Review: Auxin perception and downstream events ($)
The mechanism by which auxin alters patters of transcription through TIR1s, ARFs and IAA proteins is well established, but less clear is our understanding of how rapid, non-transcriptional auxin responses occur. APB1 was implicated in non-transcriptional responses, but in the past few years evidence for ABP1 involvement has been challenged. Strader and Zhao review the current status of ABP1 research Students should be encouraged to read this review given the important lessons that may be learned from the rise and fall of ABP1. The authors also propose a model in which PIN proteins act as auxin receptors through a signal pathway similar to that of the PHOT1 blue light response. Curr. Opin.
