However the biological and ecological roles of fungal endo- Indole acetic acid phytes still totally unexplored. In this study three different fungal endophytes were isolated from Extracellular enzyme the medicinal plant of Asclepias sinaica and identified as Penicillium chrysogenum Pc_25 Medicinal plants Alternaria alternata Aa_27 and the third fungal strain was described as sterile hyphae Sh_26. It was recorded that these endophytes had various ability to produce several extracellular enzymes including amylase pectinase cellulase gelatinase xylanase and tyrosinase. Their antimicrobial activities against different specific test organisms were investigated as well. In addition both endo- phyte isolates . Sh_26 and Aa_27 were found to promote root growth higher than Pc_25 and con- trol treatments. These fungal isolates had a considerable impact on plant growth parameters including root elongation as a result of ammonia and IAA production. ª 2015 Production and hosting by Elsevier . on behalf of Faculty of Agriculture Ain Shams University.
