Micropropagated, rooted, and calli explants of Casuarina equisetifolia L. were inoculated with Frankia UGL 020605S and the arbuscular mycorrhizal fungus (AMF) Glomus mosseae, in single and dual co-culture, in vitro. Different micropropagation media formulations were evaluated for their capacity to stimulate germination of G. mosseae spores and growth of Frankia. Murashige and Skoog basal nutrient (half strength) medium, supplemented with 6-benzylaminopurine (BAP), 2,4-dichlorophenoxyacetic acid (2,4-D), and pyruvate was selected for the in vitro co-culture of C. equisetifolia callus explants, G. mosseae, and Frankia. This medium (M4) supported 70% AMF spore germination with 44 and 34% of the germinating spores producing single and branched hyphal strands, respectively. Hoaglands (quarter strength, modified by Hoaglands and Arnon (1950)) nutrient medium (M5) with no supplements was selected for the in vitro co-culture of rooted C. equisetifolia explants, G. mosseae, and Frankia and supported 57% AMF spore germination with 29 and 40% of the germinating spores producing single and branched hyphal strands, respectively. Both media supported significant growth of Frankia. In both cases agar was substituted with Terragreen(r). AMF appressoria and intercellular hyphae were observed in rooted C. equisetifolia at 28 days; arbuscule formation occurred at 56 days postinoculation. Frankia infection was evident after 28 days. This was observed in both dual and single in vitro co-cultures. No specific immunofluorescent or immunogold reactions to monoclonal antibodies (mABs) anti-Frankia < 8C5 > and anti-G. mosseae < F5G5 > were evident in C. equisetifolia callus explants.Key words: arbuscular mycorrhizal fungi (AMF), Frankia, Casuarina, micropropagation, immunofluorescent labelling.

A greenhouse experiment was conducted to investigate the effects of the arbuscular mycorrhizal fungus Glomus mosseae on growth, metal accumulation and translocation of Festuca arundinacea for the phytostabilization of lead/zinc tailings in this study. The results showed that mycorrhizal inoculation substantially enhanced the growth of F. arundinacea and significantly decreased Pb and Cd concentrations in shoots. The bioconcentration factor and translocation factor values of Pb, Zn, Cu and Cd of F. arundinacea were much lower than 1, and inoculation further inhibited Pb, Cu and Cd translocation from roots into shoots, while enhanced Zn translocation. These results suggested that F. arundinacea inoculated with mycorrhizal might be a potential measure for revegetation of Pb/Zn tailings, especial for Pb, Cu and Cd stabilization, in northern China.
