Orobanche and Phelipanche, commonly known as broomrape, are dicotyledonous holoparasitic flowering plants that cause heavy economic losses in a wide variety of plant species. Egyptian broomrape (Phelipanche aegyptiaca Pomel.) parasitizes more than 30 food and ornamental crops, including tomato,

In this study, the isolation and characterization of a phytochrome A (PHYA) homologous cDNA (OmPHYA) in the non-photosynthetic holoparasitic plant Orobanche minor are described. The present findings provide the first report of the presence of a PHYA homolog in the holoparasite. This study found that

Broomrape (Orobanche aegyptiaca Pers.), an important obligate root parasitic weed in India, has a wide host range including several members of the Solanaceae, Leguminaceae, and Brassicaceae families, among others. Orobanche plants produce thousands of tiny seeds (250 × 300 μm), which can remain

Broomrape (Orobanche aegyptiaca L.), one of the most important parasitic weeds in Iran, is a root parasitic plant that can attack several crops such as tobacco, sunflower, tomato and etc. Several methods were used for Orobanche control, however these methods are inefficient and very costly.

The kalanchoe (Kalanchoe blossfeldiana) is an important ornamental species belonging to Crassulaceae. This plant is grown in commercial greenhouses. A survey revealed infections of broomrape, Orobanche aegyptiaca Pers. (syn. Phelipanche aegyptiaca Walp.), on kalanchoe plants in the province of

Broomrapes (Orobanche spp.) are obligate parasites that infect roots of dicotyledoneous plants. Orobanche spp. are particularly important in southern and eastern Europe, the Middle East, and north Africa. O. crenata causes severe damage to legume crops, O. cumana threatens sunflower, O. ramosa

We have determined the nucleotide sequence for the Rubisco large subunit from four holoparasitic species of Orobanche. Intact open reading frames are present in two species (O. corymbosa and O. fasciculata), whereas the remaining species (O. cernua and O. ramosa) have rbcL pseudogenes. Sequences for

Orobanche spp. are angiosperms that live parasitically on the roots of other plants, and are capable of significantly reducing the yield and quality of their crop hosts. We have demonstrated that parasitization by Orobanche induces expression of hmg2, a defense-related isogene of

Broomrapes (Orobanche spp.) are parasitic plants, whose growth and development fully depend on the nutritional connection established between the parasite and the roots of the respective host plant. Phytohormones are known to play a role in establishing the specific Orobanche-host plant interaction.

Branched broomrape is a holoparasitic weed present in some areas of central and southern Chile (33°S to 38°S), which is often found parasitizing tomato and tobacco crops. During an extensive survey conducted in different tomato-growing areas during the summer of 2010, branched broomrape plants with

Orobanche ramosa L. is arguably the most insidious of the major broomrapes, achlorophyllous root parasites of various row crops (4). It has a broad host range and is the most widely spread of any agronomically important broomrape. In the United States, California, Kentucky, and Texas have persistent

OBJECTIVE Broomrapes (Orobanche spp.) are holoparasitic weeds that cause devastating losses in many economically important crops. The molecular mechanisms that control early stages of host infection in Orobanche are poorly understood, partly due to the lack of experimentally tractable in vitro

Branched broomrape (Orobanche ramosa L.) is a chlorophyll-lacking, root parasitic plant that infects many crops and wild species (2). Plants are densely hairy with minute, glandular hairs, particularly on flowers and upper stems. Stems are erect, often branched just above the ground, and brown to

Demands for plant growth regulators (PGRs; chemicals that control plant growth) are increasing globally, especially in developing countries. Both positive and negative PGRs are widely used to enhance crop production and to suppress unwanted shoot growth, respectively. Strigolactones (SLs) are
