    Biodiversity and economic losses resulting from invasive plant pests and pathogens are increasing globally. For these impacts and threats to be managed effectively, appropriate methods of surveillance, detection and ...
  • Botanical gardens provide valuable baseline Phytophthora diversity data 
    Hulbert, J.M. (Joey); Paap, Trudy; Burgess, Treena I.; Roets, Francois; Wingfield, Michael J. (Elsevier, 2019-12)
    Phytophthora species are important plant pathogens especially due to their ability to invade and change ecosystems. However, information regarding their diversity and distribution is not available in many parts of the ...
  • Both mating types in the heterothallic fungus Ophiostoma quercus contain MAT1-1 and MAT1-2 genes 
    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. ...
  • Botryosphaeria dothidea : a latent pathogen of global importance to woody plant health 
    Marsberg, Angelica; Kemler, Martin; Jami, Fahimeh; Nagel, Jan Hendrik; Postma-Smidt, Alisa; Naidoo, Sanushka; Wingfield, Michael J.; Crous, Pedro W.; Spatafora, Joseph; Hesse, Cedar N.; Robbertse, Barbara; Slippers, Bernard (Wiley, 2017-05)
    Botryosphaeria dothidea is the type species of Botryosphaeria (Botryosphaeriaceae, Botryosphaeriales). Fungi residing in this order are amongst the most widespread and important canker and dieback pathogens of trees ...
  • The Botryosphaeriaceae : genera and species known from culture 
    Phillips, A.J.L.; Alves, A.; Abdollahzadeh, J.; Slippers, Bernard; Wingfield, Michael J.; Grienewald, J.Z.; Crous, Pedro W. (Cbs Publications, 2013-09-30)
    In this paper we give an account of the genera and species in the Botryosphaeriaceae. We consider morphological characters alone as inadequate to define genera or identify species, given the confusion it has repeatedly ...
  • Botryosphaeriaceae associated with Acacia heterophylla (La Réunion) and Acacia koa (Hawaii) 
    Jami, Fahimeh; Marincowitz, Seonju; Slippers, Bernard; Crous, Pedro W.; Le Roux, Johannes J.; Richardson, David M.; Wingfield, Michael J. (Elsevier, 2019-11)
    Acacia koa and A. heterophylla are commonly occurring native trees on the Hawaiian Islands and La Réunion, respectively. A recent phylogenetic study suggested that A. heterophylla renders A. koa paraphyletic, and that the ...
