Arbuscular mycorrhizal fungi mediated uptake of lanthanum in Chinese milk vetch (Astragalus sinicus L.).
Chemosphere. 2007 Jul; 68(8):1548-55.C

Abstract

A glasshouse experiment was carried out to study the effect of mycorrhizal formation by Gigaspora margarita, Glomus intraradices or Acaulospora laevis on plant growth and lanthanum (La) uptake of Astragalus sinicus L. in soils spiked with La at five levels (0, 1, 5, 10 and 20 mg kg(-1)). La application decreased mycorrhizal infection frequency and activity of fungal succinate dehydrogenase and alkaline phosphatase. Increasing La concentrations in soil led to increased La accumulation in tissues of both mycorrhizal and non-mycorrhizal plants, but inoculation with Gig. margarita or G. intraradices reduced La concentrations in shoots and roots at higher concentrations of La in the soil. Plant biomass and P concentrations in shoots and roots were reduced by La application, but increased by inoculation with Gig. margarita or G. intraradices. The results showed that appropriate AM fungi colonization could be effective in alleviating La toxicity in A. sinicus.
