The Nutrient Response Transcriptional Regulome of Arabidopsis.

ABSTRACT: Plants respond actively to changes in their environment. Variations in nutrient availability elicit substantial transcriptional reprogramming, and we aimed to systematically describe these adjustments and identify the regulators responsible. Using gene coexpression analysis based on 13 different nutrient availability anomalies, we defined and analyzed nutrient stress response signatures. We identified known regulators and could predict functions in nutrient responses for transcriptional regulators previously associated with other processes, thus linking development and environmental interaction. Three of the identified transcriptional regulators, PIF4, HY5, and NF-Y, known from their role in light signaling, targeted a substantial part of the network and may participate in remodeling the g
