Mycoflora associated withHyoscyamus muticusgrowing under an extremely arid desert environment (Aswan region, Egypt)

Abstract

Hyoscyamus muticus L. (Egyptian henbane) is one of the desert medicinal plants of family Solanaceae. The plant produces pharmaceutically important compounds (tropane alkaloids) as secondary metabolites. In the present study, we describe mycoflora of H. muticus grown in four different locations in Egyptian southern desert (Aswan region): Aswan university campus, Wadi Allaqi down stream part, Aswan airport road, and Sahari city. Eighty-one species and two varieties belonging to 31 genera were isolated from soils surrounding H. muticus plants, the surface of the plants, and inside the plants as endophytic fungi. Aspergillus was the most common genus in all study areas. The highest number of genera and species of fungi were recorded in Aswan university campus followed by Aswan airport road. Fungal diversity analysis revealed that these two locations have higher fungal diversity compared to other two locations. A higher number of fungal species were isolated from rhizosphere soil and rhizoplane than from non-rhizosphere and other plant organs. Endophytic fungi were isolated from all plant parts of H. muticus. Communications between H. muticus plants and fungi under desert conditions both in rhizosphere and inside the plant are deduced.

Emerging Anticancer Potentials of Goniothalamin and Its Molecular Mechanisms

“…Analytical technique using HPLC-DAD was developed and used to quantify the bioactive components of each extract as marker compounds. Preparation of the herb and the HPLC setup varied as per individual laboratory set up [48, 49]. …”

Antioxidant, antimicrobial and antifeedant activity of phenolic compounds accumulated in Hyoscyamus muticus L.

“…On the other hand, in the current study, the absence of antifungal activity in H. muticus extract is a reasonable result (Figures 3 and 4). This is because; it was found that in nature, many fungal species, including endophytic fungi reside in H. muticus (El-Zayat et al, 2008). The results of the antifeedant potential of the methanol extract of H. muticus are tabulated in Table 5, showing that the methanolic extract of H. muticus exhibited antifeedant effect on the 4th instar larvae of S. littoralis.…”

Microfungal‐community diversity in Zygophyllum dumosum and Hammada scoparia root zones in the northern Negev Desert

“…For instance, the unique species collected beneath Z. dumosum throughout the study period were also isolated by Grishkan et al [21,23,24] and Grishkan and Nevo [22] from either shady or open areas in other regions of Israel. However, four species collected beneath H. scoparia, i.e., Drechslera neergaardii, Humicola sp., Penicillium viridicatum, and Ulocladium tuberculatum, were rarely reported in the previous studies undertaken in Israel [21][22][23][24]33] or other areas of the Middle East [13,14,30]. Since the composition of compounds in the litter and root exudates of H. scoparia is still unclear, it was, therefore, impossible to determine the correlations between the aforementioned microfungal species and H. scoparia.…”

“…A small amount of information enabled us to detect the influence of different plant species on microfungal taxonomic diversity in the root zones under arid conditions [13] in spite of the fact that few investigations have been undertaken in the Middle East [14,21,22,30].…”
