  • Wingfield, Brenda D. (AOSIS Open Journals, 2014)
    I have now been awarded virtually every NRF (National Research Foundation) rating reasonably available. Many years ago at the start of my academic life I received a 'Y' label; I have recently been awarded an 'A' rating. ...
  • Duran, Alvaro; Gryzenhout, Marieka; Drenth, Andre; Slippers, Bernard; Ahumada, Rodrigo; Wingfield, Brenda D.; Wingfield, Michael J. (Elsevier, 2010-09)
    Phytophthora pinifolia is the causal agent of the recently discovered needle disease of Pinus radiata in Chile, referred to as “Daño Foliar del Pino” (DFP). The genetic structure of the pathogen population is unknown, which ...
  • Sayari, Mohammad; Van der Nest, Magrieta Aletta; Steenkamp, Emma Theodora; Adegeye, O.O.; Marincowitz, Seonju; Wingfield, Brenda D. (Elsevier, 2019-09)
    Functional association between genomic loci and specific biological traits remains lacking in many fungi, including the African tree pathogen Ceratocystis albifundus. This is mainly because of the absence of suitable ...
  • Simpson, M.C. (Melissa Claire); Wilken, Pieter Markus; Coetzee, Martin Petrus Albertus; Wingfield, Michael J.; Wingfield, Brenda D. (Elsevier, 2013-07)
    Ceratocystis fimbriata sensu lato represents a complex of cryptic and commonly plant pathogenic species that are morphologically similar. Species in this complex have been described using morphological characteristics, ...
  • Phasha, Mmatshepho Malekgale; Wingfield, Brenda D.; Coetzee, Martin Petrus Albertus; Santana, Quentin C.; Fourie, Gerda; Steenkamp, Emma Theodora (Genetics Society of America, 2017-11)
    Removal of introns from transcribed RNA represents a crucial step during the production of mRNA in eukaryotes. Available whole-genome sequences and expressed sequence tags (ESTs) have increased our knowledge of this ...
  • Linnakoski, Riikka; Sutela, Suvi; Coetzee, Martin Petrus Albertus; Duong, Tuan A.; Pavlov, Igor N.; Litovka, Yulia A.; Hantula, Jarkko; Wingfeld, Brenda D.; Vainio, Eeva J. (Nature Research, 2021-04)
    Species of Armillaria are distributed globally and include some of the most important pathogens of forest and ornamental trees. Some of them form large long-living clones that are considered as one of the largest organisms ...
  • Coetzee, Martin Petrus Albertus; Wingfield, Brenda D.; Wingfield, Michael J. (MDPI, 2018-10-24)
    This review considers current knowledge surrounding species boundaries of the Armillaria root-rot pathogens and their distribution. In addition, a phylogenetic tree using translation elongation factor subunit 1-alpha ...
  • Van Zuydam, Natalie R.; Paciura, Dina; Jacobs, Karin; Wingfield, Michael J.; Coetzee, Martin Petrus Albertus; Wingfield, Brenda D. (The Mycological Society of America, 2010-11)
    Leptographium species provide an ideal model to test the applications of a PCR microcoding system for differentiating species of other genera of ascomycetes. Leptographium species are closely related and share similar gross ...
  • Wadke, Namita; Kandasamy, Dineshkumar; Vogel, Heiko; Lah, Ljerka; Wingfield, Brenda D.; Paetz, Christian; Wright, Louwrance Peter; Gershenzon, Jonathan; Hammerbacher, Almuth (American Society of Plant Biologists, 2016-06)
    Norway spruce (Picea abies) is periodically attacked by the bark beetle Ips typographus and its fungal associate, Endoconidiophora polonica, whose infection is thought to be required for successful beetle attack. Norway ...
  • 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. ...
  • Wingfield, Brenda D. (AOSIS Open Journals, 2016-01)
    Science and research consume a substantial – some might say the greater part – of my life. It is an all-consuming passion that many fail to understand. Professionally, I divide my time between managing a substantial ...
  • Lombard, Lorenzo; Rodas Pelaez, C.A. (Carlos Alberto); Crous, Pedro W.; Wingfield, Brenda D.; Wingfield, Michael J. (Nationaal Herbarium Nederland & Centraalbureau voor Schimmelcultures, 2009)
    Calonectria (Ca.) species and their Cylindrocladium (Cy.) anamorphs are well-known pathogens of forest nursery plants in subtropical and tropical areas of the world. An investigation of the mortality of rooted Pinus cuttings ...
  • Lombard, Lorenzo; Zhou, Xudong; Crous, Pedro W.; Wingfield, Brenda D.; Wingfield, Michael J. (Nationaal Herbarium Nederland & Centraalbureau voor Schimmelcultures, 2010-01)
    Decline in the productivity of Eucalyptus hybrid cutting production in the Guangdong Province of China is linked to cutting rot associated with several Calonectria spp. The aim of this study was to identify these fungi ...
  • Wingfield, Brenda D. (Academy of Science of South Africa, 2011)
    Student throughput rates have become a much debated topic, not only in the South African academic environment but in many parts of the world. Of particular concern are Master's and PhD degrees: how many years should students ...
  • Martin, Simon H.; Wingfield, Brenda D.; Wingfield, Michael J.; Steenkamp, Emma Theodora (Oxford University Press, 2011)
    The reproductive genes of fungi, like those of many other organisms, are thought to diversify rapidly. This phenomenon could be associated with the formation of reproductive barriers and speciation. Ascomycetes produce ...
  • Simpson, M.C. (Melissa Claire); Coetzee, Martin Petrus Albertus; Van der Nest, Magrieta Aletta; Wingfield, Michael J.; Wingfield, Brenda D. (Elsevier, 2018-12)
    Mating is central to many fungal life cycles and is controlled by genes at the mating-type (MAT) locus. These genes determine whether the fungus will be self-sterile (heterothallic) or self-fertile (homothallic). Species ...
  • Van Wyk, Marelize; Wingfield, Brenda D.; Mohali, S.; Wingfield, Michael J. (Kunming University of Science and Technology, P.R. China, 2009-01)
