“…Recently, and as previously mentioned, populations overcoming race F resistance, named as races G and H, have also been identified in several countries and a continuous search for sources of resistance for these new races has been carried out (Kaya et al, 2004Pacureanu-Joita et al, 2009;Antonova et al, 2013). The non-existence of differential lines for new broomrape races makes defining broomrape races on the global level more difficult (Škorić et al, 2010).…”

“…Turkey is another country where infections of sunflowers by O. cumana endanger the crop production in every growing season. Race F is widely distributed in Trakya region (Kaya et al, 2004), which accounts for more than half of the total area of sunflowers in the country. Also, race G has been identified in several locations of this same region .…”

Broomrape, caused by Orobanche cumana, has affected sunflowers since the early 20 th century in Eastern Europe. Currently, it limits sunflower oil production in Southern and Eastern Europe and in some areas of Asia, causing around 50% seed losses when susceptible hybrids are grown. Covered in this review are aspects such as: biological processes that are common to Orobanche spp. and/or particular to O. cumana in sunflower, genetic resistance and its mechanisms, races of the parasite identified in different countries throughout the time and their increasing virulence, and breeding for resistance to some herbicides as a novel control option. The main purpose is to present an updated and, as far as possible, complete picture of the way both the parasitic weed and its host crop have evolved in time, and how they co-exist in the current agriculture. Additionally, we propose a system for determining the races of the parasite that can be internationally adopted from now. In the context of minimal harmful effects on the environment, changing patterns of land use in farming systems, and global environment changes, the final goal of this work is to provide all those interested in parasites from field crops and their integrated management compiled information on the sunflower -O. cumana system as a case study.Additional key words: genes of resistance; Helianthus annuus L.; broomrape; parasite races; virulence.

“…Resistance to this new race was found in germplasm of both cultivated and wild sunflowers (Sukno et al, 1999;Fernández-Martínez et al, 2000;Rodríguez-Ojeda et al, 2001), but a more virulent race G was identified soon after cultivars resistant to race F entered the market (Molinero-Ruiz and MeleroVara, 2005). Virulent races overcoming the resistance gene Or 5 have also been identified in Romania (Pâcureanu et al, 2004), Russia (Goncharov et al, 2004), Israel (Eizenberg et al, 2004), Bulgaria (Shindrova, 2006) and Turkey (Kaya et al, 2004). In the last country, the new races seem to be more virulent than those present in other countries.…”

Sunflower broomrape (Orobanche cumana Wallr) continues to be one of the most important constraints in sunflower production in Spain. In the last ten years, genetic resistance has been the predominant control strategy against O. cumana. However, the introduction of new resistance genes has been frequently followed by the occurrence of new virulent races overcoming their resistance. In this report, a combined control strategy against O. cumana is discussed, including: a) the use of IMI sunflower cultivars to control winter and early spring weeds and sunflower broomrape; b) the combination of vertical and horizontal resistance mechanisms in the same genotype, supported by molecular markers in order to develop a more durable resistance; c) the study of the variability and racial composition of Spanish sunflower broomrape populations using classical and molecular approaches with the objective to learn about population dynamics in this parasitic weed. The combination of such strategies is expected to contribute to improved sunflower performance in areas infested by broomrape in the Mediterranean area.

Transcriptional activity of four defence-related genes (NPR1, PAL, defensin and PR5) in seven sunflower lines À resistant (MS-2161A), tolerant (MS-2039A) and susceptible (MS-2098A, MS-2091A, MS-2077A, MS-2067A and MS-1589A), infected with three broomrape populations (Tulcea, Romania; Soroca and Anenii Noi, Republic of Moldova), was studied in advanced stages of infection (90 days after sowing). Obtained results revealed that resistant genotypes are characterized through higher stability in transcriptional activity of the studied genes. Thus, resistance could be associated with ability rapidly to maintain and recover a normal level of metabolism under more intensive stress factors. Also, it was established that expression of PR5 and defensin genes was altered and revealed considerable deviations in this phase of adaptation, while NPR1 and PAL mostly showed values at the level of the control group, which allows assuming that these genes, in the moment of sample collection and analysis, had normalized transcriptional activity, probably being involved in early responses.
