Abstract
Arbuscular mycorrhizae (AM) are the obligate symbionts, forming natural, beneficial relationships with higher plants. About 80% of plants are colonized by AM fungi which belong to Glomeromycota (Family - Endogonaceae). In soil microorganisms, AM fungi are commonly studied because of their capacity to support plant tolerance under polluted and toxic conditions. The current study deals with the exclusive survey of fifteen industrial sites from MIDC, Dombivli (East). The sites were investigated to study diversity of AM fungi with respect to rhizosphere soil analysis for subsequent spore density and identification. Spores of Glomus, Acaulospora, and Gigaspora were observed. The observed species were also detected in root colonization analysis, using standard staining methods. The spore density was highest for Glomus. The species recorded and identified from genus Glomus are G. aggregatum, G. albidum, G. australe, G. deserticola, G. fasciculatum, G. fulvus, G. geosporum, G. intraradices, G. microcarpum, G. multicaule and G. occultum along with species of Acaulospora like A. foveata, A. mellea, A. scrobiculata and Gigaspora margarita.
