Auxin signals--turning genes on and turning cells around

Curr Opin Plant Biol. 2004 Oct;7(5):553-63. doi: 10.1016/j.pbi.2004.07.016.


The extremely wide spectrum of the plant processes that are influenced by auxin raises the question of how signals conveyed by a single molecule can trigger such a variety of responses. Although many aspects of auxin function remain elusive, others have become genetically tractable. The identification of crucial genes in auxin signal transduction and auxin transport in the past few years has led to molecularly testable concepts of how auxin signals regulate gene activities in individual cells, and how the polar transport of auxin could impact on patterning processes throughout the plant.
