Beechdrops ranges from New Brunswick west to Ontario and Missouri and south to the Gulf of Mexico. Convergent evolution of strigolactone perception enabled host detection in parasitic plants. Like most seeds, broomrape seeds are resistant to rapid microbial degradation due to phenols located in its testa (Cezard, 1973). 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. Second, broomrape weed exerts their damage underground right after attachment and therefore, contact herbicides applied after broomrape emergence, e.g., 2,4-D, had no effect on limiting yield loss in the current crop. 83, 453458. We reviewed relevant facts about the biology and physiology of broomrape weeds and the major feasible control strategies. The Problem of Orobanche spp. 21, 333340.

Broomrape high fecundity, with thousands of seeds released per broomrape plant (Figures 2A,B), multiplies the chances of the next generation to encounter a host and achieve successful parasitism (Parker and Riches, 1993). Intercropping systems cultivate simultaneously more than one species in close association to take agronomic advantage of biodiversity, competition, and complementarity between them. Broomrape, commonly called Orobanche, is a genus of more than 200 species of herbaceous plants native to the temperate northern hemisphere. In those cases, broomrape displays a pathogenic nature promoting disease in the crop mainly through negative effects on the crop photosynthetic machinery and hormonal balance (Stewart and Press, 1990; Mauromicale et al., 2008). Current chemical control of post-attached broomrape life stages is mainly achieved with foliar applications of systemic herbicides inhibiting ALS (imidazolinones, sulfonylureas) or EPSPS (glyphosate) to the leaves of crop varieties carrying target-site resistances to those herbicides to avoid direct injury of their metabolism.

XR and SG-L additional text, editing, and comments. 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. 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). Assessment of pathogenicity or damages toward non-target plants has to be carefully assessed in order to avoid environmental risks. J. Agric. Plant Dis. 32, 767790. Inhibition of shoot branching by new terpenoid plant hormones. Using biotechnological approaches to develop crop resistance to root parasitic weeds. The reduction of ABA:GA ratio induced by stratification (conditioning) is enough to break dormancy and promote germination in dormant seeds of non-parasitic weeds but it is not enough for broomrape, which requires a further decrease in ABA levels induced by the activation of the ABA catabolic gene PrCYP707A1 (Lechat et al., 2012). doi: 10.1080/09583150903340544, Barker, E.

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. 23, 407413. Nitrate reductase is not detectable (Lee and Stewart, 1978) and activity of glutamine synthetase is very low (McNally et al., 1983). 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. 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.. in a subterranean clover pasture. doi: 10.1111/j.1365-3180.2009.00742.x, Rubiales, D., Fernandez-Aparicio, M., and Rodriguez, M.

Phosphorous and nitrogen have been described to down regulate strigolactones exudation in some crop species (Yoneyama et al., 2007a,b, 2012). 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. Despite the reports of broomrape inefficient machinery for nitrogen assimilation and broomrape dependence for host-derived organic forms of nitrogen demonstrated by the fact that broomrape growth is arrested when feeding on host cultivars with decreased amino acid-phloem levels (Abbes et al., 2009), inhibition of enzymes at the top of amino-acid biosynthetic pathway by means of either direct inhibitory action of herbicides (Gressel, 2009) or by feedback inhibition induced by amino-acid end-products (Vurro et al., 2006) are able to kill broomrape.

Azospirillum brasilense is reported to inhibit broomrape radicle growth (Dadon et al., 2004). Evaluation of weed eradication programs: the delimitation of extent. Unfortunately this technique represents another example of highly promising broomrape control strategy that has never been validated in field experiments. Resistance against broomrapes (Orobanche and Phelipanche spp.) doi: 10.1002/ps.1739, Sarosh, B. R., Sivaramakrishnan, S., and Shetty, H. S. (2005). This strategy to abort broomrape invasion requires regulating the toxin production with promoters specifically induced around the site of Orobanche penetration such as the HMG2 promoter, ensuring correct delivery of the toxic effect to the broomrape penetrating seedling and overall low concentration of the toxin in the rhizosphere. 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. Interaction of light and hormone signals in germinating seeds. Effective broomrape control should target the underground mechanisms of crop parasitism in order to meet both the short-term productivity expectations of the farmer and reduction of soil bank in the long run (Figure 1). Several classes of germination stimulants have been identified in root exudates such as strigolactones (Xie et al., 2010), peagol and peagoldione (Evidente et al., 2009), peapolyphenols AC (Evidente et al., 2010), soyasapogenol B, trans-22-dehydrocampesterol (Evidente et al., 2011), dehydrocostus lactone (Joel et al., 2011), or isothyocyanates (Auger et al., 2012).

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. The effect of nitrogenous compounds on in vitro germination of Orobanche crenata Forsk. Root system in mature broomrape plants is reduced to short adventitious parasitic roots with functions of anchorage and stabilization in the soil and their leaves are reduced to small achlorophyllous scales (Parker and Riches, 1993).

Striga hermonthica MAX2 restores branching but not the very low fluence response in the Arabidopsis thaliana MAX2 mutant. (2005). 12, 638652. 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. It produces a large number of tiny seeds and many of them are long-lived.. Careers. Figure 2. Jan 08, 2016. And four, despite reports on broomrape inefficient machinery for nitrogen assimilation, and on amino acid fluxes from the host phloem to the parasite, herbicides inhibiting amino acid biosynthesis in the parasite via suppressive action on broomrape-encoded acetolactate synthase (ALS) and enol-pyruvylshikimate phosphate synthase (EPSPS) enzymes are able to kill broomrape.

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. (1981). In non-parasitic plants, physiological dormancy can be relieved through stratification but in the case of broomrape weeds, two consecutive processes are required to release dormancy: an environment-dependent first step of warm stratification called the conditioning phase, and a host-dependent second step of chemodetection. Fertilization can induce soil suppressiveness to initiation of broomrape parasitism. Annu. The harvest of infested fields or blocks, because of the biology of this weed and its standing as a California Department of Food and Agriculture Class A status, is extremely ill-advised., (Article by Bob Johnson, Sacramento reporter.

Were trying to get a relatively low rate of material into the crop, high enough to kill the parasitic weed but low enough to not damage the crop, Hanson said. 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). Delaying sowing date has, however, a general drawback by reducing yield potential under normal development so that plant breeding program tend generally to favor long lasting cultivars with early sowing dates. 100, 537544.
