Abstract
OBJECTIVE
Phosphorous (P) is one of the essential elements for tree growth in forests. It is beneficial to characterize oxalate secretion by ectomycorrhizal fungi in response to P supply for understanding the mechanism of P mobilization in soils.
METHOD
In the present experiment, the influence of P supplies and inhibitors of Ca2+ signal/anion channel on oxalate efflux in ectomycorrhizal fungi was studied in the pure liquid culture with various P concentrations.
RESULTS
Ectomycorrhizal fungi released a large amount of H+ and organic acids such as oxalate, acetate, malate, citrate and succinate, which are important for mobilization of insoluble P in the soils. Oxalate accounted for 15. 14% to 36. 01% of the total organic acids released by the fungi and was accelerated in culture solution under the condition of low P supply, but inhibited under normal and high P.
CONCLUSION
Ectomycorrhizal fungi released a large amount of H+ and organic acids, particularly oxalate, which might be beneficial to inorganic P mobilization in the soils and improvement of P nutrition for their host plants.
