Differential induction of Orobanche seed germination by Arabidopsis thaliana.
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...
متن کاملPlanteose as a storage carbohydrate required for early stage of germination of Orobanche minor and its metabolism as a possible target for selective control
Root parasitic weeds in Orobanchaceae cause serious damage to worldwide agriculture. Germination of the parasites requires host-derived germination stimulants, such as strigolactones, as indicators of host roots within reach of the parasite's radicles. This unique germination process was focused on to identify metabolic pathways required for germination, and to design a selective control strate...
متن کاملRecognition of root exudates by seeds of broomrape (Orobanche and Phelipanche) species.
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...
متن کاملSHORT COMMUNICATION The role of strigolactones in host specificity of Orobanche and Phelipanche seed germination
Strigolactones are apocarotenoids regulating shoot branching. They are also known to be exuded by plant roots at very low concentrations, stimulating hyphal branching of arbuscular mycorrhizal fungi and germination of root parasitic weed seeds. We show that strigolactones play a major role in host specificity of Orobanche and Phelipanche (the broomrapes) seed germination. This observation confi...
متن کاملAromatic A-ring analogues of orobanchol, new germination stimulants for seeds of parasitic weeds.
Strigolactones are signaling compounds in plants of increasing importance. In this paper the focus is on their activity as germinating agents for seeds of parasitic weeds. The syntheses of aromatic A-ring analogues of the germination stimulant orobanchol have been described. Starting substrate is the ABC unit of the stimulant GR24. Oxidation at the C-4 position gives a 4-oxo derivative which on...
