Arbuscular mycorrhizal symbioses alleviating salt stress in maize is associated with a decline in root-to-leaf gradient of Na+/K+ ratio
Abstract Background Inoculation of arbuscular mycorrhizal (AM) fungi has the potential to alleviate salt stress in host plants through the mitigation of ionic imbalance.However, inoculation effects vary, and the underlying mechanisms remain unclear.Two Youth maize genotypes (JD52, salt-tolerant with large root system, and FSY1, salt-sensitive with
