Parasitic plants, including the root holoparasites Orobanche spp., cause devastating damage to crops worldwide. Arabidopsis thaliana (L.) is widely used an amenable model for the study of plant biology, including plant-pathogen interactions. Bringing the two plants together in a controlled system will enable the study of the molecular and genetic basis involved in host-parasitic plant interacti...

Orobanche crenata (parasitic weed) is highly limiting factor for faba bean productions and the most serious agricultural economic importance pests in south wollo, eastern Ethiopia.

The seeds of parasitic plants of the genera Striga and Orobanche will only germinate after induction by a chemical signal exuded from the roots of their host. Up to now, several of these germination stimulants have been isolated and identified in the root exudates of a series of host plants of both Orobanche and Striga spp. In most cases, the compounds were shown to be isoprenoid and belong to ...

introduction: mycorrhizal symbiosis is one of the most popular and highest symbiotic relationship in plant kingdom. most plants (about 80% of vascular plant species) have at least one type of mycorrhiza. arbuscular mycorrhizal fungies are the most important endomycorhiza fungi that play an important role in agriculture. materials and methods: in order to evaluate the effect of arbuscular mycorr...

Parasitic angiosperms are a pest for many crops in the World. Broomrapes (Orobanche spp.) belong to this group of parasites and attach to the roots of the hosts in order to take water and nutrients from them. This causes a pernicious effect on the crops which can lead to a complete yield loss in some cases. No complete control measures are available to date, but breeding for resistance remains ...

Two parasitic and achlorophyllous species, Aeginetia indica and Orobanche minor belonging to the family Orobanchaceae, were surveyed for flavonoids. The flowers and aerial parts of A. indica were exracted with MeOH and the flavonoids were isolated by various chromatographical techniques. Two anthocyanins were obtained from the flowers together with other flavonoids, and characterized as cyanidi...

We report on the occurrence of Orobanche krylowii in the Alpet Shqiptare (Prokletije, Albanian Alps) mountain range in northern Albania (Balkan Peninsula). The species was previously known only from eastern-most Europe (Volga-Kama River in Russia), more than 2500 km away, and from adjacent Siberia and Central Asia. We used morphological evidence as well as nuclear ribosomal ITS sequences to sho...

Pea (Pisum sativum) is an important grain legume crop whose cultivation in the Mediterranean basin and West Asia is severely constrained by infection by the weedy root parasite Orobanche crenata (crenate broomrape). Pea is a false host of other species such as O. minor, O. foetida and Phelipanche aegyptiaca. In the present experiments, we demonstrate that seed germination of the Orobanche and P...

Crenate broomrape (Orobanche crenata) is a root parasitic weed that represents a major constraint for grain legume production in Mediterranean and West Asian countries. Medicago truncatula has emerged as an important model plant species for structural and functional genomics. The close phylogenic relationship of M. truncatula with crop legumes increases its value as a resource for understanding...
