Auxin/indole-3-acetic acid (Aux/IAA) proteins function as repressors of auxin response gene expression when auxin concentrations in a cell are low. At elevated auxin concentrations, these repressors are destroyed via the ubiquitin-proteasome pathway,

Auxin signaling is key to many plant growth and developmental processes from embryogenesis to senescence. Most, if not all, of these processes are initiated and/or mediated through auxin-regulated gene expression. Two types of transcription factor fa

Cucumber seedlings show positive gravitropism and bend in the transition zone between the hypocotyl and the root. The peg, a specialized protuberance, develops on the concave side of the bending transition zone. Auxin and the mRNA of an auxin-inducib

Aux/IAA Proteins Contain a Potent Transcriptional Repression Domain

Autor: Shiv B. Tiwari, Gretchen Hagen, Tom J. Guilfoyle

Publikováno v: The Plant Cell. 16:533-543

Aux/IAA proteins are short-lived nuclear proteins that repress expression of primary/early auxin response genes in protoplast transfection assays. Repression is thought to result from Aux/IAA proteins dimerizing with auxin response factor (ARF) trans

A large number of genes involved in lateral root (LR) organogenesis have been identified over the last decade using forward and reverse genetic approaches in Arabidopsis thaliana. Nevertheless, how these genes interact to form a LR regulatory network
