Phosphorus (P) is an essential element required for plant growth and development, but it is also the most limiting nutrient for plant growth besides Nitrogen (N).Plants have developed many highly specialized physiological, biochemical and molecular mechanisms to acquire and utilize P from the environment, and the activation of specific genes during phosphorus starvation seems to be an essential and universal phenomenon in all organisms.Among all these specific genes, transcription factor genes play an important role in responding to deficient-P cue in plants; for example, AtPHR1, the first phosphorus starvation related transcription factor gene in plant.It was proved that the AtPHR1 signaling pathway in Arabidopsis could regulate the expression of genes implicated in phosphorus remobilization, transport, homeostasis and anthocyanin biosynthesis.
