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 …

Exploring the genetic basis of germination specificity in the parasitic plants Orobanche cernua and O. cumana
… gene family, and suggests that within parasitic Orobanchaceae the KAI2 genes have undergone duplication and specialization. The "diverged" clade of these genes, termed KAI2d, has been shown to bind SL germination stimulants in model system assays, but the precise role for KAI2d in regulating …

Egyptian Broomrape (Orobanche aegyptiaca Pers.) and Small Broomrape (Orobanche minor Sm.) Parasitism of Red Clover (Trifolium pratense L.) in Vitro
… of the distinct characteristics of the family Orobanchaceae is the lack of chlorophyll, and hence inability to synthesize their own food. Broomrapes subsist on the roots of the host plant from which they derive the carbon, water, and nutrients needed for further growth. Parasitism as such leads …

Bridging the physiology and ecology of hemiparasitic plants
… and ecology of the Castillejinae tribe in the Orobanchaceae, a species-rich yet largely understudied group of annual and perennial genera. In several greenhouse experiments, I assessed the resource flow between host and hemiparasite and investigated whether the pattern of resource gain varied …

Impacts of hemiparasitic plants on the vegetation and biogeochemical cycling in two contrasting semi-natural grassland types
Hemiparasitic plants from the family Orobanchaceae play a key role in the conservation of species-rich semi-natural grasslands. They can alter plant community composition and diversity by both parasitism and litter effects. The drainage of resources by the hemiparasite suppresses preferred host …
