Function

function

Probable factor involved in nitrate and phosphate signaling in roots. Integrates nitrate and phosphate starvation responses and adaptation of root architecture, depending on nutrient availabilities. Acts downstream of the nitrate sensor and transporter NPF6.3/NRT1.1. Represses primary root development in response to phosphate deficiency conditions, only when nitrate is present.

Features

Showing features for dna binding.
