BACKGROUND AND AIMS The long co-existence of broomrapes and their hosts within the same environment has culminated in a strong adaptation and effective parasitism. As a first step of specialization in the parasitic process, seed receptors of parasitic plant species vary in their ability to recognize compounds released by their hosts. This work aims to investigate potential patterns for the rece...

Orobanche ramosa (broomrape) is a widespread parasitic weed of many Solanaceouse crop species, such as tobacco or tomato, and attaches to many other species, including ornamentals and weeds. It is mainly distributed in the Mediterranean area, central Europe, northern Africa, and the Middle East (Press and Graves, 1995).Many fungi were isolated from diseased Orobanche plants, and some of them pr...

Faba bean (Vicia faba) production in Mediterranean and Near East agriculture is severely constrained by broomrape infection. The most widely distributed broomrape species affecting faba bean is Orobanche crenata, although O. foetida and Phelipanche aegyptiaca are of local importance. Only moderately resistant cultivars are available to farmers. Rizotrons studies allowed the dissection of resist...

Crenate broomrape (Orobanche crenata Forsk.) is a root parasitic weed severely threatening the cultivation of pea (Pisum sativum L.) in Mediterranean agricultural settings. We recently characterized a pea line highly resistant to O. crenata, named ROR12. Analysis of root exudates indicated that ROR12 resistance is possibly due to lower exudation of strigolactones, carotenoid-derived compounds a...

Canavar otları (Orobanche spp.) dikotiledon bitkilerde önemli düzeyde ürün kayıplarına neden olan tam parazit bitkilerdir. Türkiye’nin de yer aldığı Akdeniz iklimine sahip ülkelerde domates, tütün, patates, havuç, maydanoz, ayçiçeği ve mercimek, gibi bazı kültür bitkilerinin üretimi canavar spp./Phelipanche tarafından tehdit edilmektedir. Bu çalışmada Hatay ilinin farklı ilçelerinde otu tür(ler...

Root parasitic weeds are a major limiting production factor in a number of crops, and control is difficult. Genetic resistance and chemical control lead the fight, but without unequivocal success. Models that help to describe and even predict the evolution of parasitism underground are a valuable tool for herbicide applications, and even could help in breeding programs. Legumes are heavily affe...

Strigolactones are germination stimulants for seeds of the root parasitic weeds, Striga and Orobanche spp. The imino analog of GR24 showed moderate germination stimulating activity against the seeds of S. hermonthica. The seed germination stimulating activity of some phenyliminoacetates and phenyliminoacetonitriles was also examined. The degree of activity of the phenyliminoacetate was less tha...
