Control of Egyptian Broomrape in Processing Tomato: A Summary of 20 Years of Research and Successful Implementation. Parasitic plants probably evolved to recruit plant defense molecules as host recognition cues (Atsatt, 1977; Matvienko et al., 2001; Bandaranayake and Yoder, 2013). Ambio 35, 281288. Broomrape, commonly called Orobanche, is a genus of more than 200 species of herbaceous plants native to the temperate northern hemisphere. Plants (Basel). In broomrape species, the chemistry of host recognition for haustorium initiation remains uncharacterized. seed germination and radicle growth. The requirement for germination-inducing factors in order to break dormancy in parasitic seeds are bypassed by ethylene or cytokinins (which promotes ethylene biosynthesis) in Striga sp. Recent approaches for chemical control of broomrape (Orobanche spp.) Keyes, W. J., Palmer, A. G., Erbil, W. K., Taylor, J. V., Apkarian, R. P., Weeks, E. R., et al. The points of vulnerability of some underground events, key for their parasitism such as crop-induced germination or haustorial development are reviewed as inhibition targets of the broomrape-crop association. Germination response of Orobanche seeds subjected to conditioning temperature, water potential and growth regulator treatments. J. Pest Manag. (1995). 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. 6, 269275. The biological activity of AC-94, 377 [1-(3-chlorophthalimido)-cyclohexane-arboxamide]. A factor from Azospirillum brasilense inhibits germination and radicle growth of Orobanche aegyptiaca. 48, 93117. Its efficacy for broomrape cultural control can be increased if the farmer includes trap and/or catch crops as components in the rotation (Rubiales et al., 2009b). Pesta granule trials with Aspergillus alliaceus for the biocontrol of Orobanche spp. Second, broomrape weed exerts their damage underground right after attachment and therefore, contact herbicides applied after broomrape emergence, e.g., 2,4-D, had no effect on limiting yield loss in the current crop.

Biological traits in broomrape such as achlorophyllous nature, underground parasitism, the physical connection and growth synchronization with the crop, and the exclusive uptake of resources via crop vascular system rather than from the soil make broomrape control a challenging agricultural task.

Although hard seed coat has been described as dormancy mechanism in newly formed broomrape seeds (Lpez-Granados and Garca-Torres, 1996), water uptake and imbibition are performed quickly by mature seeds through the micropyle without the need of scarification (Bar-Nun and Mayer, 1993; Joel et al., 2012). 19, 753758.

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). From 1973 to 1982, the California Tomato Research Institute and the industry as a whole spent over $1.5 million on research, surveying and fumigation to achieve eradication levels of this same pest, said Zach Bagley, CTRI managing director. Pest Manag. Azospirillum brasilense is reported to inhibit broomrape radicle growth (Dadon et al., 2004). Unfortunately this technique represents another example of highly promising broomrape control strategy that has never been validated in field experiments. The first barriers are imposed at the cortex level with reinforced cell walls mediated by either protein cross-linking or with the deposition of metabolites such as suberin, or callose. doi: 10.1002/ps.993, Tank, D.

Seed respiration patterns during conditioning indicate a strong activation of metabolism. Some broomrape species are outcrossers while others are self-pollinating. It is important for broomrape to initiate parasitism in young crops otherwise host reproductive organs in the rapid seed-filling stage will be able to endure a delayed parasitism by establishing a stronger competition with parasitic sinks (Manschadi et al., 1996; Fernndez-Aparicio et al., 2009a, 2012a). 92, 1368. doi: 10.1094/PDIS-92-9-1368B. Although analytical chemistry methods have failed to detect strigolactones in parasitic plants (Liu et al., 2014), transcriptome sequencing reveals that all known strigolactone genes, both synthesis and perception are present in broomrapes with apparently full-length proteins (Pron et al., 2012; Das et al., 2015). Phytoparasitica 31, 422.

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). 38, 343349. They are quite noticeable in the desert, as males like to perch at the very top of mesquite trees (like the one above). 54, 923927. This is how can we live with this without huge yield losses. BMC Evol. Agric. Accordingly, broomrape seed conditioning induces a decrease in ABA levels (Chae et al., 2004; Lechat et al., 2012) and GA synthesis (Joel et al., 1991; Zehhar et al., 2002). Control 15, 274282.

In vitro treatments of a large range of sulfonylurea herbicides inhibit broomrape germination and radicle elongation (Hershenhorn et al., 1998; Plakhine et al., 2001). Major feasible strategies for controlling broomrape and gain productivity in the current crop are those based on cultural practices that promote host scape to parasitic damage by improving host sink competitiveness, selective chemical control of the parasite via the haustorium, and host resistance based in physical, chemical barriers and physiological incompatibility. Phytomyza orobanchia is reported to be broomrape-specific and its main action as biocontrol agent is by reduction of broomrape reproductive activity due to their feeding activity on ovules and young seeds.

The presence of strigolactone biosynthetic system in broomrapes raises the question on how the parasite performs diversified stimulant recognition in order to set the timing of germination. - A free PowerPoint PPT presentation (displayed as an HTML5 slide show) on PowerShow.com - id: 7fc2e8-Mjc3Z 3586002. Nature 455, 189194. Pseudomonas aeruginosa, P. fluorescens, Bacillus atrophaeus, B. subtilis are promising biocontrol agents targeting the growth of broomrape radicles (Barghouthi and Salman, 2010).

The evolution from autotrophic to heterotrophic mode of nutrition carried a reduction of the main broomrape vegetative organs toward vestigial versions, non-functional for autotrophy. Ann. Use of ethylene producing bacteria for stimulating of Striga spp. The advances yielded as intense research made connects the major critical steps of the life cycle of Orobanche, the external factors influencing it either through molecular dialog between the parasite and the crop or the soil and climatic environmental conditions naturally opens the way toward the potential effect of the cropping system in limiting broomrape parasitism: choice of the crop, timing, plant protection, soil perturbation, fertilization, etc. We reviewed relevant facts about the biology and physiology of broomrape weeds and the major feasible control strategies.

Structure and function of natural and synthetic signaling molecules in parasitic weed germination. Peagol and peagoldione, two new strigolactone like metabolites isolated from pea root exudates. Broomrape acts as a strong sink, depriving the host from water, mineral, and organic nutrients with the consequent negative impact on the growth of the host plant (Manschadi et al., 1996; Hibberd et al., 1998; Joel, 2000; Abbes et al., 2009). The seedling absorbs water both from the soil and from the seed endothelium, the later ensuring radicle development even in dry soil (Joel et al., 2012). Mechanical force exerted by the haustorium development toward host vascular cylinder combined with enzymatic secretion promotes the separation of host cells without their lysis (Privat, 1960; Ben-Hod et al., 1993; Sholmer-Ilan, 1993; Singh and Singh, 1993; Antonova and Ter Borg, 1996; Bar-Nun et al., 1996; Losner-Goshen et al., 1998; Veronesi et al., 2005).
