摘要： Desert ephemeral plants play a key role in desert ecosystem stability and environmental conservation. To determine the effect of indigenous arbuscular mycorrhizal (AM) fungi on the growth and P uptake of the desert ephemeral Plantago minuta, we conducted two on-site experiments in the Gurbantunggut Desert. The co-development of a pre-isolated indigenous AM fungus, Glomus etunicatum, with the ephemeral was also investigated. The results showed that both the single fungus and the indigenous AM fungal community enhanced the growth and P uptake of P. minuta. The phenological phases of P. minuta were highly consistent with the phases of the indigenous AM fungus, G. etunicatum, indicating that both symbiotic partners seem to be able to sense the changes in local weather, which might be an important trait for the survival of both plant and fungus in desert environments. The development of host plant and indigenous AM fungi were interdependent in the desert.
