The enigma of interspecific plasmodesmata: insight from parasitic plants
(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 ... -
A highly efficient protocol for transforming Cuscuta reflexa based on artificially induced infection sites
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-10)The parasitic plant genus <i>Cuscuta</i> is notoriously difficult to transform and to propagate or regenerate in vitro. With it being a substantial threat to many agroecosystems, techniques allowing functional analysis of gene products involved in host interaction and infection mechanisms are, however, in high demand. We set out to explore whether <i>Agrobacterium</i>‐mediated transformation of ... -
Selective mineral transport barriers at Cuscuta-host infection sites
(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 ...
