BRX mediates feedback between brassinosteroid levels and auxin signalling in root growth.

Nature - 28 Sept 2006

Mouchel Céline F, Osmont Karen S, Hardtke Christian S

Abstract excerpt

Brassinosteroid and auxin decisively influence plant development, and overlapping transcriptional responses to these phytohormones suggest an interaction between the two pathways. However, whether this reflects direct feedback or merely parallel inputs on common targets is unclear. Here we show that in Arabidopsis roots, this interaction is mediated by BREVIS RADIX (BRX), which is required for optimal root...
