Phosphorus is an essential macronutrient for plant development and metabolism. Plants have evolved ingenious mechanisms to overcome phosphate (Pi) starvation. However, the molecular mechanisms underlying regulation of shoot and root architectures as well as coordinated utilization of Pi and nitrogen remain largely unclear. Here, we show that Nodulation Signaling Pathway 1 (NSP1) and NSP2 regulate tiller number by promoting the biosynthesis of strigolactones (SLs), which are a class of phytohormones with fundamental effects on plant architecture and environmental responses...
