Like most plants, it forms mutualistic symbioses with arbuscular mycorrhizal fungi (AMF), but the nutritional basis of mycorrhiza-responsiveness is largely unknown. Here, we investigated the transcriptional and physiological responses of sorghum to two different AMF species, Rhizophagus irregularis and Funneliformis mosseae, under 16 different conditions of nitrogen (N) and phosphorus (P) supply. Our experiment reveals fine-scale differences between two AMF species in the nutritional interactions with sorghum plants. Physiological and gene expression patterns (ammonium transporters: AMT, phosphate transporters: PHT) indicate the existence of generalist or specialist mycorrhizal pathway. While R. irregularis switched on the mycorrhizal pathway independently of the plant nutritional status, F. mosseae influenced the mycorrhizal pathway depending on the N-to-P plant ratio and soil supply. The differences between both AMF species suggest some AMT and PHT as ideal candidates to develop markers for improving efficiency of nutrient acquisition in sorghum under P and N limitation, and for the selection of plant genotypes.
