Adaptations of Pseudoxylaria towards a comb-associated lifestyle in fungus-farming termite colonies Fricke, Janis; Schalk, Felix; Kreuzenbeck, Nina B.; Seibe, Elena; Hoffmann, Judith; Dittmann, Georg; Conlon, Benjamin H.; Guo, Huijuan; De Beer, Z. Wilhelm; Vassão, Daniel Giddings; Gleixne, Gerd; Poulsen, Michael; Beemelmanns, Christine (Springer, 2023-05)Characterizing ancient clades of fungal symbionts is necessary for understanding the evolutionary process underlying symbiosis development. In this study, we investigated a distinct subgeneric taxon of Xylaria (Xylariaceae), ...

Antifungal actinomycetes associated with the pine bark beetle, Orthotomicus erosus, in South Africa Human, Z.R. (Zander Rainier); Slippers, Bernard; De Beer, Z. Wilhelm; Wingfield, Michael J.; Venter, S.N. (Stephanus Nicolaas) (Academy of Science of South Africa, 2017-01)Actinomycete bacteria are often associated with insects that have a mutualistic association with fungi. These bacteria are believed to be important to this insect–fungus association as they produce antibiotics that exclude ...

Human, Z.R. (Zander Rainier); Moon, Kyuho; Bae, Munhyung; De Beer, Z. Wilhelm; Cha, Sangwon; Wingfield, Michael J.; Slippers, Bernard; Oh, Dong-Chan; Venter, S.N. (Stephanus Nicolaas) (Frontiers Research Foundation, 2016-11-02)Common saprophytic fungi are seldom present in Protea infructescences, which is strange given the abundance of mainly dead plant tissue in this moist protected environment. We hypothesized that the absence of common ...

Osorio, J. Alexander; Crous, Casparus J.; Wingfield, Michael J.; De Beer, Z. Wilhelm; Roux, Jolanda (Oxford University Press, 2017-05)Mangroves are critically important components of coastal ecosystems. However, their survival is globally threatened, mostly due to impacts resulting from human activities. Reports of mangrove deaths associated with pathogens ...

(Oxford University Press, 2022-08)Studies addressing the economic impacts of invasive alien species are biased towards ex-post assessments of the costs and benefits of control options, but ex-ante assessments are also required to deal with potentially ...

Linnakoski, Riikka; De Beer, Z. Wilhelm; Niemela, Pekka; Wingfield, Michael J. (MDPI Publishing, 2012-02-15)Bark beetles (Coleoptera, Scolytinae) have a widespread association with fungi, especially with ophiostomatoid fungi (Ascomycota) that cause blue staining of wood, and in some cases, serious tree diseases. In Fennoscandia, ...

Hulcr, Jiri; Barnes, Irene; De Beer, Z. Wilhelm; Duong, Tuan A.; Gazis, Romina; Johnson, Andrew J.; Jusino, Michelle A.; Kasson, Matthew T.; Li, You; Lynch, Shannon; Mayers, Chase; Musvuugwa, Tendai; Roets, Francois; Seltmann, Katja C.; Six, Diana; Vanderpool, Dan; Villari, Caterina (Springer, 2020-06-03)One of the main threats to forests in the Anthropocene are novel or altered interactions among trees, insects and fungi. To critically assess the contemporary research on bark beetles, their associated fungi, and their ...

Nel, Wilma Janine; Duong, Tuan A.; De Beer, Z. Wilhelm; Wingfield, Michael J. (Wiley, 2019-06)Black root rot caused by the pathogen Thielaviopsis basicola has been known since the mid 1800s. The disease is important on many agricultural and ornamental plant species and has been found in at least 31 countries. Since ...

Wilken, Pieter Markus; Steenkamp, Emma Theodora; Hall, Tracy A.; De Beer, Z. Wilhelm; Wingfield, Michael J.; Wingfield, Brenda D. (Elsevier, 2012)In heterothallic Ascomycota, two opposite but distinct mating types control all sexual processes. Using mating crosses, mating types were assigned to ten isolates of the heterothallic fungal species Ophiostoma quercus. ...

De Beer, Z. Wilhelm; Marincowitz, Seonju; Duong, Tuan A.; Wingfield, Michael J. (Pensoft Publishers, 2017-10)Recent reclassification of the Ceratocystidaceae (Microascales) based on multi-gene phylogenetic inference has shown that the oak wilt fungus Ceratocystis fagacearum does not reside in any of the four genera in which it ...

Paciura, Dina; Zhou, Xudong; De Beer, Z. Wilhelm; Jacobs, Karin; Ye, H. (Springer, 2010-01)Ophiostomatoid fungi on trees are typically bark beetle associates that cause sapstain in timber and some are pathogens. Very little is known regarding the ophiostomatoid fungi associated with bark beetles in China and the ...
-
Duong, Tuan A.; De Beer, Z. Wilhelm; Wingfield, Brenda D.; Wingfield, Michael J. (Elsevier, 2013-06)Leptographium procerum and the closely related species Leptographium profanum, are ascomycetes associated with root-infesting beetles on pines and hardwood trees, respectively. Both species occur in North America where ...

Um, Soohyun; Guo, Huijuan; Thiengmag, Sirinthra; Benndorf, Rene; Murphy, Robert; Rischer, Maja; Braga, Daniel; Poulsen, Michael; De Beer, Z. Wilhelm; Lackner, Gerald; Beemelmanns, Christine (American Chemical Society, 2021-07)Morphotype switches frequently occur in Actinobacteria and are often associated with disparate natural product production. Here, we report on differences in the secondary metabolomes of two morphotypes of a Streptomyces ...

Murphy, Robert; Benndorf, Rene; De Beer, Z. Wilhelm; Vollmers, John; Kaster, Anne-Kristin; Beemelmanns, Christine; Poulsen, Michael (American Society for Microbiology, 2021-03)Actinobacteria, one of the largest bacterial phyla, are ubiquitous in many of Earth’s ecosystems and often act as defensive symbionts with animal hosts. Members of the phylum have repeatedly been isolated from basidiomyc ...

Marincowitz, Seonju; Duong, Tuan A.; De Beer, Z. Wilhelm; Wingfield, Michael J. (Elsevier, 2015-07)Little is known about the biology of the monotypic genus Cornuvesica (Microascales), apart from that isolates are notoriously difficult to culture on artificial media. A recent collection of material resembling this genus ...
