Entangled Relationships Illustrated Through Parasitic Plants
… based on interacting relationships between plants. My images focus on parasitic plants, as a metaphor for restrictive and binding aspects of human relationships. Several aspects of my work include psychological influences, my observations of the natural world, my artistic process and my …

Molecular perspective of protein-ligand selectivity in host and parasitic plants
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2024-12-01

Deciphering the chemistry of host-parasitic plants interactions using the UHPLC-q-TOF-MS and chemometrics
… extensively used in ethnomedicine globally, the parasitic nature of these plants can impact their secondary metabolite composition and thereby, influence their medicinal properties. The main objective of this study was to contrast the metabolome of Viscum combreticola Engl. (African mistletoe) …

Exploring the genetic basis of germination specificity in the parasitic plants Orobanche cernua and O. cumana
Seeds of the root parasitic plants of the genus Orobanche germinate specifically in response to host-derived germination signals, which enables parasites to detect and attack preferred hosts. The best characterized class of germination stimulants is the strigolactones (SLs), although some species …

Exploring host-parasitic plant interactions by examining mechanisms of resistance and susceptibility
Parasitic plants extract water and nutrients from host plants by using specialized structures called haustoria. These interactions can cause 100% crop losses, yet growers lack control options that are effective and affordable. Host crops with resistance to parasitism would be an ideal solution to …

Bridging the physiology and ecology of hemiparasitic plants
… based on photosynthesis is a defining feature of plants. However, some flowering plant lineages have adopted a heterotrophic lifestyle based on parasitism, either reducing or completely abandoning their ability to photosynthesize. Approximately 1-2% of all angiosperms directly parasitize other …

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 …

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 …

Plasticity of Primary Metabolism in Parasitic Orobanchaceae
Parasitic weeds of the family Orobanchaceae attach to the roots of host plants via haustoria capable of drawing nutrients from host vascular tissue. Species in this family span the spectrum of host nutrient dependency, allowing comparisons that provide insight into parasite adaptation. A key aspect …

Characterization of Host Plant Defense Responses to Parasitization by <I>Orobanche aegyptiaca</I>
<I>Orobanche</I> (spp.) are parasitic plants that attack the roots of many important crops. <I>O. aegyptiaca</I> penetrates the host root (aided by digestive enzymes) and forms connections to the host vascular tissue, from which it will withdraw all of its water and nutrient requirements. In order …

Host use and foraging in the parasitic plant Cuscuta subinclusa.
… survivorship 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 …

Composition, spatial abundance, co-occurrence and host preference of mistletoes in the Central highland savanna of Namibia
Aerial parasitic plants, commonly called mistletoes, are a polyphyletic group of organisms with a common evolutionary ancestor. This study was aimed at determining composition, spatial abundance within hosts, co-occurrence and host preference of mistletoes in the central highland savannas. The …

Investigations on the host-parasite interface of a mycoparasite system /
The cell wall composition of Choanephora cucur - bitarum and the host-parasite interface, after infection with Piptocephalis virginiana , were examined in detail. The cell walls of C_. cucurbitarum were determined to be composed of chitin (17%), chitosan (28.4%), neutral sugars (7.2%),uronic acid …

Ecology and Molecular Phylogenetics of <i>Hydnora</i> (Hydnoraceae) in Southern Africa
<p>The Hydnoraceae are a clade of root holoparasitic angiosperms that contain two small genera, <em>Hydnora</em> and <em>Prosopanche</em>. This study, focused on <em>Hydnora</em>, presents novel data regarding the pollination biology, germination ecology, parasite-host nutritional relationships, …

Thresholds for sustainable regeneration in urban restoration plantings in Hamilton City, New Zealand
… may no longer have viable populations. Forbs and parasitic plants, highly shade tolerant (i.e. late successional) species and those with biotic pollinators were under represented in the seed supply and understorey indicating some limitation for regeneration or colonisation in young urban forests. …
