Broomrape seeds are less capable to recognize crop roots colonized by arbuscular mycorrhizal fungi, Rhizobium leguminosarum or Azospirillum brasilense due to change in the composition of the root exudates in colonized plants (Dadon et al., 2004; Mabrouk et al., 2007a; Fernndez-Aparicio et al., 2009c, 2010b; Louarn et al., 2012).

How do nitrogen and phosphorus deficiencies affect strigolactone production and exudation? The use of those amino acids as pesticide is classified by the United States Environmental Protection Agency as innocuous to public and environment health (USEPA, 2004). Assessment of pathogenicity or damages toward non-target plants has to be carefully assessed in order to avoid environmental risks. Haustorium 54, 34. Plant Sci. 20, 8184. (2002). The second possibility to increase rotation efficacy for broomrape control is to include catch crops, which are crops that also induce high broomrape germination but they are not resistant to it.

It is well-established in autotrophic plants that abscisic acid (ABA) acts as a positive regulator of induction of seed dormancy and its maintenance and gibberelins (GAs) antagonizes with ABA, promoting dormancy release and subsequent germination (Finch-Savage and Leubner-Metzger, 2006). Several classes of germination stimulants have been identified in root exudates such as strigolactones (Xie et al., 2010), peagol and peagoldione (Evidente et al., 2009), peapolyphenols AC (Evidente et al., 2010), soyasapogenol B, trans-22-dehydrocampesterol (Evidente et al., 2011), dehydrocostus lactone (Joel et al., 2011), or isothyocyanates (Auger et al., 2012). High osmotic potential in roots and drop in amino acid levels in the phloem has been reported in tolerant varieties of faba bean in response to broomrape parasitism. consultancy for, shared ownership in or any close relationship with, at any time over the preceding 36 months, any organisation whose interests may be affected by the publication of the response.

The capacity of P. orobanchia to reduce broomrape populations is limited by cultural practices and antagonists (Klein and Kroschel, 2002; Aly, 2007). Flavonoids promote haustoria formation in the root parasite Triphysaria versicolor. Once ground has been infested, crop options for the field are extremely limited for a long period of time. Because parasitic weeds require host encoded molecules to stimulate the initiation of parasitism both at the level of seed germination and haustorium initiation, breeding for low-inducers genotypes of those processes are obvious targets for resistance (Yoder and Scholes, 2010). 11, 435442. doi: 10.1051/agro:2001167.

Benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH) acts as a functional analog of SA and activates defense responses in susceptible hosts leading to lignification of the endodermis and a consequent inhibition to up to 98% broomrape parasitism (Gonsior et al., 2004; Prez-de-Luque et al., 2004; Kusumoto et al., 2007). In this regard, France is doing valuable work through the Technical Center for Oilseed Crops and Industrial Hemp, Terresinovia, where a nationwide survey of infested fields is actualized online on real time by the farmers with new cases emerging every year and recently toward new regions such as the French Centre region1 Several studies suggest that large areas of new territory are at risk of invasion by broomrape (Mohamed et al., 2006; Grenz and Sauerborn, 2007), and in fact, invasions in completely new regions are already emerging in countries such as Spain, UK, France, Algeria, Ethiopia, Egypt, Sudan (Reda, 2006; Babiker et al., 2007; Babiker, 2008; Rubiales et al., 2008; Abu-Irmaileh and Labrada, 2009; Parker, 2014). Pest Manag. Comparative transcriptome analyses reveal core parasitism genes and suggest gene duplication and repurposing as sources of structural novelty. (1996). During the grafting between host and parasite, broomrape assumes the role of a root, orientating vascular tissues from the host shoot into itself (Bar-Nun et al., 2008). These connections are probably developed from simultaneous differentiation of adjacent host and parasite cells to xylem elements (Drr, 1997). Biol. -. (2009).

Systemic acquired resistance in crop protection: from nature to chemical approach. 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). doi: 10.1080/09583157.2015.1018813.

Veronesi, C., Bonnin, E., Benharrat, H., Fer, A., and Thalouarn, P. (2005). 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). In order to achieve such synchrony they evolved mechanisms that release seed from dormancy triggering germination upon detection of specific molecules contained in host root exudates (Vaucher, 1823).

