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.

The promotion of germination of dormant weed seeds by substituted phthalimides and gibberellic acid.

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). This structure is described as the external anchorage device of the pre-penetrated haustorium to the host surface (Joel and Losner-Goshen, 1994). 81, 319326. seed germination and radicle growth. Multiple KAI2d genes across broomrape species genomes may allow diversified recognition of root exudates corresponding with suitable hosts (Conn et al., 2015). 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).

Although some examples of successful control do exist for some crops, the majority of commercially available control methods are either not fully effective or not applicable to many of the affected crops, especially in the case of low-input crops (Joel, 2000). (2009). 33, 787793. (2008). Mechanical force exerted by the haustorium development toward host vascular cylinder combined with enzymatic secretion promotes the separation of host cells without their lysis (Privat, 1960; Ben-Hod et al., 1993; Sholmer-Ilan, 1993; Singh and Singh, 1993; Antonova and Ter Borg, 1996; Bar-Nun et al., 1996; Losner-Goshen et al., 1998; Veronesi et al., 2005).

Underground Mechanisms of Parasitism and 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. Nanotechnology for parasitic plant control. 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). doi: 10.1111/j.1365-3180.1996.tb01669.x.

As the broomrape seeds are long-lived and difficult to detect, infested fields are usually quarantined to prevent further spread. Among the reviewed strategies are those aimed (1) to reduce broomrape seed bank viability, such as fumigation, herbigation, solarization and use of broomrape-specific pathogens; (2) diversion strategies to reduce the broomrape ability to timely detect the host such as those based on promotion of suicidal germination, on introduction of allelochemical interference, or on down-regulating host exudation of germination-inducing factors; (3) strategies to inhibit the capacity of the broomrape seedling to penetrate the crop and connect with the vascular system, such as biotic or abiotic inhibition of broomrape radicle growth and crop resistance to broomrape penetration either natural, genetically engineered or elicited by biotic- or abiotic-resistance-inducing agents; and (4) strategies acting once broomrape seedling has bridged its vascular system with that of the host, aimed to impede or to endure the parasitic sink such as those based on the delivery of herbicides via haustoria, use of resistant or tolerant varieties and implementation of cultural practices improving crop competitiveness. 109, 181195.

Scientists Dr Chris Thorogood at the University of Oxford Botanic Garden, and Dr Fred Rumsey at London's Natural History Museum have just described a new form of a strange parasitic 'vampire' plant known as 'common broomrape'.

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.. Technol. The length and temperature required to promote seed conditioning depends on the broomrape species but are usually described under laboratory conditions in a range of 412 days at a temperature of 1923C, in dark and humid conditions (Kebreab and Murdoch, 1999; Gibot-Leclerc et al., 2004; Lechat et al., 2012). The presence of strigolactone biosynthetic system in broomrapes raises the question on how the parasite performs diversified stimulant recognition in order to set the timing of germination. Polyphenols, including the new peapolyphenols AC, from root exudates stimulate Orobanche foetida seed germination. 47, 27.

One could even imagine situation Biol. Researchers are conducting the germination studies to develop a model for the right application time in the UC Davis Contained Research Facility, which is designed to prevent escape of the weed. The control of broomrape by mycoherbicides does not so far provide the level of control required in highly infested soils (Aly, 2007). Aber M., Fer A., Salle G. (1983). A role for IAA in the infection of Arabidopsis thaliana by Orobanche aegyptiaca. (2012). Israeli researchers developed a temperature/moisture model for application of low rates of an ALS inhibitor on processing tomatoes. These connections are probably developed from simultaneous differentiation of adjacent host and parasite cells to xylem elements (Drr, 1997). 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. doi: 10.1111/j.1365-313X.2007.03171.x, Klein, O., and Kroschel, J. 122, 275281. 65, 492496. The embryos in broomrapes have not morphologically identified cotyledons or shoot meristems and upon germination, only a radicle emerges through the seed coat with the only function of reaching and invading the host. One plant can produce over 100,000 seeds only 0.3 millimeters long. Plant Cell Physiol. doi: 10.1111/j.1365-3180.1995.tb01641.x, Gomez-Roldan, V., Fermas, S., Brewer, P. B., Puech-Pages, V., Dun, E. A., Pillot, J. P., et al. For instance, root exudates of field pea induces high germination of the very destructive broomrape species O. crenata, O. foetida, O. minor, and P. aegyptiaca, however, it only becomes infected by O. crenata therefore pea may theoretically be a good trap crop against O. foetida, O. minor, and P. aegyptiaca but not for O. crenata infested field (Fernndez-Aparicio and Rubiales, 2012).
