Molecular responses of Lotus japonicus to parasitism by the compatible species Orobanche aegyptiaca and the incompatible species Striga hermonthica. They are attempting to learn if a timely application of an herbicide at a rate high enough to stunt the broomrape, but low enough to spare the tomatoes, can be an effective strategy to minimize crop losses. doi: 10.1016/j.jplph.2010.08.011, Losner-Goshen, D., Portnoy, V. H., Mayer, A. M., and Joel, D. M. (1998). (2009). With target-site resistance, the herbicide translocates unmetabolised to the underground broomrape via the haustorium inflicting its suppressive action in the parasite (Gressel, 2009). As a consequence of the high risk of establishment failure in the seedling, broomrapes have evolved germination strategies that predict establishment potential based on host chemodetection (Vaucher, 1823).

Phosphorus deficiency in red clover promotes exudation of orobanchol, the signal for mycorrhizal symbionts and germination stimulant for root parasites. In Vitro Cell. Haustorium allows broomrape to attack crops by successive functions, first as host-adhesion organ, and subsequently as invasive organ toward host vascular system where finally establishes vascular continuity allowing the parasite to withdraw water and nutrients from the host (Riopel and Timko, 1995; Joel, 2013). 72, 564574. 29, 867871.

Fusarium nygamai a potential bioherbicide for Striga hermonthica control in sorghum. Besides date of sowing, nutrient management can promote both tolerance and increased resistance in crops to broomrape parasitism (Parker, 2009; Labrousse et al., 2010). 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).

Should you discover broomrape in a field, please contact the grower immediately, who should in turn contact the respective county agricultural commissioner. (1995).

During the host penetration process, broomrape does not dissolve the host cells in its way toward vascular cylinder. (1996). The efficient action of the biological control agent will depend on its ability to remain active over a large range of ecological conditions (Aly, 2007). After host adhesion to host root surface the haustorium develops its invasive function of penetrating the host root (Figure 2E).

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). New Phytol. 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).

Responsiveness of Orobanche ramosa L. seeds to GR24 as related to temperature, oxygen availability and water potential during preconditioning and subsequent germination. The broomrape seed bank efficiency to initiate parasitism can be reduced by incorporation to the soil of several pathogens able to infect preattached broomrape stages such as Fusarium sp. Am. Sci. The advantage of this approach using fungi is that it can be used in absence of host cultivation (Thomas et al., 1999). Though, the effect of L-methionine on internal crop resistance was not studied and requires further investigation. 43, 808815. Plant Commun.

Mabrouk, Y., Mejri, S., Hemissi, I., Simier, P., Delavault, P., Saidi, M., et al. Additional mechanisms that could contribute to the selective action of host-derived strigolactones in broomrape germination could be (1) variations of molecular structure between host-derived and parasite-encoded strigolactones conferring different specificity for different biological functions or (2) different spatial localization inside the broomrape seed for functions of strigolactone detection and strigolactone synthesis (Das et al., 2015). Bot. Although broomrape pre-vascular connections benefits from host nutrients, the growth of broomrape in its way toward vascular cylinder is mainly sustained by consumption of seed reserves (Aber et al., 1983; Joel and Losner-Goshen, 1994; Joel, 2000).

EM 8884-E Reprinted August 2008 important rotational crop in grass seed production systems. The predictability of establishment on perennial hosts is high and therefore wild broomrape species feeding off perennial plants have narrow host ranges. doi: 10.1111/j.1365-3180.2009.00738.x, Prez-de-Luque, A., Jorrn, J., Cubero, J. I., and Rubiales, D. (2005). The majority of broomrape species are botanical wonders parasitizing wild host plants in natural ecosystems. 4 - Iowa State University check engine light on and off Serotinous species in North American deserts have evolved similar seed retention syndromes as . Target-site resistances have been successfully developed in crops either by classical breeding such as sunflower, by screening mutagenized crop populations such as the case of oilseed rape or by transgenic techniques such as tomato, tobacco, carrots, and oilseed rape (Joel et al., 1995; Aviv et al., 2002; Slavov et al., 2005; Tan et al., 2005). 2. A., Sauerborn J. More than 40 insect herbivores from 22 families have been collected on broomrape plants but a majority of them are polyphagous without any specificity for broomrape species being some of them serious pests of important crops (Klein and Kroschel, 2002). Other interesting molecules that hamper the ability of broomrape radicle to reach the host have been recently discovered from different microbial and plant origins (Fernndez-Aparicio et al., 2013; Cimmino et al., 2014). 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. Curr. Biological regulation of broomrapes. In vitro treatments of a large range of sulfonylurea herbicides inhibit broomrape germination and radicle elongation (Hershenhorn et al., 1998; Plakhine et al., 2001). Effect of amino acid application on induced resistance against citrus canker disease in lime plants. Bot. 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). Intercropping systems cultivate simultaneously more than one species in close association to take agronomic advantage of biodiversity, competition, and complementarity between them. The majority of strategies aimed to manage autotrophic weeds do not necessarily work for broomrapes and those that provide a degree of success for broomrape need to be optimized for each broomrape-crop species combination, local environmental conditions and broomrape population.

Our editors will review what youve submitted and determine whether to revise the article. Third, broomrape underground attachments do not take herbicides from the soil but only systemically from the host and therefore, this strategy is limited to systemic herbicides applied to herbicide-resistant crop varieties that do not metabolize the herbicide into inactive forms. Funct. Striga seed avoidance by deep planting and no-tillage in sorghum and maize. Four broomrape features define the post-attachment herbicidal strategy in comparison with non-parasitic weeds.
