    • The enigma of interspecific plasmodesmata: insight from parasitic plants 

      Fischer, Karsten; Lachner, Lena Anna-Maria; Olsen, Stian; Mulisch, Maria; Krause, Kirsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-01)
      Parasitic plants live in intimate physical connection with other plants serving as their hosts. These host plants provide the inorganic and organic compounds that the parasites need for their propagation. The uptake of the macromolecular compounds happens through symplasmic connections in the form of plasmodesmata. In contrast to regular plasmodesmata, which connect genetically identical cells of ...

    • Footprints of parasitism in the genome of the parasitic flowering plant Cuscuta campestris 

      Vogel, Alexander; Schwacke, Rainer; Denton, Alisandra; Usadel, Björn; Hollmann, Julien; Fischer, Karsten; Bolger, Anthony; Schmidt, Maximilian; Bolger, Marie; Grundlach, Heidrun; Mayer, Klaus F.X.; Weiss-Schneeweiss, Hanna; Temsch, Eva M.; Krause, Kirsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-28)
      A parasitic lifestyle, where plants procure some or all of their nutrients from other living plants, has evolved independently in many dicotyledonous plant families and is a major threat for agriculture globally. Nevertheless, no genome sequence of a parasitic plant has been reported to date. Here we describe the genome sequence of the parasitic field dodder, Cuscuta campestris. The genome contains ...

    • Selective mineral transport barriers at Cuscuta-host infection sites 

      Förste, Frank; Mantouvalou, Ioanna; Kanngiesser, Birgit; Stosnach, Hagen; Lachner, Lena Anna-Maria; Fischer, Karsten; Krause, Kirsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-11)
      The uptake of inorganic nutrients by rootless parasitic plants, which depend on host connections for all nutrient supplies, is largely uncharted. Using X‐ray fluorescence spectroscopy (XRF), we analyzed the element composition of macro‐ and micronutrients at infection sites of the parasitic angiosperm <i>Cuscuta reflexa</i> growing on hosts of the genus <i>Pelargonium</i>. Imaging methods combining ...
