Development of novel approaches to study Cuscuta campestris biology
Cuscuta campestris is an obligate parasitic plant that lacks expanded leaves and roots and requires a host to complete its lifecycle. Parasite-host connections occur via an haustorium, a unique organ that acts as a bridge for the exchange of water, nutrients, macromolecules like mRNA, microRNA, and …

Characterizing RNA translocation in the parasitic weed Cuscuta pentagona
The obligate stem parasite Cuscuta pentagona is able to take up host plant mRNA through a specialized organ known as the haustorium. Direct cell-to-cell symplastic connections between two different organisms are rare, and the translocation mechanisms and fate of these RNAs in the parasite is not …

Host use and foraging in the parasitic plant Cuscuta subinclusa.
… and growth. Stems of the parasitic plant Cuscuta subinclusa invest in resource acquisition (coil) relative to host quality in a way predicted by the marginal value theorem (MVT) in that: (1) stem coiling, the necessary antecedent and determinant of resource uptake, precedes exploitation of …

Plastid Genome Evolution in the Parasitic Genera Cuscuta (Convolvulaceae) and Krameria (Krameriaceae)
… freely, including the plastid genome. The genus Cuscuta is one such lineage. It contains c. 200 obligate branch parasite species, diverse in terms of the degree of their heterotrophy: some can conduct limited photosynthesis whilst others are entirely nonphotosynthetic. In chapters 2-4, I …

Population Genetics and Host Specificity of a Rare Parasitic Plant, Cuscuta harperi
<p><em>Cuscuta harperi</em> is a rare parasitic plant endemic to a small number of widely disjunct populations in Georgia and Alabama. It is a habitat-specialist, occurring on sandstone and granite outcrops within its limited range; it is also exhibits a high level of host specificity, parasitizing …

Molekulare Charakterisierung der Reaktion von Lycopersicon esculentum auf den phanerogamen Parasiten Cuscuta reflexa
… Interaktion von Lycopersicon esculentum und Cuscuta reflexa wird die Ausbildung von Haustorien, spezieller Organe, die der Nahrungsaufnahme durch den Parasiten dienen,bereits in einem sehr frühen Stadium der Infektion gehemmt. Um einen Einblick in die Regulationsmechanismen der …

Massive Exchange of mRNA between a Parasitic Plant and its Hosts
Cuscuta pentagona is an obligate parasitic plant that hinders production of crops throughout the world. Parasitic plants have unique morphological and physiological features, the most prominent being the haustorium, a specialized organ that functions to connect them with their host's vascular …

The use of reverse genetics to investigate plant-parasite interactions
… Desaturase gene in the holoparasitic plant Cuscuta campestris was also shown to hinder growth, branching and a reduce the production of tissue carotenoid biosynthesis. Taken together the results of this thesis offer new avenues for targeted treatment of globally relevant crop pests and lay …

Cross-Species Translocation of mRNA from Host Plants into the Parasitic Plant Dodder
Dodders (Cuscuta spp.) are parasitic plants that live by tapping into the vascular tissue of a host plant. Contents of the host phloem translocate readily into the parasite, and shared plasmodesmata have been documented between host cortical cells and dodder searching hyphae. Dodder is known to …

Exploring host-parasitic plant interactions by examining mechanisms of resistance and susceptibility
… (Egyptian broomrape) and the shoot parasite Cuscuta gronovii (swamp dodder), as well as investigations into Arabidopsis and tomato molecular responses to parasitism. These comparative studies reveal parasite-induced changes in hosts across diverse plant systems. The chapter II of the …
