A recent groundbreaking study by Shi et al. reveals an extensive transcriptional regulatory network for arbuscular mycorrhizal (AM) symbiosis in rice. The finding that phosphate starvation response (PHR) transcription factors centrally orchestrate the direct and indirect AM pathways for inorganic phosphate (Pi) uptake in rice opens a wealth of opportunities for plant breeding to enhance nutrient acquisition.
