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 …

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 …

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 …

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 …

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 …

Radial growth patterns of jack pine in relation to climate, moisture availability, and dwarf mistletoe infection in the Boreal Plains Ecozone of Saskatchewan, Canada
… americanum) (DM) is a host specific, parasitic plant of jack pine (Pinus banksiana) that affects resource allocation, water use, and growth. Despite being one of the most damaging pests to jack pine in the Canadian boreal forest, it has not been well studied in relation to the …

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 …

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 …

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 …
