• Nitrogen-fixing bacteria and Oxalis – evidence for a vertically inherited bacterial symbiosis 

      Jooste, Michelle; Roets, Francois; Midgley, Guy F.; Oberlander, Kenneth C.; Dreyer, Leanne L. (BMC (part of Springer Nature), 2019-10-23)
      Background: Plant-endophyte symbioses often revolve around nitrogen metabolism, and involve varying degrees of intimacy. Although evidence for vertical inheritance of nitrogen-fixing endophytic bacteria is increasing, it ...
    • Oxalis seeds from the Cape Flora have a spectrum of germination strategies 

      Jooste, Michelle; Midgley, Guy F.; Oberlander, Kenneth C.; Dreyer, Leanne L. (Botanical Society of America, 2019)
      PREMISE OF THE STUDY: Seed germination strategy has profound ecological and evolutionary consequences, with transitions between germination strategies receiving renewed recent attention. Oxalis from the Cape Flora, South ...
    • The phylogenetic significance of leaf anatomical traits of southern African oxalis 

      Jooste, Michelle; Dreyer, Leanne L.; Oberlander, Kenneth C. (BioMed Central, 2016-10)
      Background: The southern African Oxalis radiation is extremely morphologically variable. Despite recent progress in the phylogenetics of the genus, there are few morphological synapomorphies supporting DNA-based clades. ...
