Strigolactone released from plant root stimulates germination of root parasitic plants and induces hyphal branching of arbuscular mycorrhizal fungi in the rhizosphere. In plant, strigolactone works as a plant hormone inhibiting shoot branching. It was already reported that phosphorus (P) deficiency promoted but P fertilization suppressed strigolactone exudation. In the present study, we demonstrated that auxin increased strigolactone exudation when rice plants were subjected to P fertilization, while cytokinin decreased strigolactone exudation when rice plants faced to P deficiency.
