Maintenance of relative low levels of those amino acids in tubercles either by low levels of synthetase activities (McNally et al., 1983) and or their rapid turnover of host-derived amino acids, establishes a decreasing concentration gradient that favors the unloading of amino acids into the parasite (Abbes et al., 2009). 34, 610619.

One step in the research is to learn if the tomatoes can grow through low level applications of the candidate herbicides. doi: 10.1094/MPMI.1998.11.6.530, Xie, X., Yoneyama, K., and Yoneyama, K.

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. by . 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). (2007).

Low strigolactone root exudation: a novel mechanism of broomrape (Orobanche and Phelipanche spp.) 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. 51, 702707.

Biol. Variability of interactions between barrel medic (Medicago truncatula) genotypes and Orobanche species. Kusumoto, D., Goldwasser, Y., Xie, X., Yoneyama, K., and Takeuchi, Y. (2001). Depending on the genetic background of the resistant host, the intrusive cells of broomrape seedling can be stopped at three different levels in their way of penetration through the root layers to achieve connection with the host vascular system. broomrape and bursage relationship. The major strategy that specifically impedes the broomrape capacity to penetrate the host once the radicle has made contact with host root, is based on the use of host resistance, either genetic resistance obtained by breeding (Prez-de-Luque et al., 2009; Yoder and Scholes, 2010), or induced resistance by abiotic or biotic agents (Gonsior et al., 2004; Kusumoto et al., 2007).

The external cell layer at the root tip differentiates into a papillate cell layer forming an adhesion epithelium (Figure 2D). Res. (2007). Pest Manag. 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. Ann. 25, 375387. 81, 779781. doi: 10.1021/jf5027235, Fernndez-Aparicio, M., and Rubiales, D. (2012). 93, 300313. Phytopathol. J. Evol. Bot. (2007b). "It is a prolific seed producer. Phosphorus deficiency in red clover promotes exudation of orobanchol, the signal for mycorrhizal symbionts and germination stimulant for root parasites. Plant Growth Regul. 8600 Rockville Pike Promising new control strategies have been investigated though the majority of them are under development or remain as prototypes to which farmers have not access. 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). Effects of environment and sowing date on the competition between faba bean (Vicia faba) and the parasitic weed Orobanche crenata. Once a field is infested, controlling the broomrape seed bank is very difficult due to its high resilience. If left uncontrolled during one or a few seasons, broomrape weeds build a hardly destructible seed bank in agricultural soils that further renovates at a rate of millions of seeds per ha each year a susceptible crop is infested.

Haustorium-inducing factors are structurally similar to allelopathic phytotoxins and gene expression of parasitic radicles exposed to haustorium-inducing factors is similar to that after radicle is exposed to phytotoxins (Tomilov et al., 2006). Orobanche crenata in UK- an update. Careful selection of the non-host component in the intercrop is, however, required as some plant species can act as non-host facilitators and therefore increase the severity of broomrape infection in the host component (Gibot-Leclerc et al., 2013). 11, 240246. Plant J. Gene expression analysis could be indicating that parasitic plants down-regulate their synthesis of strigolactones at the end of conditioning period, and perhaps the creation of that internal deficit for broomrape-encoded strigolactones contributes to the broomrape sensitivity for external, host-derived strigolactones at the time of host detection (Das et al., 2015). 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). 53, 107117. doi: 10.1093/annbot/mcm148, Labrousse, P., Arnaud, M. C., Griveau, Y., Fer, A., and Thalouarn, P. (2004). 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).

Besides the demethylation of PrCYP707A1 promoter required for host-dependent PrCYP707A1 expression, the high levels of global DNA demethylation observed at the end of conditioning period suggest that the epigenetic process occurring during the conditioning phase may be targeting other unknown molecules during conditioning.
