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. Bot. Low strigolactone root exudation: a novel mechanism of broomrape (Orobanche and Phelipanche spp.) Dev. The re-emergence of branched broomrape in California is of concern to the processing tomato industry as: 1) the experience in other regions of the world has demonstrated the extreme vulnerability of tomato to branched broomrape parasitism, 2) broomrapes seem likely to rapidly establish and spread in California because of the similarity to the species' native climate, (3) repeated cultivation .

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. Being deprived of the initiation of autotrophic mode of life, the growth of broomrape seedling toward the host is only sustained by water absorption and remobilization of reserve nutrients from the seed perisperm and endosperm (Joel, 2000; Joel et al., 2012). doi: 10.1017/S0960258510000371, Fernndez-Aparicio, M., Cimmino, A., Evidente, A., and Rubiales, D.

The taxonomy of the group is somewhat contentious, and the American species of broomrape are sometimes placed in the genus Aphyllon. Crops that reach their seed filling period earlier than broomrape initiates its underground bud development are able to restrict parasitic sink and endure parasitic damage (Manschadi et al., 1996; Grenz et al., 2005; Fernndez-Aparicio et al., 2009a, 2012a). The metabolic activity of the seed conditioning in broomrape has been characterized in terms of patterns of respiration, synthesis and turnover of proteins, metabolism of nitrogen, carbohydrates and lipids and hormonal balance. doi: 10.1111/j.1365-3180.2009.00739.x, Hershenhorn, J., Goldwasser, Y., Plakhine, D., Lavan, Y., Blumenfeld, T., Bucsbaum, H., et al. The broomrape plant is small, from 10-60 cm tall depending on species. If this works, it will be easy to implement through the fertilizer system.. 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. Bot.

SA promotes resistance to broomrape. Manschadi, A. M., Kroschel, J., and Sauerborn, J. The crops affected depend on the host range of the broomrape species considered but in general, those in the Asteraceae, Brassicaceae, Apiaceae, Fabaceae, or Solanaceae such as sunflower, oilseed rape, carrot, faba bean, or tomato among many others, sustain the major attacks (Parker and Riches, 1993). "It is a prolific seed producer. 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). 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).

However, seven broomrape species, Orobanche crenata, O. cernua, O. cumana, O. foetida, O. minor, Phelipanche aegyptiaca, and P. ramosa have specialized on attacking crops causing trouble in agriculture along Mediterranean, central and eastern Europe, and Asia (Parker, 2009). The target-site herbicide-resistance is based on a modification of the enzyme in such a way that it binds to its normal substrate in the amino acid biosynthesis pathway but not to the herbicide. broomrape and bursage relationship - theluxxorgroup.com (2015). 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).

Plant Cell Physiol. 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. 103, 423431.

Nitrogen and carbon relationships between the parasitic weed Orobanche foetida and susceptible and tolerant faba bean lines. Nutrient effects on parasitism and germination of Egyptian broomrape (Orobanche aegyptiaca). Broomrape tubercles accumulate host-derived nitrogen in the form of either arginine or in the arginine and aspartate pair (Nandula et al., 2000; Abbes et al., 2009). 50, 69556958. Once ground has been infested, crop options for the field are extremely limited for a long period of time. Processing tomato growers are struggling to contain a potentially devastating parasitic weed that had not been seen since growers waged a successful eradication campaign four decades ago. 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. Sieve elements of both organisms are already interconnected by interspecific sieve pores at early stages of parasitism. Tomilov, A., Tomilova, N., Shin, D. H., Jamison, D., Torres, M., Reagan, R., et al. Crop Prot. 25, 803813. In addition to this direct effect, ethylene-producing bacteria such as Pseudomonas syringae pv. Certain amino acids strongly inhibit the early development of broomrape without phytotoxic effects in the host (Vurro et al., 2006). 23, 407413. Plant Physiol. This paper reviews relevant facts about the biology of broomrape weeds, the key mechanisms they employ to attack crops and the control methods already developed or in development that directly target those mechanisms. 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).

Thermoinhibition uncovers a role for strigolactones in Arabidopsis seed germination. 89, 177181. We are trying to hedge our bets, in terms of registering something we can use on tomatoes.. J. Pest Manag. For example, soil application of uniconazole, a triazole that is commercially used for growth regulation has proved to reduce parasitism by inhibiting seed conditioning and subsequent germination (Joel, 2000; Zehhar et al., 2002; Song et al., 2005; Lechat et al., 2012). Solarization, a physical control method for weeds and parasitic plants (Orobanche spp.) 42, 464469. Structure and function of natural and synthetic signaling molecules in parasitic weed germination. Plants (Basel). 27, 653659. 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. Soil herbigation (saturating the soil with herbicides such as sulfonylureas) effectively controls preattached stages of broomrapes (Hershenhorn et al., 2009) but is hardly compatible with other agricultural cropping practices as detrimental for many crop seedlings for several weeks or months. J. Agric. MF-A wrote the paper. Broomrape seed has been documented to last in the soil for at least 35 years.. 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). Unfortunately this technique represents another example of highly promising broomrape control strategy that has never been validated in field experiments. Branched broomrape has recently been detected in isolated fields in Yolo, Solano and San Joaquin counties, but the processing tomato business has a history of investing in efforts to eradicate this potentially disastrous weed. Host specificity in broomrape species is usually indirectly related to the predictability of nutritive resources. The physiology and biochemistry of parasitic angiosperms. The capacity of P. orobanchia to reduce broomrape populations is limited by cultural practices and antagonists (Klein and Kroschel, 2002; Aly, 2007). It is well-established in autotrophic plants that abscisic acid (ABA) acts as a positive regulator of induction of seed dormancy and its maintenance and gibberelins (GAs) antagonizes with ABA, promoting dormancy release and subsequent germination (Finch-Savage and Leubner-Metzger, 2006). 44, 22212229. (2002). Nitrogen deficiency as well as phosphorus deficiency in sorghum promotes the production and exudation of 5-deoxystrigol, the host recognition signal for arbuscular mycorrhizal fungi and root parasites. The stimulatory capability of crop root exudates is defined by the qualitative and quantitative content of germination-inducing factors and varies across crop species and cultivars. update on breeding for resistance to sunflower broomrape / actualizacin de la situacin de la mejora gentica de girasol para resistencia al jopo June 2014 Helia 33(52):1-12 doi: 10.1007/BF02980855, Prez-de-Luque, A., Moreno, M.

Plant Physiol. (1993). Crop Prot. 30, 533591. (2009). 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). Effect of triiodobenzoic acid on broomrape (Orobanche ramosa) infection and development in tomato plants. Besides arginine and aspartate, other major forms of amino acids translocate from the host phloem but they are rapidly utilized by broomrape.
