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.. 60, 295306. Sources of natural resistance based on reduced release of haustorium-inducing factors is a doubly interesting strategy to inhibit broomrape parasitism because not only it prevents broomrape parasitism in the current crop, but also it promotes the demise of the seed bank by promoting suicidal germination. J. Linn. Abstract. Manage. Still, as the parasite is synchronized on the crop development this means in some cases that the change disfavoring the parasite could also limit the maximum potential yield for the crop. Despite the reports of broomrape inefficient machinery for nitrogen assimilation and broomrape dependence for host-derived organic forms of nitrogen demonstrated by the fact that broomrape growth is arrested when feeding on host cultivars with decreased amino acid-phloem levels (Abbes et al., 2009), inhibition of enzymes at the top of amino-acid biosynthetic pathway by means of either direct inhibitory action of herbicides (Gressel, 2009) or by feedback inhibition induced by amino-acid end-products (Vurro et al., 2006) are able to kill broomrape. Saghir, A. R. (1986). 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. seed germination and radicle growth. The apical cells in the radicle apex develop into intrusive cells, which successively invade host root cortex, endodermis, and the central cylinder. doi: 10.1016/0031-9422(95)00594-3, Bar-Nun, N., and Mayer, A. M. (1993). 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). Plant Cell Physiol. 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. PDF BSA-seq mapping reveals major QTL for broomrape resistance in four (2010). Weed Sci. (2008). The host reproductive sinks compete earlier and stronger against the parasitic sink and in consequence less nutritive resources are allocated to the parasite (Manschadi et al., 1996). Therefore broomrape seeds timely gain sensitivity for host chemodetection by means of conditioning (Lpez-Granados and Garca-Torres, 1996). Suttle, J. C. (1983). Its high cost per surface unit makes this method not readily applicable at large scale (Joel, 2000). Agric. (2002). Bot. In general, parasitized crops suffer from reductions in total biomass at the greatest expense to the reproductive tissue (Barker et al., 1996; Manschadi et al., 1996; Lins et al., 2007). For example, soil application of uniconazole, a triazole that is commercially used for growth regulation has proved to reduce parasitism by inhibiting seed conditioning and subsequent germination (Joel, 2000; Zehhar et al., 2002; Song et al., 2005; Lechat et al., 2012). Broomrape species display high diversity with regard to their host range. Figure 1. Based on the results obtained in their greenhouse experiments, these authors recommended field doses of 1.6 kg ha1 for crop densities of 32,000 tobacco plants ha1. Upon host detection, the broomrape radicle stops elongating and terminal haustorium is differentiated as an anchoring device. Front. Weed Res. Sudan J. Agric. 93, 10391051. Commercially available as Bion, field doses of 0.8 kg ha1 are recommended to inhibit P. ramosa parasitism in hemp and tobacco (Gonsior et al., 2004), crops for which resistant varieties are not available. In other pathosystems, amino acids such as D-L--amino-n-butyric acid or L-methionine induce resistance in crop plants against pathogen attack. doi: 10.1046/j.1365-3040.1998.00272.x, Hibberd, J. M., Quick, W. P., Press, M. C., Scholes, J. D., and Jeschke, W. D. (1999). Positive regulation: (1) production by each flower scape of hundreds of thousands of seeds able to survive in the soil for more than 10 years; (2) production by the host plant of strigolactones or glucosinolates that stimulate seed germination (blue arrows). Evaluation of amino acids as turfgrass nematicides. Due to the small size of the seeds and their inability to develop autotrophy, the establishment probability of broomrape seedlings is very low. doi: 10.1111/j.1365-3180.2009.00742.x, Rubiales, D., Fernandez-Aparicio, M., and Rodriguez, M. J. Fig. and transmitted securely. Exp. Cala, A., Rial, C., Fernandez-Aparicio, M., Molinillo, J. M. G., Varela, R. M., Rubiales, D., et al. In addition to the toxic effects on broomrape seed and seedling, fertilization can protect crops from broomrape parasitism by means of down-regulating the crop synthesis and exudation of strigolactones, the most potent germination-inducing factors for broomrape.

This is an open-access article distributed under the terms of the Creative Commons Attribution License (CC BY). However, hyphae of specific pathogens are able to penetrate the seed coat of broomrape dormant seeds, dissolving the endosperm cell walls and metabolizing the cytoplasm. They have been traditionally considered the exception in parasitic Orobanchaceae that do not require host factors for haustorium initiation (Joel and Losner-Goshen, 1994; Bandaranayake and Yoder, 2013). Evaluation of Fusarium spp. The opposite agricultural practice deep-plowing, has been suggested to bring seeds of parasitic weeds to a depth with less oxygen availability and therefore a reduction in its germination capacity (Van Delft et al., 2000). Sands, D. C., and Pilgeram, A. L. (2009). This is a short and delicate stage where the parasite either connects with the host or dies due to nutrient exhaustion.

