Machingambia, Netsai M.; Roux, Jolanda; Dreyer, Leanne Laurette; Roets, Francois (Elsevier, 2014-05)Bark and ambrosia beetles are ecologically and economically important phloeophagous insects that often have complex symbiotic relationships with fungi and mites. These systems are greatly understudied in Africa. In the ...

Roets, Francois; Theron, Natalie; Wingfield, Michael J.; Dreyer, Leanne Laurette (Elsevier, 2012-01)Estimations of global fungal diversity are hampered by a limited understanding of the forces that dictate host exclusivity in saprobic microfungi. To consider this problem for Gondwanamyces and Ophiostoma found in the ...

Machingambi, N.M.; Dreyer, Leanne Laurette; Oberlander, Kenneth C.; Roets, Francois; Roux, Jolanda (Wiley, 2015-10)Numerous dead and dying individuals of the Western Cape endemic tree Virgilia oroboides (Fabaceae) were recently observed within a South African national botanical garden. Root-rot fungi and fungi symbiotic with bark ...

Ngubane, Nombuso P.; Dreyer, L.L. (Leanne Laurette); Slippers, Bernard; Kemler, Martin; Begerow, Dominik; Witfeld, Frederick; Brachmann, Andreas; Roets, Francois (Elsevier, 2023-10)Host identity and location help shape fungal endophyte assemblages in plants. Hosts act as uptake filters from the environment and closely related hosts in the same location may harbour similar assemblages. We assessed the ...

Aylward, Janneke; Dreyer, Leanne Laurette; Steenkamp, Emma Theodora; Wingfield, Michael J.; Roets, Francois (Springer, 2014-05)Knoxdaviesia proteae is one of the first native ophiostomatoid fungi discovered in South Africa, where it consistently occurs in the infructescences of the iconic Cape Biome plant, Protea repens. Although numerous ...

Musvuugwa, Tendai; Dreyer, Leanne Laurette; Roets, Francois (Elsevier, 2016-08)The Ophiostomatales contain pathogens that threaten forests world-wide. Global trade increases encounters with new hosts, with potential devastating consequences. We assessed the danger posed by the movement of Ophiostomatales ...

Aylward, Janneke; Steenkamp, Emma Theodora; Dreyer, Leanne Laurette; Roets, Francois; Wingfield, Brenda D.; Wingfield, Michael J. (BioMed Central, 2016-02-29)Two closely related ophiostomatoid fungi, Knoxdaviesia capensis and K. proteae, inhabit the fruiting structures of certain Protea species indigenous to southern Africa. Although K. capensis occurs in several Protea hosts, ...

Ngubane, Nombuso P.; Dreyer, Leanne L.; Slippers, Bernard; Kemler, Martin; Witfeld, Frederick; Begerow, Dominik; Brachmann, Andreas; Roets, Francois (Springer, 2023-12)CONTEXT : Land use change can significantly affect plant-fungal interactions. OBJECTIVES : We assessed how fungal endophytes within African wild olive (Olea europaea subsp. cuspidata) twigs are influenced by different ...

Aylward, Janneke; Dreyer, Leanne Laurette; Steenkamp, Emma Theodora; Wingfield, Michael J.; Roets, Francois (Elsevier, 2015-04)The Fynbos Biome in the Core Cape Subregion of South Africa is prone to recurrent fires that can clear vast areas of vegetation. Between periods of fire, ophiostomatoid fungi colonize the fruiting structures of serotinous ...

Roets, Francois; Crous, Pedro W.; Wingfield, Michael J.; Dreyer, Leanne Laurette (Entomological Society of America, 2009)Ophiostomatoid fungi are well known as economically important pathogens and agents of timber degradation. A unique assemblage of these arthropod-associated organisms including species of Gondwanamyces G. J. Marais and M. ...

Roets, Francois; Wingfield, Michael J.; Wingfield, Brenda D.; Dreyer, Leanne Laurette (Elsevier, 2011)Entomochoric spore dispersal is well-documented for most ophiostomatoid fungal genera, most of which are associated with bark or ambrosia beetles. Gondwanamyces spp. are unusual members of this group that were first ...

Musvuugwa, Tendai; De Beer, Z. Wilhelm; Duong, Tuan A.; Dreyer, Leanne Laurette; Oberlander, Kenneth C.; Roets, Francois (Springer, 2015-10)Olea capensis and Rapanea melanophloeos are important canopy trees in South African Afromontane forests. Dying or recently dead individuals of these trees are often infested by Scolytinae and Platypodinae (Curculionidae) ...

Roets, Francois; Wingfield, Brenda D.; De Beer, Z. Wilhelm; Wingfield, Michael J.; Dreyer, Leanne Laurette (Nationaal Herbarium Nederland & Centraalbureau voor Schimmelcultures, 2010-06)The genus Ophiostoma (Ophiostomatales) has a global distribution and species are best known for their association with bark beetles (Curculionidae: Scolytinae) on conifers. An unusual assemblage of these fungi is closely ...

Musvuugwa, Tendai; De Beer, Z. Wilhelm; Duong, Tuan A.; Dreyer, Leanne Laurette; Oberlander, Kenneth C.; Roets, Francois (Springer, 2016-06)Rapanea melanophloeos, an important canopy tree in Afromontane forests, is commonly utilised for medicinal bark harvesting. Wounds created from these activities provide entrance for many fungi, including arthropod-associated ...
