  Methanolic, chloroform and aqueous extracts of 11 medicinal plants used in folklore medicine in Saudi Arabia, were investigated for in vitro activity against four pathogenic fungi. The extracts at concentration of 0.5 mL plate-1 showed varying degrees of total inhibition of fungal growth. Extracts from Salvadora persica and Vigna fragrans showed the highest activity, followed by Peganum harmala and Withania somnifera, while Polycarpaea corymbosa demonstrated the least activity, when compared to 25 μg mL-1 Clotrimazole control antibiotic. The fungal strains tested differed significantly in their susceptibility to plant extracts, with complete inhibition in Aspergillus fumigatus and Candida albicans. The plants which exhibited a marked antifungal activity were shown to be rich in alkaloids, flavanoids, tannins and glycosides. These results support the traditional use of these plants in the treatment of some fungal infections.

  Ten ornamental plants belonging to different families from five sites in Khartoum the capital city of Sudan with equivalent environmental pollution were selected to determine the effect of auto-exhaust pollution on their micro morphological traits. The parameters utilized were numbers of stomata/unit area, numbers of epidermal cells/unit area, length and width of stomata, stomata calculated area, L/B ratio of stomata and stomatal indices from upper and lower surface of the fixed leaf which were found distinctive for each locality.

  Methanolic, chloroform and aqueous extracts of 26 medicinal plants used in folklore medicine in Saudi Arabia were screened for in vitro activity against some Gram-positive and Gram-negative pathogenic bacteria using the cup-plate agar diffusion method. The extracts at concentration of 0.1 mL cup showed varying degrees of inhibitory activity against the test organisms. Extracts from Withania somnifera showed the highest activity, followed by Datura stramonium, while Zygophyllum portulacoides demonstrated the least activity when compared to 40 μg mL-1 Ampicillin control antibiotic. The bacteria tested differed significantly in their susceptibility to plant extracts, with Staphylococcus aureus and Bacillus subtilis have been completely inhibited. The plants which exhibited a marked antibacterial activity were shown to be rich in flavonoids, tannins and alkaloids. These results support the traditional use of the plants in the treatment of some bacterial infections.

  Sixteen different localities in Southern area of Saudi Arabia were examined for their fungal mycoflora. A modified soil-dilution plate method was used for isolating the fungi. Sixty four species in twenty two genera were reported. Of these species five were Phycomycetes, ten were Ascomycetes and forty nine were Deuteromycetes. Of the reported species 55 are new records to the Flora of Saudi Arabia and one of these is a new species.

  A preliminary survey was conducted in Saudi Arabia to isolate and identify some endozoic and nematode-trapping fungi of agricultural soils. The study included 12 agricultural areas in the kingdom. Nineteen species were detected and identified for the first time. Nine species were found to be endozoic against some free-living nematodes in soil. Whereas the remaining 10 species were predacious and nematode- trapping of the genus Tylenchus. The use of these fungi in the biological control of plant-parasitic nematodes of different crops and their prevention was discussed in the present study.