Plant Growth Regul. This lead us to build the list of the major feasible components that a model designed to quantify the effects of cropping systems on pest dynamics should include for specific broomrape control.

Control 28, 110. Control the Striga conundrum. Broomrapes counteract the high risk of failure in establishment on a host with highly evolved mechanisms of survival. 111, 193202. Their absolute dependence on host-derived nutritive resources for successful seedling establishment and consequent growth makes necessary the synchronization of parasitic germination with the growth of its host. The broomrape plant is small, from 10-60 cm tall depending on species. 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). 65, 560565. This effect may not be applicable to those broomrape species with preference for classes of germination-inducing factors other than strigolactones (Joel et al., 2011; Auger et al., 2012). (2001). Soil management affects the success of broomrape seeds in becoming established on the host and then the longevity of broomrape seed bank. J. Pest Manag.

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. 51, 44874503. Mediterr. A better understanding in the roles of major hormones in the process of broomrape germination would facilitate the design of feasible control strategies based on either inhibition of broomrape germination during crop cultivation or promotion of suicidal germination in the absence of the crop. Effect of branched broomrape (Orobanche ramosa) infection on the growth and photosynthesis of tomato. Host plant resistance against broomrapes (Orobanche spp. Phytochemistry 72, 624634.

They elicit GA-like germination activity in dormant seeds of several autotrophic plant species (Suttle and Schreiner, 1982; Metzger, 1983), constituting a cheap alternative to natural bioregulators for weed seed bank control (Suttle, 1983). However, the overall productivity of the host-parasite system is also reduced due to the shorter growing period being detrimental for crop yield. Planta 225, 10311038. The advantage of this approach using fungi is that it can be used in absence of host cultivation (Thomas et al., 1999). Ann. 49, 2333. Rhizobium leguminosarum induces defense mechanisms based on elevated induction of the phenylpropanoid pathway conferring mechanical and chemical barriers to the parasite penetration (Mabrouk et al., 2007a,b,c, 2010). Dor, E., and Hershenhorn, J. Broomrape (Orobanche crenata Forsks.) Rich, P. J., Grenier, C., and Ejeta, G. (2004). Instead, broomrapes are in current state of intensification and spread due to lack of broomrape-specific control programs, unconscious introduction to new areas and may be decline of herbicide use and global warming to a lesser degree. Broomrape | Infonet Biovision Home. broomrape and bursage relationship - 1atlanticfunding.com Sci. On the contrary, they must be highly susceptible, as the farmer is the one with the role of stopping the parasitic process by harvesting the catch crop as a green vegetable before the parasite emerges. Ghersa, C. M., and Martinez-Ghersa, M. A. Abiotic inducers of SAR thus represent an innovative approach to control broomrape parasitism. Plants (Basel). In absence of host detection the continuation of wet conditions allows broomrape seeds to enter again in deeper levels of dormancy, from which they will emerge upon the new onset of sequenced dry/wet seasons carrying new opportunities to encounter suitable hosts (Kebreab and Murdoch, 1999; Lpez-Granados and Garca-Torres, 1999). News Bull. 29, 867871. Control 2 291296. This approach is based on the selection of naturally occurring mutants that overproduce and excrete an enhanced amount of specific amino acid with broomrape inhibition properties on seed germination and radicle growth (Vurro et al., 2006; Sands and Pilgeram, 2009). The reduction of ABA:GA ratio induced by stratification (conditioning) is enough to break dormancy and promote germination in dormant seeds of non-parasitic weeds but it is not enough for broomrape, which requires a further decrease in ABA levels induced by the activation of the ABA catabolic gene PrCYP707A1 (Lechat et al., 2012).

Instead, broomrapes are in current state of intensification and spread due to lack of broomrape-specific control programs, unconscious introduction to new areas and may be decline of herbicide use and global warming to a lesser degree. A quantitative model for loss of primary dormancy and induction of secondary dormancy in imbibed seeds of Orobanche spp. Successful reduction of broomrape parasitism in the current crop is obtained by intercropping host species with inhibitory species of cereals, fenugreek, or berseem clover (Fernndez-Aparicio et al., 2007, 2008b, 2010a). Striga hermonthica MAX2 restores branching but not the very low fluence response in the Arabidopsis thaliana MAX2 mutant. Symplasmic sieve element continuity between Orobanche and its host.
