| 1 | Diversity of endophytic fungi associated with Hedychium spicatum Ham ex Sm.and their antifungal activity against the phytopathogen Alternaria solani显示文摘Twenty eight strains of endophytic fungi including sterile mycelia were isolated from the leaf,rhizome and roots of Hedychium spicatum Ham ex.Sm.Majority of the endophytic fungi isolated belonged to the phylum Ascomycota which accounted of about 84%.The endophytic assemblage was dominated by the class Sordariomycetes.Endophytic fungal genera such as Fusarium and Penicillium were found to be common to all the plant parts.Diversity of endophytic fungi was found to be highest in the roots(H’=2.43).Mucor hiemalis,Penicillium sp.,Penicillium expansum,P.simplicissimum,Phoma medicaginis,Trichoderma sp.and T.gamsii showed above 60%inhibition against the phytopathogen Alternaria solani. | Sarma P Dkhar MS Kayang H Kumar M Dubey NK Raghuwanshi R | 2020 | Studies in Fungi2020，5，1： | 0 |
| 2 | Endophytic fungal diversity of endemic carnivorous plant Nepenthes khasiana in Meghalaya,India显示文摘The present investigation deals with the isolation of endophytic fungi from leaf,stem,root and pitcher cup tissue segments of the endemic carnivorous plant Nepenthes khaisana collected from its natural habitat for a period of one year at monthly intervals.Out of 576 tissue segments inoculated,a total of 39 fungal endophytes along with mycelia sterilia were isolated from the host plant.To assess the diversity of fungal endophytes,the colonization frequency(%CF)was first recorded using past software and MS excel.The fungal isolates were mainly composed of the phylum Ascomycota,followed by Zygomycota and Oomycota.The highest percentage colonization frequency on an average of three replicates were recorded in pitcher cup tissues followed by root,stem and least was recorded in leaf of the host plant.Among the isolates,Globisporangium irregulare(83.33%)showed high%CF in leaf,Juxtiphoma eupyrena(83.33%)reported to have maximum%CF in the stem,Talaromyces ruber(66.66%)was recorded high%CF in root and mycelia sterilia(white)were showed the highest%CF in the segments of leaf.The diversity index analyses of Shannon-Weiner,Simpson’s index,species richness and species evenness of diversity showed that leaf of N.Khasiana has the highest diversity than the other parts of the plant.So,with the help of the present finding,we conclude that the distribution of fungal endophytes and their%colonization frequencies vary within different tissues of the host plant and thus,this confirms tissue specificity nature of endophytic fungi. | Naseem F Kayang H | 2021 | Studies in Fungi2021，6，1： | 0 |
| 3 | Diversity of endophytic fungi associated with the medicinally important aromatic plant Gaultheria fragrantissima显示文摘A total of thirty three(33)endophytic fungi including sterile mycelia were isolated from the leaf,stem and roots of medicinally important aromatic plant Gaultheria fragrantissima.Majority of the fungi belonged to the phylum Ascomycota.The total percentage colonization frequency(%CF)of each endophytic fungal species was calculated of which Juxtiphoma eupyrena showed highest colonization frequency(20.14%)in the leaf whereas Globisporangium irregulare was found to have highest colonization frequency in the stem(14.58%)and in the roots,Trichoderma viride was observed to have the highest colonization frequency of 21.43%.Diversity of endophytic fungi in the roots was found to be higher as compared to the other plant tissues. | Sarma P Dkhar MS Kayang H Kumar M Dubey NK Raghuwanshi R | 2018 | Studies in Fungi2018，3，1： | 0 |
