  • First report of Teratosphaeria gauchensis causing stem canker of Eucalyptus in Kenya 
    Machua, Joseph; Jimu, L.; Njuguna, J.; Wingfield, Michael J.; Mwenje, E.; Roux, Jolanda (Wiley, 2016-04)
    Teratosphaeria stem canker is an important disease of Eucalyptus species in many parts of the world where these trees are intensively propagated in plantations. Symptoms similar to those of Teratosphaeria stem canker ...
  • Fungal genomics challenges the dogma of name-based biosecurity 
    McTaggart, Alistair R.; Van der Nest, Magrieta Aletta; Steenkamp, Emma Theodora; Roux, Jolanda; Slippers, Bernard; Shuey, Louise S.; Wingfield, Michael J.; Drenth, Andre (Public Library of Science, 2016-05-05)
    Microorganisms have inadvertently been spread via the global movement and trade of their substrates, such as animals, plants, and soil. This intercontinental exchange in the current era of globalisation has given rise ...
  • Host jumps shaped the diversity of extant rust fungi (Pucciniales) 
    McTaggart, Alistair R.; Shivas, R.G.; Van der Nest, Magrieta Aletta; Roux, Jolanda; Wingfield, Brenda D.; Wingfield, Michael J. (Wiley, 2016-02)
    The aim of this study was to determine the evolutionary time line for rust fungi and date key speciation events using a molecular clock. Evidence is provided that supports a contemporary view for a recent origin of rust ...
  • New host range and distribution of Ceratocystis pirilliformis in South Africa 
    Lee, Dong Hyeon; Roux, Jolanda; Wingfield, Brenda D.; Barnes, Irene; Wingfield, Michael J. (Springer, 2016-11)
    Ceratocystis pirilliformis was first described from wounds on Eucalyptus trees in Australia and subsequently found as a common wound inhabitant on these trees in South Africa. During a recent disease survey carried out ...
  • Overlap of latent pathogens in the Botryosphaeriaceae on a native and agricultural host 
    Mehl, James William Montague; Slippers, Bernard; Roux, Jolanda; Wingfield, Michael J. (Elsevier, 2017-04)
    Some species of the Botryosphaeriaceae are capable of infecting a broad range of host plants. We studied the species diversity of Botryosphaeriaceae associated with marula (Sclerocarya birrea subsp. caffra, Anacardiaceae) ...
  • Rust (Puccinia psidii) recorded in Indonesia poses a threat to forests and forestry in South-East Asia 
    McTaggart, Alistair R.; Roux, Jolanda; Granados, Ginna Marcela; Gafur, Abdul; Tarrigan, Marthin; Santhakumar, P.; Wingfield, Michael J. (Springer, 2016-02)
    Over the past decade, Puccinia psidii, which causes rust on species of Myrtaceae, has spread rapidly to new areas and is now widespread. Quarantine has done little to prevent its movement through the Americas, the ...
  • A unique genotype of the rust pathogen, Puccinia psidii, on Myrtaceae in South Africa 
    Roux, Jolanda; Granados, Ginna Marcela; Shuey, Louise S.; Barnes, Irene; Wingfield, Michael J.; McTaggart, Alistair R. (Springer, 2016-12)
    The rust pathogen, Puccinia psidii, was first detected in South Africa in 2013 on a single non-native ornamental Myrtus communis tree. This prompted surveys of the country to determine its geographic distribution and ...
  • Uromycladium acaciae, the cause of a sudden, severe disease epidemic on Acacia mearnsii in South Africa 
    McTaggart, Alistair R.; Doungsa-ard, Chanintorn; Wingfield, Michael J.; Roux, Jolanda (Springer, 2015-11)
    A severe rust disease has caused extensive damage to plantation grown Acacia mearnsii trees in the KwaZulu- Natal Province of South Africa since 2013. The symptoms are characterized by leaf spots, petiole and rachis ...
