  • The healthy human blood microbiome : fact or fiction? 
    Castillo, Diego J.; Rifkin, Riaan F.; Cowan, Don A.; Potgieter, Marnie (Frontiers Media, 2019-05-08)
    The blood that flows perpetually through our veins and arteries performs numerous functions essential to our survival. Besides distributing oxygen, this vast circulatory system facilitates nutrient transport, deters ...
  • LEA proteins and the evolution of the WHy domain 
    Mertens, Jasmin; Aliyu, Habibu; Cowan, Don A. (American Society for Microbiology, 2018-05)
    The LEA family is composed of a diverse collection of multi-domain and multi-functional proteins, found in all three Domains of the Tree of Life, but particularly common in plants. Most members of the family are known to ...
  • Microbial nitrogen cycling in antarctic soils 
    Ortiz, Maximiliano; Bosch, Jason; Coclet, Clement; Johnson, Jenny; Lebre, Pedro H.; Salawu-Rotimi, Adeola; Vikram, Surendra; Makhalanyane, Thulani P.; Cowan, Don A. (MDPI, 2020-09)
    The Antarctic continent is widely considered to be one of the most hostile biological habitats on Earth. Despite extreme environmental conditions, the ice-free areas of the continent, which constitute some 0.44% of the ...
  • Pathogen infection influences a distinct microbial community composition in sorghum RILs 
    Masenya, K.; Thompson, G.D.; Tekere, M.; Makhalanyane, Thulani P.; Pierneef, Rian Ewald; Rees, D.J.G. (Springer, 2021-06)
    AIMS: The rhizosphere microbiome substantially affects plant health, yet comparatively little is known regarding the foliar community dynamics. Here, we examine the relationship between the microbiota and their response to ...
  • Phages actively challenge niche communities in Antarctic soils 
    Bezuidt, Keoagile Ignatius Oliver; Lebre, Pedro H.; Pierneef, Rian Ewald; Leon-Sobrino, Carlos; Adriaenssens, Evelien M.; Cowan, Don A.; Van de Peer, Yves; Makhalanyane, Thulani P. (American Society for Microbiology, 2020-05-05)
    By modulating the structure, diversity, and trophic outputs of microbial communities, phages play crucial roles in many biomes. In oligotrophic polar deserts, the effects of katabatic winds, constrained nutrients, and ...
  • Prokaryotic species are sui generis evolutionary units 
    Palmer, Marike; Venter, S.N. (Stephanus Nicolaas); Coetzee, Martin Petrus Albertus; Steenkamp, Emma Theodora (Elsevier, 2019-03)
    Many gene flow barriers associated with genetic isolation during eukaryotic species divergence, are lacking in prokaryotes. In these organisms the processes associated with horizontal gene transfer (HGT) may provide both ...
  • A reservoir of ‘historical’ antibiotic resistance genes in remote pristine Antarctic soils 
    Van Goethem, Marc W.; Pierneef, Rian Ewald; Bezuidt, Keoagile Ignatius Oliver; Van de Peer, Yves; Cowan, Don A.; Makhalanyane, Thulani P. (BioMed Central, 2018-02-23)
    BACKGROUND : Soil bacteria naturally produce antibiotics as a competitive mechanism, with a concomitant evolution, and exchange by horizontal gene transfer, of a range of antibiotic resistance mechanisms. Surveys of ...
  • Selection of marker genes for genetic barcoding of microorganisms and binning of metagenomic reads by Barcoder software tools 
    Rotimi, A.M. (Adeola); Pierneef, Rian Ewald; Reva, Oleg N. (BioMed Central, 2018-08-30)
    BACKGROUND : Metagenomic approaches have revealed the complexity of environmental microbiomes with the advancement in whole genome sequencing displaying a significant level of genetic heterogeneity on the species level. ...
