The timing of germination is the most crucial event that obligated parasitic plants face along their life cycle (Figure 2C). In addition, the biological similarity between host and parasite characterizing broomrape-crop interactions is higher than in other plant pathosystems, which complicates the development of selective methods to control broomrape, without harmful effect in the crop from which it is feeding (Eizenberg et al., 2006; Hearne, 2009; Yoder and Scholes, 2010; Prez-Vich et al., 2013).

Ecological of weed seed size and persistence in the soil under different tilling systems: implications for weed management. Global invasive potential of 10 parasitic witchweeds and related Orobanchaceae. Weed Res. Soil management affects the success of broomrape seeds in becoming established on the host and then the longevity of broomrape seed bank. Several toxins have been identified with inhibitory activity on broomrape parasitism by interfering with broomrape germination and radicle elongation (Vurro et al., 2009; Fernndez-Aparicio et al., 2013; Cimmino et al., 2014). Though, the effect of L-methionine on internal crop resistance was not studied and requires further investigation. doi: 10.1094/PD-89-0023, Singh, A., and Singh, M. (1993).

Structure and function of natural and synthetic signaling molecules in parasitic weed germination. An important piece of this research is identifying the best time to apply an herbicide to slow down the broomrape with a minimum of damage to the tomatoes. Plant Growth Regul. The relationship between the organic nitrogen status of Egyptian broomrape and one of its hosts, carrot, was studied by comparing amino acid profiles of leaf and root tissues of nonparasitized and broomrape-parasitized carrot plants and by analyzing amino acid profiles of broomrape at different growth stages. This paper reviews relevant facts about the biology of broomrape weeds, the key mechanisms they employ to attack crops and the control methods already developed or in development that directly target those mechanisms. This work was cofunded by the European Union and INRA, in the framework of the Marie-Curie FP7 COFUND People Program, through the award of an AgreenSkills fellowship (under grant agreement n PCOFUND-GA-2010-267196) to MF-A with additional support by the INRA Division Sant des Plantes et Environnement., Abbasher, A.

However, it is a long-term strategy due to the long viability of seed bank (Rubiales et al., 2009b), which requires at least a nine-course rotation in order to prevent broomrape seed bank increases (Grenz et al., 2005). Lack of knowledge in the molecular regulation of the host-parasite interaction during crop invasion has impeded the development of varieties carrying transgenes with capacity to inhibit broomrape penetration.

A better understanding of the biochemistry of host recognition in broomrape will facilitate the generation of control strategies targeting the haustorium development. The majority of strategies aimed to manage autotrophic weeds do not necessarily work for broomrapes and those that provide a degree of success for broomrape need to be optimized for each broomrape-crop species combination, local environmental conditions and broomrape population. Fernndez-Aparicio M, Masi M, Cimmino A, Evidente A. Mediterr. Food Chem. Several factors contribute to the fact that broomrape weeds remain an uncontrolled agricultural problem. Broomrape high fecundity, with thousands of seeds released per broomrape plant (Figures 2A,B), multiplies the chances of the next generation to encounter a host and achieve successful parasitism (Parker and Riches, 1993).

Babiker, A. G. T., Hamdoun, A. M., Rudwan, A., Mansi, N. G., and Faki, H. H. (1987). In non-parasitic plants, physiological dormancy can be relieved through stratification but in the case of broomrape weeds, two consecutive processes are required to release dormancy: an environment-dependent first step of warm stratification called the conditioning phase, and a host-dependent second step of chemodetection.

J. 112 297308. 33, 787793. Delayed sowing date is a traditional method that can show high degree of success on inhibiting parasitism if implemented correctly (Lpez-Granados and Garca-Torres, 1996; Rubiales et al., 2003a; Prez-de-Luque et al., 2004; Grenz et al., 2005). Those interactions promote the broomrape seed bank remains dormant inhibiting the initiation of broomrape parasitism, and therefore its rates of seed bank replenishment. For each broomrape-crop association, broomrape germination potential is defined by the combination of both, the stimulatory capability of crop root exudates and the sensitivity of parasitic receptors to recognize specific forms of germination-inducing factors (Fernndez-Aparicio et al., 2008a, 2009b, 2011). Among the reviewed strategies are those aimed (1) to reduce broomrape seed bank viability, such as fumigation, herbigation, solarization and use of broomrape-specific pathogens; (2) diversion strategies to reduce the broomrape ability to timely detect the host such as those based on promotion of suicidal germination, on introduction of allelochemical interference, or on down-regulating host exudation of germination-inducing factors; (3) strategies to inhibit the capacity of the broomrape seedling to penetrate the crop and connect with the vascular system, such as biotic or abiotic inhibition of broomrape radicle growth and crop resistance to broomrape penetration either natural, genetically engineered or elicited by biotic- or abiotic-resistance-inducing agents; and (4) strategies acting once broomrape seedling has bridged its vascular system with that of the host, aimed to impede or to endure the parasitic sink such as those based on the delivery of herbicides via haustoria, use of resistant or tolerant varieties and implementation of cultural practices improving crop competitiveness. doi: 10.1007/s00425-011-1568-8, Yoneyama, K., Xie, X., Kusumoto, D., Sekimoto, H., Sugimoto, Y., Takeuchi, Y., et al.

R. (1971). Being deprived of the initiation of autotrophic mode of life, the growth of broomrape seedling toward the host is only sustained by water absorption and remobilization of reserve nutrients from the seed perisperm and endosperm (Joel, 2000; Joel et al., 2012). Sci. As a consequence the crop is protected from broomrape invasion (Joel and Portnoy, 1998; Westwood et al., 1998; Hamamouch et al., 2005; Aly et al., 2006). Effective broomrape control should target the underground mechanisms of crop parasitism in order to meet both the short-term productivity expectations of the farmer and reduction of soil bank in the long run (Figure 1). 62, 1048510492.

The predictability of establishment on perennial hosts is high and therefore wild broomrape species feeding off perennial plants have narrow host ranges. Crops with target-site herbicide resistance for Orobanche and Striga control. Besides arginine and aspartate, other major forms of amino acids translocate from the host phloem but they are rapidly utilized by broomrape. In addition, inhibitors of ABA catabolism inhibit the germination-triggering effect of host-derived strigolactones. Federal government websites often end in .gov or .mil. The transfer of nutrients from host to broomrape is performed through a continuous vascular system at the host-parasite interface. The inductor potential of root exudates from a given species varies with the broomrape considered. Lpez-Granados, F., and Garca-Torres, L. (1999). (Berner et al., 1999; Ahonsi et al., 2003), a close relative of broomrapes, however, broomrape germination is not responsive to ethylene (Joel, 2000).

However, instability of this compound, particularly at pH > 7.5, and lack of optimal formulations rendered this technique not applicable (Saghir, 1986; Babiker et al., 1987, 1988). Use of other soil sterilants such as metham sodium, dazomet, and 1,3-dichloropropene have shown different degrees of efficacy but their high cost, complex application and negative environmental effects have prevented their widespread use by farmers (Foy et al., 1989; Goldwasser et al., 1995; Hershenhorn et al., 2009) or conducted to the withdrawal of authorization, at least in some countries.
