() is a kind of edible fruit and could be beneficial as inhibitor for skin ageing process. Majority of root plants have symbiotic associations with arbuscular mycorrhizal fungi (AMF); however, AMF in has never been reported. The objective of this study was to observe AMF colonies and to identify AMF spores in bisbul tree rhizospheres and in potcultured . Roots and soil samples from rhizospheres were collected from three locations in Bogor area. Roots were stained using trypan blue 0.05%. Soil samples were air dried, then parts of them were used for spore isolation and the rest were used for pot cultures. Spores were isolated by wet sieving and decanting method and then continued with centrifugation. The results showed that the structures of AMF colonies in roots were arbuscules, vesicles, coiled hyphae, and internal hyphae. Isolated AMF spores were identified as , .and . This is the first report of mycorrhizal infection in the root of and AMF association with root.AM Fungi, symbiosis,

“…DISCUSSION Our study demonstrates that, at least in one soil, there is considerable diversity among the chitindecomposing actinomycetes associated with spores of a VAM fungus. The cell walls of most fungi, including VAM fungi, contain chitin and these organisms provide one of the major substrates for chitin-decomposing soil actinomycetes (Jensen, 1932;Veldkamp, 1955 ;Williams & Robinson, 1981;Williams, Lanning & Wellington, 1984).Therefore, the demonstration by Bhattacharjee et al (1982), and by us, that actinomycete filaments occur on VAM fungus spore walls is not surprising. The important question to resolve is whether actinomycetes are the primary microorganisms responsible for reducing the growth and survival of VAM fungi in the soil.…”

“…Many of these organisms have been shown to be hyperparasites (Ross & Daniels, 1982), but beneficial organisms may also be present. Fungi (Ross & Daniels, 1982), bacteria (Gerdet-natin & Trappe, 1974) and actinomycetes (Bhattacharjee et al, 1982) have been observed on the surface of VAM fungal spores. A digestive action observed on spore walls was believed to have been caused by actinomycetes (Gerdematin & Trappe, 1974) atid these organisms are the most common of the chititi-decomposing organisms in soil (Veldkamp, 1955).…”

Chitin‐decomposing actinomycetes associated with a vesicular–arbuscular mycorrhizal fungus from a calcareous soil

1989

SUMMARY.Spores of Glomus macrocarpum Tul. & Tul. were sieved from a calcareous, silty clay loam soil, washed in sterile water, and plated on chitin agar for the isolation of actinomycetes. Of the 190 spores examined, 100 were colonized by one or more chitin-decomposing microorganisms: 82"/,, were colonized by actinomycetes, 17% by bacteria, and 1 "o hy fungi. Fifty-otie actitiomycete isolates were classified on the basis of morphological, cultural and biochemical criteria. Tentative identifications to genera and nun-ibers of different isolates are as follows:Streptomvces (29); Nocardia (3); Streptosporangium (1); Strcptovcrticillium (1); Intrasporangium (1); Nocardiodes (1); anci unidentified (15). This is the fit-st study to report the prevalence and diversity of chitin-decotnposing actinomycetes associated with spores of a vesicular-arbuscular mycorrhizal fungus in field soil.
