N2 - Abstract: Sunflower broomrape (Orobanche cumana Wallr.) is an obligate parasitic plant specifically affecting sunflower and capable of causing substantial damage to its yield. In this relation, the production of broomrape-resistant cultivars of sunflower is an important agricultural challenge. Sunflower breeding for resistance to broomrape started way back in the beginning of the 20th century. In this field, due credit should be given to Soviet selectionists. However, production of new resistant cultivars of sunflower was accompanied by the emergence of novel virulent races of broomrape, which prevailed over resistance genes. For a number of sunflower loci responsible for resistance to broomrape, genetic mapping was performed but putative candidate genes were determined and possible molecular mechanism of their operation was described only for some of them. Not long ago, transcriptome data were obtained for broomrape-resistant and -susceptible cultivars of sunflower, which makes it possible to approach the understanding of molecular principles of resistance development. This review deals with the molecular and genetic mechanisms of sunflower resistance to broomrape revealed on the basis of mapping loci associated with resistance and identification of putative candidate genes, as well as on the basis of transcriptomic data.
