A Pi-responsive GRAS transcription factor regulates PmSPX1 promoter activity in Pinus massoniana
Phosphate (Pi) deficiency is a major environmental constraint limiting plant growth and forest productivity. Although SPX proteins are central regulators of phosphate homeostasis, the upstream transcriptional mechanisms controlling SPX1 expression in conifers remain poorly understood. Here, yeast one-hybrid (Y1H)...
