Plants benefit from widespread symbiosis with arbuscular mycorrhizal fungi. This symbiosis between plant and fungus aids plants in capturing mineral and micronutrients from the soil. Gutjahr et al. identified a component of an intracellular receptor, the hydrolase DWARF 14 LIKE, required in rice roots for initiating the symbiosis. A similar receptor detects karrikins in smoke that signal opportunity for fireweed to grow after a forest fire.
