Due to their physical and metabolic overlap with the crop, their underground parasitism, their achlorophyllous nature, and hardly destructible seed bank, broomrape weeds are usually not controlled by management strategies designed for non-parasitic weeds. Interaction of light and hormone signals in germinating seeds. doi: 10.1002/ps.1742, Vurro, M., Boari, A., Pilgeram, A. L., and Sands, D. C. (2006). Plant Biol. 101, 13941399. Haustorium 54, 34. doi: 10.1006/anbo.1998.0629, Johnson, A. W., Rosebery, G., and Parker, C. (1976). The timing of germination is the most crucial event that obligated parasitic plants face along their life cycle (Figure 2C). (2002). 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. Therefore, decisions on the date of sowing has to be well-adjusted in order to balance the loss of productivity due to shorter growing period with gain of productivity due to reduced parasitism. The site is secure. Plant Dis. Z. Planzenphysiol. In addition, some modifications of host biochemistry have been described in tolerant crops inducing low performance of the parasite when attached.

They are quite noticeable in the desert, as males like to perch at the very top of mesquite trees (like the one above). Weed Sci. Close related parasitic plants of Orobanchaceae such as Striga and Triphysaria use host derived phenolic derivatives to induce haustorium differentiation (Riopel and Timko, 1995; Albrecht et al., 1999; Bandaranayake and Yoder, 2013). Both have red eyes and a feathery crest. In addition, the biological similarity between host and parasite characterizing broomrape-crop interactions is higher than in other plant pathosystems, which complicates the development of selective methods to control broomrape, without harmful effect in the crop from which it is feeding (Eizenberg et al., 2006; Hearne, 2009; Yoder and Scholes, 2010; Prez-Vich et al., 2013). Haustorial connection of broomrape with the root of a weed host In south Texas, broomrape seed germination occurs from December to February. Phytochemistry 34, 3945. Afr. However, in other broomrape-crop associations the damage induced by broomrape extends beyond assimilate diversion. Weed Res. Plant Growth Regul. 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.

Upon host detection, the broomrape radicle stops elongating and terminal haustorium is differentiated as an anchoring device. Ann. Abstract. Pest Manag. (2002). Planta 227, 125132. However, results recently arisen from a molecule screening identified phytotoxins that induce the development of anchoring device in broomrape radicles (Cimmino et al., 2014, 2015). Instead an integrated control program including a battery of broomrape-specific measurements is preferable. 38, 343349. The flowers are irregularly shaped and produce single-chambered capsules that contain numerous minute seeds. It's a cute little bird - the Phainopepla. Weed Sci. Especially common in tomatoes, hemp broomrape can parasitize a variety of vegetable crops, and its tiny seeds are usually spread by contaminated soil or crop seeds. Plant Physiol. The concept of trap crops refers to the cultivation of crop species whose root exudates exhibit high germination-inducing activity on broomrape seeds, but these species do not become infected because they are resistant to later stages of the parasitic process indirectly leading to the killing of the young broomrape seedlings due to the lack of proper host. doi: 10.1016/j.agee.2007.01.014, Gressel, J.

Broomrape, commonly called Orobanche, is a genus of more than 200 species of herbaceous plants native to the temperate northern hemisphere. 52, 8386. Solarization is a thermal soil disinfestation method that shows high efficiency reducing the viability of the broomrape seed bank along with other harmful organisms to crops such as plant-parasitic nematodes, disease causing microorganisms and non-parasitic weeds. Exogenous amino acids inhibit seed germination and tubercle formation by Orobanche ramosa (broomrape): potential application for management of parasitic weeds. 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). 65, 581587. Most species are primarily subterranean and appear aboveground only to reproduce. Natural metabolites for parasitic weed management. The consequent reduced flux of water and nutrients toward the parasite, low utilization of host-derived sucrose and lower levels of soluble proteins limits the parasitic sink strength and yield losses due to broomrape parasitism (Abbes et al., 2009). The advances yielded as intense research made connects the major critical steps of the life cycle of Orobanche, the external factors influencing it either through molecular dialog between the parasite and the crop or the soil and climatic environmental conditions naturally opens the way toward the potential effect of the cropping system in limiting broomrape parasitism: choice of the crop, timing, plant protection, soil perturbation, fertilization, etc. Sources of resistance to crenate broomrape among species of Vicia.

Inhibition of shoot branching by new terpenoid plant hormones. 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. Like most seeds, broomrape seeds are resistant to rapid microbial degradation due to phenols located in its testa (Cezard, 1973). 7:135. doi: 10.3389/fpls.2016.00135. doi: 10.1007/s00299-005-0052-y, Amsellem, Z., Zidack, N.

