    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 ...
  • Ceratocystidaceae exhibit high levels of recombination at the mating-type (MAT) locus 
    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 ...
  • Ceratocystis fimbriatomima, a new species in the C. fimbriata sensu lato complex isolated from Eucalyptus trees in Venezuela 
    Van Wyk, Marelize; Wingfield, Brenda D.; Mohali, S.; Wingfield, Michael J. (Kunming University of Science and Technology, P.R. China, 2009-01)
    Species of Ceratocystis represent a group of important plant pathogens as well as saprobes that occur, primarily on woody substrates. The number of species in Ceratocystis has increased substantially in recent years, ...
