Weed Res. For each broomrape-crop association, broomrape germination potential is defined by the combination of both, the stimulatory capability of crop root exudates and the sensitivity of parasitic receptors to recognize specific forms of germination-inducing factors (Fernndez-Aparicio et al., 2008a, 2009b, 2011). 44, 284289. Clipboard, Search History, and several other advanced features are temporarily unavailable. Parker, C. (2014). Effect of fungal and plant metabolites on broomrapes (Orobanche and Phelipanche spp.) Sources of natural resistance based on low exudation of germination-inducing factors exist in legumes and sunflower and are highly effective in inhibiting broomrape weed parasitism (Labrousse et al., 2001, 2004; Rubiales et al., 2003b, 2009a; Prez-de-Luque et al., 2005; Sillero et al., 2005; Abbes et al., 2010; Fernndez-Aparicio et al., 2012b, 2014). 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). Nitrogen and carbon relationships between the parasitic weed Orobanche foetida and susceptible and tolerant faba bean lines. Hot air temperature and clear skies are required during the solarization period. It has no root cap and does not develop procambium or conductive tissues (Joel and Losner-Goshen, 1994).

M., and Mayer, A. M. (1993). A variety of methods have been developed to specifically neutralize broomrape pre-attached development though the majority of them are not commercially implemented because they are still at the stage of development or have not proved enough efficiency or applicability for large scale crops. J. doi: 10.1046/j.1365-3180.2002.00306.x. 2. 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. 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. We reviewed relevant facts about the biology and physiology of broomrape weeds and the major feasible control . Broomrape seed bank presents annual cycles of non-deep physiological dormancy induced by seasonal changes in climatic conditions. The new nomenclature of Orobanche and Phelipanche. As alternative, transgenic resistant crops have been engineered with broomrape-inducible expression of toxins specifically targeting the penetrating broomrape seedling.

Due to their achlorophyllous nature, broomrapes are constrained to obtain their nutritional resources by feeding off other plants using the haustorium, an organ unique in parasitic plants through which the parasite diverts water and nutrients from the host (De Candolle, 1813; Kuijt, 1969; Musselman and Dickison, 1975; Westwood, 2013). Sudan J. Agric. doi: 10.1016/S0261-2194(00)00100-9, Joel, D. M. (2009). However, when Vurro et al. 33, 267349. Mohamed, K. I., Papes, M., Williams, R., Benz, B. W., and Peterson, A. T. (2006). An important piece of this research is identifying the best time to apply an herbicide to slow down the broomrape with a minimum of damage to the tomatoes.

The significance of this structure in broomrape parasitism requires further investigation. Neither nitrogen nor lipid content change significantly during conditioning, while carbohydrate metabolism and protein synthesis seems to be crucial (Bar-Nun and Mayer, 1993, 2002; Mayer and Bar-Nun, 1994, 1997). Broomrape seed bank remains viable in the soil for many years until germination is triggered by the coincidence of several physical and chemical factors that are indicative of environmental conditions for successful seedling establishment: i.e., the nearby growth of a host plant in a physiological stage susceptible for broomrape invasion and subsequent parasitic reproductive growth (Linke and Saxena, 1991; Lpez-Granados and Garca-Torres, 1996, 1999).

Sucrose is also metabolized to starch that is accumulated in the broomrape storage organ, the tubercle (Abbes et al., 2009; Draie et al., 2011).

J., Rubiales, D., Ocampo, J. This is a crop phyto trial, and so far, so good, Fatino said as he looked over tomato plots in test fields on the UC Davis campus that had been treated with very low rates of a number of weed killers. The Broomrape family comprises more than 2000 species of annual and perennial herbs or shrubs, nearly all of which are parasitic on the roots of other plants. 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. Intercropping systems cultivate simultaneously more than one species in close association to take agronomic advantage of biodiversity, competition, and complementarity between them. Suttle, J. C.

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. Plants (Basel). 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.

However, exogenous application of GA alone is not sufficient to promote broomrape germination (Takeuchi et al., 1995; Chae et al., 2004) and strigolactone-mediated ABA catabolism in conditioned seeds is required to trigger germination (Lechat et al., 2012).