However, it is a long-term strategy due to the long viability of seed bank (Rubiales et al., 2009b), which requires at least a nine-course rotation in order to prevent broomrape seed bank increases (Grenz et al., 2005). Figure 1. Though, the effect of L-methionine on internal crop resistance was not studied and requires further investigation. doi: 10.1111/j.1365-313X.2007.03171.x, Klein, O., and Kroschel, J. Adv. 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. doi: 10.1023/A:1015654429456. Z. Planzenphysiol. The following sections and Table 1 review the major feasible control measures for broomrape control. 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). doi: 10.1094/MPMI-10-11-0260. Plant Physiol. doi: 10.1080/09583157.2015.1018813. (2008). 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). (2002). It is a prolific seed producer. Solute fluxes from tobacco to the parasitic angiosperm Orobanche cernua and the influence of infection on host carbon and nitrogen relations. Among the amino acids producing the highest and most consistent inhibitory effects on broomrape germination and radicle elongation, some, such as methionine are being produced in large commercial scale as animal feed supplements. Preventing the movement of parasitic seeds from infested to non-infested agricultural fields, by contaminated machinery or seed lots, is crucial (Panetta and Lawes, 2005). Mater. Plant J.

Ehleringer, J. R., and Marshall, J. D. (1995). The .gov means its official. Broomrapes are plant-parasitic weeds which constitute one of the most difficult-to-control of all biotic constraints that affect crops in Mediterranean, central and eastern Europe, and Asia. 65, 453459. Germination stimulants of Phelipanche ramosa in the rhizosphere of Brassica napus are derived from the glucosinolate pathway. (2005).

Once broomrape has established connection with the vascular system of its hosts, broomrape management should be performed quickly to abort at earlier stages the strong parasitic sink for nutrients and water. Simulation of integrated control strategies for Orobanche spp. (A) Fructification and dehiscence of capsules containing mature seeds; (B) microscopic view of a seed (size ranging 0.22 mm) that undergoes sucessive dispersal, primary dormancy and annual release of secondary dormancy; (C) broomrape embryo does not develop morphologycaly identified cotyledons or shoot meristem and upon host-induced germination, only a radicle emerges from the seed with the function of searching and contacting the host root; (D) upon haustorial induction, the radicle stops elongating and a single terminal haustorium is differentiated. in Mediterranean agriculture. The predictability of establishment on perennial hosts is high and therefore wild broomrape species feeding off perennial plants have narrow host ranges. Underground Mechanisms of Parasitism and Associated Strategies for their Control: A Review. Plant Physiol.

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. 81, 779781. Systemic translocation of nanoencapsulated herbicides could improve this herbicidal approach (Prez-de-Luque and Rubiales, 2009). High osmotic potential in roots and drop in amino acid levels in the phloem has been reported in tolerant varieties of faba bean in response to broomrape parasitism. doi: 10.1007/s11103-008-9429-y. Thorie Elmentaire de la Botanique. Although hard seed coat has been described as dormancy mechanism in newly formed broomrape seeds (Lpez-Granados and Garca-Torres, 1996), water uptake and imbibition are performed quickly by mature seeds through the micropyle without the need of scarification (Bar-Nun and Mayer, 1993; Joel et al., 2012). doi: 10.1002/ps.1735, Hershenhorn, J., Eizenberg, H., Dor, E., Kapulnik, Y., and Goldwasser, Y. Successful reduction of broomrape parasitism in the current crop is obtained by intercropping host species with inhibitory species of cereals, fenugreek, or berseem clover (Fernndez-Aparicio et al., 2007, 2008b, 2010a). Mller-Stver, D., Buschmann, H., and Sauerborn, J. This prevents broomrape parasitism from taking place, maintaining the seed bank dormant and reducing the rate of seed bank replenishing.

Branched broomrape is so destructive in tomatoes that if it is detected in a growers field, quarantine regulations require that the crop be destroyed and the field be disked under, and common sense dictates that a grower rotate out of host crops for many years, said Brad Hanson, UC Cooperative Extension weed specialist, Department of Plant Sciences, UC Davis. 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). Broomrape seed has been documented to last in the soil for at least 35 years.. In order to increase their applicability in low-input crops, the development of synthetic analogs of hormones would constitute a cheap alternative to natural bioregulators for seed bank control of weeds in general and parasitic weeds in particular. 30, 533591.

The use of those amino acids as pesticide is classified by the United States Environmental Protection Agency as innocuous to public and environment health (USEPA, 2004). Saghir, A. R. (1986). 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. Sustain. Broomrapes produce little or no chlorophyll; instead, they draw nourishment from the roots of other plants by means of small suckers called haustoria. 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).
