  • Diversity of gall-forming rusts (Uromycladium, Pucciniales) on Acacia in Australia 
    Doungsa-ard, C.; McTaggart, Alistair R.; Geering, A.D.W.; Shivas, R.G. (Naturalis Biodiversity Center, 2018-05-16)
    Uromycladium tepperianum has been reported on over 100 species of Acacia, as well as on the closely related plant genera, Falcataria, Racosperma and Paraserianthes. Previous studies have indicated that U. tepperianum may ...
  • The genus Ravenelia (Pucciniales) in South Africa 
    Ebinghaus, Malte; Wingfield, Michael J.; Begerow, D.; Maier, W. (Springer, 2020-04)
    The genus Ravenelia represents the third largest genus of rust fungi and parasitizes a great number of leguminous shrubs and trees, mainly in the subtropics and tropics.Molecular phylogenetic analyses of this genus using ...
  • 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 ...
  • The pandemic biotype of Austropuccinia psidii discovered in South America 
    Granados, Ginna Marcela; McTaggart, Alistair R.; Barnes, Irene; Rodas, Carlos A.; Roux, Jolanda; Wingfield, Michael J. (Springer, 2017-05)
    The rust fungus Austropuccinia psidii was recently reported from ornamental Corymbia citriodora and plantations of Eucalyptus in Colombia. It is unknown whether the genotypic diversity of the pathogen in Colombia reflects ...
  • The pandemic strain of Austropuccinia psidii causes myrtle rust in New Zealand and Singapore 
    Du Plessis, Erika Margarete; Granados, Ginna Marcela; Barnes, Irene; Ho, W.H.; Alexander, B.J.R.; Roux, Jolanda; McTaggart, Alistair R. (Springer, 2019-05)
    The myrtle rust pathogen, Austropuccinia psidii, was recently detected in New Zealand and Singapore. We used microsatellite markers to identify the strain of A. psidii that caused these incursions. Our results show that ...
  • 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 ...
  • Sexual reproduction in populations of Austropuccinia psidii 
    McTaggart, Alistair R.; Du Plessis, Esna; Roux, Jolanda; Barnes, Irene; Fraser, Stuart; Granados, Ginna Marcela; Ho, Wellcome W.H.; Shuey, Louise S.; Drenth, Andre (Springer, 2020-02)
    Austropuccinia psidii is a rust fungus that has expanded its known geographic distribution and host range on Myrtaceae. Invasions by rust fungi are often caused by asexual urediniospores that give rise to populations with ...
  • 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 ...
