Abstract
The identity of a mycorrhizal fungus in the roots of achlorophyllous Sciaphila tosaensis was investigated by DNA analysis and examination of the morphology of the association. The morphological features of the mycorrhizal fungus, i. e. aseptate hyphal coils, vesicles, arbuscule-like branching, and degenerate coils were similar to those previously reported for other achlorophyllous plants. Spore-like propagules identified asa glomalean fungus were propagated from root pieces of S. tosaensis in pot culture using alfalfa as the host trap plant. A PCR product was obtained from colonized root of S. tosaensis using the taxon-specific primers, VANS1 and VAGLO. Sequence analysis of the DNA fragment showed it to be almost identical to other Glomus species. Although it has been reported many times that the morphology of mycorrhizal fungi in achlorophyllous plants is quite similar to that of arbuscular mycorrhizal fungi, this is the first report of the isolation and identification of such a fungus itself.
