Abstract excerpt

Plant architecture is a critical agronomic trait directly affecting planting density and crop yield. Phosphate (Pi) starvation in rice (Oryza sativa) leads to a significant reduction in tiller number and a more upright leaf angle. Insensitivity to brassinosteroid (BR) signaling can lead to similar phenotypes. However, the molecular mechanisms underlying how Pi affects plant architecture through brassinosteroid...
