  • Ceratocystis wilt on Eucalyptus : first record from South Africa 
    Roux, Jolanda; Wingfield, Michael J.; Fourie, Arista; Noeth, K.; Barnes, Irene (NISC (Pty) Ltd and Informa UK Limited (trading as Taylor and Francis Group), 2020)
    Wilt and death of an E. grandis × E. urophylla variety was recently observed in the Zululand region of KwaZulu-Natal, South Africa. Symptoms on the dying trees included a streaking pattern of discolouration in the sapwood ...

(International Mycological Association, 2019-09-13)
    Draft genomes of the fungal species Fusarium xylarioides, Teratosphaeria gauchensis and T. zuluensis are presented. In addition an annotation of the genome of Ceratocystis fimbriata is presented. Overall these genomes ...
  • Global population genomics of the forest pathogen Dothistroma septosporum reveal chromosome duplications in high dothistromin-producing strains 
    Bradshaw, Rosie E.; Sim, Andre D.; Chettri, Pranav; Dupont, Pierre‐Yves; Guo, Yanan; Hunziker, Lukas; McDougal, Rebecca L.; Van der Nest, Ariska; Fourie, Arista; Wheeler, David; Cox, Murray P.; Barnes, Irene (British Society for Plant Pathology and John Wiley & Sons Ltd, 2019-06)
    Dothistroma needle blight is one of the most devastating pine tree diseases worldwide. New and emerging epidemics have been frequent over the last 25 years, particularly in the Northern Hemisphere, where they are in ...
  • IMA Genome-F 11 : draft genome sequences of Fusarium xylarioides, Teratosphaeria gauchensis and T. zuluensis and genome annotation for Ceratocystis fimbriata

  • Inheritance of phenotypic traits in the progeny of a Ceratocystis interspecific cross 
    Fourie, Arista; Wingfield, Michael J.; Wingfield, Brenda D.; Van der Nest, Magrieta Aletta; Loots, Mattheus Theodor; Barnes, Irene (Elsevier, 2018-07)
    Ceratocystis fimbriata is a fungal plant pathogen that causes black rot on Ipomoea batatas. Based on inoculation studies on numerous tree species, the pathogen is known to be host specific. The closely related species, ...
  • Mating genes in Calonectria and evidence for a heterothallic ancestral state 
    Li, JieQiong; Wingfield, Brenda D.; Wingfield, Michael J.; Barnes, Irene; Fourie, Arista; Crous, Pedro W.; Chen, S.F. (Naturalis Biodiversity Center and Centraalbureau voor Schimmelcultures, 2020-03-17)
    The genus Calonectria includes many important plant pathogens with a wide global distribution. In order to better understand the reproductive biology of these fungi, we characterised the structure of the mating type ...
  • Molecular markers delimit cryptic species in Ceratocystis sensu stricto 
    Fourie, Arista; Wingfield, Michael J.; Wingfield, Brenda D.; Barnes, Irene (Springer, 2015)
    Ceratocystis sensu stricto is a genus of closely related fungi that are mostly plant pathogens. Morphological variation between species in this genus is limited and species delineation is strongly reliant on phylogenetic ...
  • New Ceratocystis species associated with rapid death of Metrosideros polymorpha in Hawai'i 
    Barnes, Irene; Fourie, Arista; Wingfield, Michael J.; Harrington, T.C.; McNew, D.L.; Sugiyama, L.S.; Luiz, B.C.; Heller, W.P.; Keith, L.M. (Naturalis Biodiversity Center, 2018-03-27)
    The native ˋōhiˋa lehua (Metrosideros polymorpha) has cultural, biological and ecological significance to Hawai`i, but it is seriously threatened by a disease commonly referred to as rapid ˋōhiˋa death (ROD). Preliminary ...
  • A possible centre of diversity in South East Asia for the tree pathogen, Ceratocystis manginecans 
    Fourie, Arista; Wingfield, Michael J.; Wingfield, Brenda D.; Thu, Pham Q.; Barnes, Irene (Elsevier, 2016-07)
    The fungal pathogen, Ceratocystis manginecans, has caused serious canker and wilt disease on Mangifera indica (mango), on legume tree species in Oman and Pakistan and on Acacia spp. in Indonesia. A Ceratocystis species, ...
