    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 ...
  • 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. ...
