Figure (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Studying the potential of hundreds of plant transcription factors to turn on and off genes allows scientists to annotate regulatory activity in previously described gene networks. This will help scientists understand how large groups of transcription factors regulate their target genes during drought stress and varying nutrient availability.
