Host 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 کاملIncreased Virulence in Sunflower Broomrape (Orobanche cumana Wallr.) Populations from Southern Spain Is Associated with Greater Genetic Diversity
Orobanche cumana Wallr. (sunflower broomrape) is a holoparasitic weed that infects roots of sunflower in large areas of Europe and Asia. Two distant O. cumana gene pools have been identified in Spain, one in Cuenca province in the Center and another one in the Guadalquivir Valley in the South. Race F has been hypothesized to have arisen by separate mutational events in both gene pools. In the G...
متن کاملPre-haustorial resistance to broomrape (Orobanche cumana) in sunflower (Helianthus annuus): cytochemical studies.
Sunflower broomrape (Orobanche cumana Wallr.) is a root holoparasitic angiosperm considered as one of the major constraints for sunflower production in Mediterranean areas. Breeding for resistance is regarded as the most effective, feasible, and environmentally friendly solution to control this parasite. However, the existing sources of genetic resistance are defeated by the continuous emergenc...
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 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...
