Molecular mechanisms of auxin action

Curr Opin Plant Biol. 1998 Oct;1(5):434-9. doi: 10.1016/s1369-5266(98)80269-0.


The plant growth hormone auxin has an important role in a variety of plant growth and developmental processes. Identification of transcription factors, some with defined genetic function, has shed new light on the mechanisms of auxin regulated gene expression. In addition, the molecular characterization of genes required for auxin response indicates that regulated protein degradation by the ubiquitin-proteosome pathway has an important function in auxin action.
