Abstract
In 2006 the expeditions of Operation Wallacea were operated for the second time in Egypt in which Saint Katherine and Ras Mohamed Protectorates were screened. Diversity of arbuscular mycorrhizal fungi was studied for the first time in Saint Katherine Protectorate. Three hundred roots and rhizospheric soils of 35 plant species belonging to 16 families from 60 sites at different elevation wadis were collected and examined. Seven taxa, three genera, three families, two orders, one class and one phylum were encountered from all sites according to the scheme proposed by Kirk et aL (2001). On the generic level, Glomus was the dominant genus in rhizospheric soils while Glomus clavisporum and G. etunicatum were the dominant species associated with plant species examined. On the other hand G. invermaium was recorded in 110 rhizospheric soils out of 300 samples collected from different wadis. Plant species recorded in the mid elevation wadis had the highest percentage of infection and spore number followed by those of highelevation wadis, while those of low elevation wadis showed the lowest percentage of infection and spores number. The data obtained were subjected to multivariate analysis by using Canonical Correspondence Analysis to find out the relationship between arbuscular mycorrhizal fungi and environmental variables.