(2009). Based on those conditions, methionine has the potential to be used as broomrape herbicide but it needs to be confirmed and its application adjusted to real field conditions. Although broomrape pre-vascular connections benefits from host nutrients, the growth of broomrape in its way toward vascular cylinder is mainly sustained by consumption of seed reserves (Aber et al., 1983; Joel and Losner-Goshen, 1994; Joel, 2000). Sauerborn, J. If this effect is confirmed, L-methionine use to elicit resistance to broomrape in susceptible crops could be a straightforward strategy either by direct applications of this amino acid in the soil as explained in Section Control Strategies Targeting Host Penetration or delivered by overproducing and excreting microorganisms as explained in Section Strategies to Control Underground Broomrapes Acting after Establishment.. (1999). J. Phytopathol. 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). Figure 1. 10.1016/j.plaphy.2008.10.004 8600 Rockville Pike The amino acid approach to control weeds is inspired on the concept of frenching disease where amino acid end-product inhibits the activity of a controlling enzyme in the amino acid biosynthesis pathway (Vurro et al., 2006, 2009; Sands and Pilgeram, 2009). After host adhesion to host root surface the haustorium develops its invasive function of penetrating the host root (Figure 2E). Seed dormancy and the control of germination. In addition it promotes the development of a layer of papillae at the radicle apex in the absence of host contact, morphology that resembles the attachment organ (Joel and Losner-Goshen, 1994; Cimmino et al., 2015). Ambio 35, 281288. Despite of this fact, Seed Certification Services in some of the countries affected, do not include in their certification standards, inspection of crop seed samples for broomrape inoculum. Federal government websites often end in .gov or .mil. However, seven broomrape species, Orobanche crenata, O. cernua, O. cumana, O. foetida, O. minor, Phelipanche aegyptiaca, and P. ramosa have specialized on attacking crops causing trouble in agriculture along Mediterranean, central and eastern Europe, and Asia (Parker, 2009). doi: 10.1006/anbo.2001.1520, Labrousse, P., Delmail, D., Arnaud, M.

In this process, cellular expansion of the root meristem is redirected from longitudinal to radial and the root apex changes its form from conical to spherical. This kind of resistance is more interesting than other mechanisms of resistance that usually involve translocation and enhanced metabolism, resulting in lower herbicide concentration in the sap of the host plant.

J. Microbiol. Breeding for broomrape resistance stands out as the most economic, easy to adopt and environmentally friendly practice. More than 40 insect herbivores from 22 families have been collected on broomrape plants but a majority of them are polyphagous without any specificity for broomrape species being some of them serious pests of important crops (Klein and Kroschel, 2002). Promotion of suicidal germination is the technique used to induce broomrape germination with synthetic molecules in the absence of a host to which broomrape can attach, a technique lethal for the parasite as the broomrape seedling is unable to acquire autotrophy.

The harvest of infested fields or blocks, because of the biology of this weed and its standing as a California Department of Food and Agriculture Class A status, is extremely ill-advised., (Article by Bob Johnson, Sacramento reporter. doi: 10.1093/jxb/err246, Fernndez-Aparicio, M., Sillero, J. C., and Rubiales, D. (2007). Broomrapes are sap-sucking 'plant pilferers' that steal their food from the roots of other . In addition to this direct effect, ethylene-producing bacteria such as Pseudomonas syringae pv. Because the haustorial organ in broomrape radicle is terminal and its growth is not resumed unless it can immediately penetrate the host, cessation of radicle elongation and haustorial induction in the absence of a host is lethal to the parasite. Aber M., Fer A., Salle G. (1983). Solarization is a thermal soil disinfestation method that shows high efficiency reducing the viability of the broomrape seed bank along with other harmful organisms to crops such as plant-parasitic nematodes, disease causing microorganisms and non-parasitic weeds. 193, 6268. We reviewed relevant facts about the biology and physiology of broomrape weeds and the major feasible control strategies. The flowers are irregularly shaped and produce single-chambered capsules that contain numerous minute seeds. Rev. In addition long lived seed banks under physiological dormancy ensure that germination will occur when a suitable host in its correct stage of development is present nearby (Rubiales et al., 2009b). Therefore an integrated and sustained management strategy composed by several control methods acting at different broomrape life stages is highly recommended to keep away the broomrape weed problem in a durable manner (Kebreab and Murdoch, 2001). The angiospermous root parasite Orobanche L. (Orobanchaceae) induces expression of a pathogenesis related (PR) gene in susceptible tobacco roots. 42, 292297.

This method consists in heating the soil through sun energy achieving temperatures above 45C, by covering a wet soil with transparent polyethylene sheets for a period of 48 weeks during the warmest season (Katan, 1981; Mauro et al., 2015). Nitrate reductase is not detectable (Lee and Stewart, 1978) and activity of glutamine synthetase is very low (McNally et al., 1983). 153, 117126.
