broomrape and bursage relationship

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). Unfortunately this technique represents another example of highly promising broomrape control strategy that has never been validated in field experiments. Germinating seeds of the root parasite Orobanche aegyptiaca Pers. New Phytol. Haustorium 53, 13. doi: 10.1094/MPMI-01-12-0006-R, Aviv, D., Amsellem, Z., and Gressel, J. doi: 10.1016/j.agee.2007.01.014, Gressel, J. 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. The first function of haustorium is as adhesion organ to host root surface mediated by a papillae cell layer; (E) adhesion to the root 3 days after germination induction; (F) upon vascular connection with the host, broomape initiates the development of the tubercle, the broomrape storage organ for host-derived nutrients. 49 239248. Effect of fungal and plant metabolites on broomrapes (Orobanche and Phelipanche spp.) Emerged small broomrape stalks in a red clover seed production eld. Engineering of virulence-enhanced mycoherbicides is another approach of great interest. (2015). 83, 453458. Sauerborn (1991) estimated that 16 million ha in Mediterranean and West Asia regions risked being infested. Bagley urged growers and pest control advisors to be vigilant in avoiding spread of this weed to new fields. Like most seeds, broomrape seeds are resistant to rapid microbial degradation due to phenols located in its testa (Cezard, 1973). If successful, these studies could develop a strategy to limit the damage from broomrape if it becomes established and the strict quarantine is lifted. Food Chem. One future development would be to evaluate what could be the emerging risk at cultivating different crops, one of which may stimulate germination while the other offers opportunities for haustorium fixation. Post-germination development in broomrape could be probably regulated by their own broomrape-encoded strigolactones as it occurs in the close related parasite Striga hermonthica or in non-parasitic plants (Liu et al., 2014; Das et al., 2015). 42, 292297.

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). doi: 10.1093/jxb/err246, Fernndez-Aparicio, M., Sillero, J. C., and Rubiales, D. (2007). Seed respiration patterns during conditioning indicate a strong activation of metabolism. In addition it also varies considerably in crops growing under different physiological status, growth stages and growing seasons, allowing broomrape to synchronize its germination with physiologically suitable hosts (Lpez-Granados and Garca-Torres, 1996; Yoneyama et al., 2007a,b; Fernndez-Aparicio et al., 2009b, 2014; Xie et al., 2010).

Refined formulations and encapsulations of fungal propagules increase efficacy in biocontrol by reducing desiccation or microbial competition (Amsellem et al., 1999; Quimby et al., 1999; Kroschel et al., 2000; Mller-Stver, 2001; Aybeke et al., 2015). Cimmino A, Fernndez-Aparicio M, Andolfi A, Basso S, Rubiales D, Evidente A. J Agric Food Chem. In addition, the parasitic-specific receptor KAI2d that enables host detection in broomrapes has recently been identified. A., and Rubiales, D. (2010a). 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). (2000). Metabolites. PrCYP707A1, an ABA catabolic gene, is a key component of Phelipanche ramosa seed germination in response to the strigolactone analogue GR24. Food Chem. A novel metabolite, ryecyanatine-A recently isolated from rye (Secale cereale L.), presents potential for broomrape control by promoting rapid cessation of broomrape radicle growth and therefore inhibiting its ability to reach the host. Some of the strategies discussed in previous sections such as biological control maintain their control action at post-attachment stages and will not be discussed again in this section. 47, 27.

Bioprotection mechanisms of pea plant by Rhizobium leguminosarum against Orobanche crenata.

A better understanding of the biochemistry of host recognition in broomrape will facilitate the generation of control strategies targeting the haustorium development. Successful broomrape control should target the underground broomrapes at their earlier life stages, prior attachment or as soon as it attach to the host, because of their highest vulnerability at those stages and the avoidance of yield loss in the current crop.

The ability of L-methionine to stop the entrance of broomrape intrusive cells into the host-root layers has not been studied. (2001). Copyright 2016 Fernndez-Aparicio, Reboud and Gibot-Leclerc. Biol. Therefore, it may be possible to achieve broomrape control by fooling the parasite with the delivering to the soil of synthetic analogs of the original host-derived germination-inducing factors such as strigolactones (Johnson et al., 1976). Impact of Egyptian broomrape (Orobanche aegyptiaca (Pers.) Broomrape management elsewhere Israeli cooperators have been working on broomrape management for several decades Eizenberg, Goldwasser, and others Weed is not eradicated, but is managed to an acceptable level Management is based on carefully -timed and -placed herbicides to disrupt key broomrape life stages 65, 478491. Soil fumigation with methyl bromide has been proved one of the most effective methods to eradicate broomrape seed bank, but this chemical has been banned from use due to its toxic effects on the environment (Joel, 2000; Hershenhorn et al., 2009). 22, 937947. 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). 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.

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. *Correspondence: Mnica Fernndez-Aparicio, [email protected], View all Novel approaches can increase broomrape control by fungi. This strategy requires a careful calibration of doses and timing depending on the host crop and underground phenology of broomrape determined by local conditions and crop (Hershenhorn et al., 1998, 2009; Eizenberg et al., 2006). The first step of conditioning promotes in the parasitic seed receptors the required sensitivity for the second step of host detection (Musselman, 1980; Kebreab and Murdoch, 1999; Lechat et al., 2012, 2015; Murdoch and Kebreab, 2013). We have seen that several opportunities to stop the cycle of the parasite have been explored. 8600 Rockville Pike J. Agric.

Systemic translocation of nanoencapsulated herbicides could improve this herbicidal approach (Prez-de-Luque and Rubiales, 2009). (1999). Rev. 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. 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.

Eizenberg, H., Aly, R., and Cohen, Y. 125, 9297. The model was developed in greenhouse studies and validated in the field during three growing seasons. Shortly after host penetration and connection, the parasite begins its heterotrophic growth at the expense of host resources. 35, 445452.
