Reduced Germination of Orobanche cumana Seeds in the Presence of Arbuscular Mycorrhizal Fungi or Their Exudates
Broomrapes (Orobanche and Phelipanche spp) are parasitic plants responsible for important crop losses, and efficient procedures to control these pests are scarce. Biological control is one of the possible strategies to tackle these pests. Arbuscular Mycorrhizal (AM) fungi are widespread soil microorganisms that live symbiotically with the roots of most plant species, and they have already been ...
متن کاملHost recognition of Orobanche cumana, the broomrape of cultivated sunflower
Background and aims: Most of the economically relevant parasitic weeds of the Orobanchaceae have a more or less broad host spectrum within the plant family they are adapted to. The hostreleased compounds inducing their germination were identified as so-called strigolactones and represent four-ring terpenoids derived from the carotenoid metabolism. O. cumana, a fast emerging problem of sunflow...
متن کاملThe Eff icacy of Resistance Inducing Agents for the Control of Sunflower Broomrape (Orobanche cumana
The resistance inducing agent 1, 2, 3-Benzothiadiazole-7-carbothioic acid S-methyl ester (BTH) has been demonstrated in triggering defence reactions in crop plants against bacterial, fungal and viral pathogens but also against parasitic weeds of the genus Orobanche. In this study, pot experiments were conducted under greenhouse conditions to evaluate the efficacy of different concentrations of ...
متن کاملDifferential 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 کاملSunflower Resistance to Broomrape (Orobanche cumana) Is Controlled by Specific QTLs for Different Parasitism Stages
Orobanche cumana (sunflower broomrape) is an obligatory and non-photosynthetic root parasitic plant that specifically infects the sunflower. It is located in Europe and in Asia, where it can cause yield losses of over 80%. More aggressive races have evolved, mainly around the Black Sea, and broomrape can rapidly spread to new areas. Breeding for resistance seems to be the most efficient and sus...
