“…Colletotrichum is commonly known as foliar pathogens; for example, C. gloeosporioides is considered as a worldwide plant pathogen because it causes anthracnose to infect many plant species (Wang et al 2008). Additionally, to our knowledge, the infrequent genera Mucor and Neurospora were first reported endophytes in Huperzia, but they have been isolated from other host plants such as Solanum cernuum (Vieira et al 2012) and Acer ginnala (Qi et al 2009. The result supports the viewpoint that a few species are frequent colonizers, and yet the majority is rare inhabitants in plants (Liu et al 2009).…”

Endophytic fungi are an underexploited resource of natural products and have a capacity to produce diverse classes of plant-derived secondary metabolites. Here, we investigated the diversity of endophytic fungi from Huperzia serrata and the potential for discovering novel fungal natural products. One hundred and fifty-five endophytic fungi isolates obtained from H. serrata, belonging to four classes Dothideomycetes (47.3 %), Sordariomycetes (36.8 %), Eurotiomycetes (10.6 %) and an undefined class (5.3 %, Mucoraceae), were grouped into nine genera based on morphological and molecular identification. Colletotrichum, Cladosporium, Sordariomycetes and Guignardia were the dominant genera, whereas the remaining genera were infrequent groups. To our knowledge, the fungal genera Mucor and Neurospora were first reported in Huperzia plant. Among these endophytic fungi isolates, strain B14, belonging to Penicillium oxalicum, gave a gray precipitate with Dragendorff's reagent. A new pentapeptide was isolated from the culture of strain B14, and its chemical structure was elucidated on the basis of spectroscopic data from (1)H NMR, (13)C NMR and ESI-MS/MS. Taken together, H. serrata has a significant diversity of endophytic fungi that could be a rich resource for the discovery of new natural products.

“…The T-RFLP profiles did not reveal any dominating bands in any accessed organs at any site, except perhaps for Kitale roots, which, however, were colonized by a very species-poor endophytic fungal community. The majority of the detected genera are known to occur as endophytes: Cladosporium (Guo et al, 2000), Epicoccum (Jumpponen and Jones, 2009), Cryptococcus (Schweigkofler and Prillinger, 1999), Sporomiella (Suryanarayanan et al, 1998), Penicillium (Narisawa et al, 2002), Kabatiella (Butin, 1992), Lecythophora (de Errasti et al, 2010), Coniochatea (anamorph Lecythophora ) (Weber, 2002), Nigrospora (Soca-Chafre et al, 2011), Cordyceps (Rubini et al, 2005), Fimetariella (Martin-Garcia et al, 2012), Fusarium (Verma et al, 2011), Neurospora (Qi et al, 2009). Others have so far not been detected as endophytes: Gloetinia temulenta is a grass pathogen (Hardison, 1962); Pseudaleuria is a soil fungus (Xu et al, 2012); Zopfiella latipes is a marine fungus, but can colonize Phragmites (Poon and Hyde, 1998).…”

Antimicrobial drimane sesquiterpenes and their effect on endophyte communities in the medical tree Warburgia ugandensis

et al. 2014

Metabolite profiles (GC–−MS), drimane sesquiterpenes, sugars and sugar alcohols, were compared with bacterial and fungal endophyte communities (T-RFLP, DNA clones, qPCR) in leaves and roots of the pepper bark tree, Warburgia ugandensis (Canellaceae). Ten individuals each were assessed from two locations east and west of the Great Rift Valley, Kenya, Africa, which differed in humidity and vegetation, closed forest versus open savannah. Despite organ- and partially site-specific variation of drimane sesquiterpenes, no clear effects on bacterial and fungal endophyte communities could be detected. The former were dominated by gram-negative Gammaproteobacteria, Pseudomonadaceae and Enterobacteriaceae, as well as gram-positive Firmicutes; the fungal endophyte communities were more diverse but no specific groups dominated. Despite initial expectations, the endophyte community of the pepper bark tree did not differ from other trees that much.

Endophytes as potential pathogens of the baobab species Adansonia gregorii: a focus on the Botryosphaeriaceae

2011

Adansonia gregorii (baobab) is an iconic tree species occurring in the NW of Australia. Dying baobabs, A. digitata, have been reported from southern Africa and as A. gregorii is closely related to A. digitata, surveys were conducted to assess the health of the Australian baobab. The endophytic microflora of A. gregorii and surrounding tree species was sampled and the ability of these endophytes to cause disease in A. gregorii was determined. Endophytes were isolated from asymptomatic baobabs across 24 sites in the Kimberley region, north-west Australia (NW Australia). Material was also taken from surrounding native tree species at three sites. Material was also collected from asymptomatic and dying Adansonia species in the George Brown Darwin Botanic Gardens and from a dying baobab in a nursery in Broome. Endophytic fungi isolated from these samples were identified using morphological and molecular methods.Eleven botryosphaeriaceous species were identified along with 18 other nonbotryosphaeriaceous species; L. theobromae 1 was the most common species. The pathogenicity of the botryosphaeriaceous species to baobabs was determined by inoculating the taproot of seedlings and stems of young baobab trees. Lasiodiplodia theobromae was confirmed as a potentially significant pathogen of baobabs.2
