    Zamora-Ballesteros, Cristina; Wingfield, Brenda D.; Wingfield, Michael J.; Martin-Garcia, Jorge; Diez, Julio J. (MDPI, 2021-01)
    Mycoviruses are known to be difficult to cure in fungi but their spontaneous loss occurs commonly. The unexpected disappearance of mycoviruses can be explained by diverse reasons, from methodological procedures to ...
  • Resistance sniffer : an online tool for prediction of drug resistance patterns of Mycobacterium tuberculosis isolates using next generation sequencing data 
    Muzondiwa, Dillon; Mutshembele, Awelani; Pierneef, Rian Ewald; Reva, Oleg N. (Elsevier, 2020-02)
    The effective control of multidrug resistant tuberculosis (MDR-TB) relies upon the timely diagnosis and correct treatment of all tuberculosis cases. Whole genome sequencing (WGS) has great potential as a method for ...
  • Resolving the phylogeny and population genetic structure of South African pollinating fig wasps 
    Erasmus, J.C. (Johannes Christoff) (University of Pretoria, 2011-06-16)
    A distinct pattern of obligate mutualism exists between fig tree hosts and their pollinating fig wasps. Normally one section or subsection of fig tree hosts is associated with one fig wasp genus. In general, each species ...
