“…Rapid and precise identification of species is the vital and critical first step in the fields of conservation, sustainable use of biodiversity [1], ecology [2], pathogen prevention and control [3], quarantine control of exotic species [4], forensic investigations [5], and human health [6,7]. Using purely morphological methods to identify fungal species poses some problems.…”

To determine a suitable DNA barcode for the genus Neonectria, the internal transcribed spacer rDNA, β-tubulin, EF-1α, and RPB2 genes were selected as candidate markers. A total of 205 sequences from 19 species of the genus were analyzed. Intraand inter-specific divergences and the ease of nucleotide sequence acquisition were treated as criteria to evaluate the feasibility of a DNA barcode. Our results indicated that any single gene among the candidate markers failed to serve as a successful barcode, while the combination of the partial EF-1α and RPB2 genes recognized all species tested. We tentatively propose the combined partial EF-1α and RPB2 genes as a DNA barcode for the genus. During this study, two cryptic species were discovered, based on the combined data of morphology and DNA barcode information. We described and named these two new species N. ditissimopsis and N. microconidia. intra-specific variation, inter-specific variation, morphology, DNA barcode, sequence analysis Citation:Zhao P, Luo J, Zhuang W Y, et al.

“…Human activity and movement of plant materials is also commonly implicated in the dispersal of fungi and has resulted in the spread of devastating pathogens between countries and continents (Brown & Hovmøller, 2002;Wingfield et al, 2001;2010). Examples of migration at an intercontinental or even global scale are available for lichen-forming (Buschbom, 2007), saprobic (Moncalvo & Buchanan, 2008), ectomycorrhizal (Moyersoen et al, 2003) and marine fungi (Pang et al, 2013).…”

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 Protea species through arthropod-mediated dispersal. Using microsatellite markers, this study considered the process whereby a Protea-associated ophiostomatoid fungus, Knoxdaviesia proteae, recolonizes a burnt area. The genetic diversity, composition and structure of fungal populations from young P. repens plants in a recently burnt area were compared to populations from the adjacent, unburnt Protea population. The only difference between K. proteae populations from the two areas was found in the number of private alleles, which was significantly higher in the unburnt population. The population structure, although weak, indicated that most K. proteae 1 individuals from recently burnt areas originated from the unburnt population. However, individuals from unsampled source populations were also detected. This, together with the lack of isolation-by-distance across the landscape, suggested that long-distance dispersal is important for K. proteae to recolonize burnt areas. Similarly, the high level of gene flow and low differentiation observed between two distantly separated K. proteae populations also supported the existence of long-distance dispersal. The genetic cohesiveness of populations over long distances and the genetic diversity within populations could be attributed to frequent multiple fungal migration events mediated primarily by arthropods but, potentially, also by birds.

“…By 2006, some 496,000 hectares of productive commercial forestry land in South Africa had been planted to non-native Eucalyptus (Forestry South Africa 2006). This resource is seriously threatened by alien invasive pests and pathogens (Wingfield et al 2008;Wingfield et al 2001). Accidental introductions and impacts of insect pests of trees appear to be increasing due to global trade and travel (Brockerhoff et al 2006;Wingfield et al 2008).…”

DNA bar-coding reveals source and patterns of Thaumastocoris peregrinus invasions in South Africa and South America

et al. 2009

Thaumastocoris peregrinus is a recently introduced invertebrate pest of non-native Eucalyptus plantations in the Southern Hemisphere. It was first reported from South Africa in 2003 and in Argentina in 2005. Since then, populations have grown explosively and it has attained an almost ubiquitous distribution over several regions in South Africa on 26 Eucalyptus species. Here we address three key questions regarding this invasion, namely whether only one species has been introduced, whether there were single or multiple introductions into South
