interactions between ARFs and Aux/IAAs.
