Plant Microbe Interact. Mller-Stver, D. (2001). Mater. Weed Res. The predictability of establishment on perennial hosts is high and therefore wild broomrape species feeding off perennial plants have narrow host ranges. (2009). This kind of resistance is more interesting than other mechanisms of resistance that usually involve translocation and enhanced metabolism, resulting in lower herbicide concentration in the sap of the host plant. doi: 10.1104/pp.119.2.585, Aly, R.

Positive regulation: (1) production by each flower scape of hundreds of thousands of seeds able to survive in the soil for more than 10 years; (2) production by the host plant of strigolactones or glucosinolates that stimulate seed germination (blue arrows). (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. A better understanding of the biochemistry of host recognition in broomrape will facilitate the generation of control strategies targeting the haustorium development. This work was cofunded by the European Union and INRA, in the framework of the Marie-Curie FP7 COFUND People Program, through the award of an AgreenSkills fellowship (under grant agreement n PCOFUND-GA-2010-267196) to MF-A with additional support by the INRA Division Sant des Plantes et Environnement., Abbasher, A.

Sources of low-inducers genotypes exist in crops species attacked by the close related parasitic weed Striga (Rich et al., 2004). 60, 295306. Biomol. Broomrape seed bank remains viable in the soil for many years until germination is triggered by the coincidence of several physical and chemical factors that are indicative of environmental conditions for successful seedling establishment: i.e., the nearby growth of a host plant in a physiological stage susceptible for broomrape invasion and subsequent parasitic reproductive growth (Linke and Saxena, 1991; Lpez-Granados and Garca-Torres, 1996, 1999). Rev. Influence of nitrogen on germination and early development of broomrape (Orobanche spp.). Special interest arises from those metabolites with a favorable pattern of broomrape-specific effect (e.g., tenuazonic acid) and no described side-effect to other biosystems (Vurro et al., 2009). 8600 Rockville Pike These plants are best known by their straw-yellow stems, which are completely free of chlorophyll and have blue, white, or yellow dragon-like flowers. The chemical characteristics of the barriers of resistance to broomrape penetration have been extensively studied in Fabaceae crops (Prez-de-Luque et al., 2009) and are reviewed in this article in Section Resistant Crops to Broomrape Invasion.. Host specificity in broomrape species is usually indirectly related to the predictability of nutritive resources. doi: 10.1021/jf5027235, Fernndez-Aparicio, M., Kisugi, T., Xie, X., Rubiales, D., and Yoneyama, K. (2014). and their current disposition. The Problem of Orobanche spp. Resistance that occurs in the endodermis is mediated by lignification of endodermal and pericycle cell walls. In recent years, a new, aggressive race designated as race F (called biotype D in Russia) has . Longevity of crenate broomrape (Orobanche crenata) seed under soil and laboratory conditions. 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. 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).

Shortly after host penetration and connection, the parasite begins its heterotrophic growth at the expense of host resources. J. Exp. The timing of germination is the most crucial event that obligated parasitic plants face along their life cycle (Figure 2C). Gain of host sensitivity in broomrape seeds at the end of the conditioning phase is mediated by demethylation of PrCYP707A1 promoter.

Few days after host vascular connection, the part of the broomrape seedling that remains outside the host root develops into a storage organ called tubercle. Phytopathol. seed germination. 22, 937947. Plant Growth Regul. Even the easiest method of control, herbicides, requires broomrape specific-optimization for each cropping system to target the most vulnerable broomrape life stage, the young attachments while preserving the crop. 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).

During the host penetration process, broomrape does not dissolve the host cells in its way toward vascular cylinder. It is best recognized by its yellow-to-straw coloured stems completely lacking chlorophyll, bearing yellow, white or blue, snapdragon-like flowers. doi: 10.1111/j.1744-7348.2007.00212.x, Prez-de-Luque, A., and Rubiales, D.

Phytomyza orobanchia is reported to be broomrape-specific and its main action as biocontrol agent is by reduction of broomrape reproductive activity due to their feeding activity on ovules and young seeds. doi: 10.1039/b907026e, Boari, A., and Vurro, M. (2004). Pseudomonas aeruginosa, P. fluorescens, Bacillus atrophaeus, B. subtilis are promising biocontrol agents targeting the growth of broomrape radicles (Barghouthi and Salman, 2010). 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. Phainopepla - the mistletoe bird - Wild Mountain Echoes Joel, D. M. (2013). (1976) by using the synthetic strigolactone analog GR7. They write new content and verify and edit content received from contributors. The requirement for germination-inducing factors in order to break dormancy in parasitic seeds are bypassed by ethylene or cytokinins (which promotes ethylene biosynthesis) in Striga sp. 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. doi: 10.1111/j.1365-313X.2007.03171.x, Klein, O., and Kroschel, J. doi: 10.1111/j.1399-3054.1993.tb01802.x, Slavov, S., Valkov, V., Batchvarova, R., Atanassova, S., Alexandrova, M., and Atanassov, A. Systemic translocation of nanoencapsulated herbicides could improve this herbicidal approach (Prez-de-Luque and Rubiales, 2009). The taxonomy of the group is somewhat contentious, and the American species of broomrape are sometimes placed in the genus Aphyllon. Control 2 291296. Weed Res. In this process, cellular expansion of the root meristem is redirected from longitudinal to radial and the root apex changes its form from conical to spherical. Figure 1. Plant Mol. Use of other soil sterilants such as metham sodium, dazomet, and 1,3-dichloropropene have shown different degrees of efficacy but their high cost, complex application and negative environmental effects have prevented their widespread use by farmers (Foy et al., 1989; Goldwasser et al., 1995; Hershenhorn et al., 2009) or conducted to the withdrawal of authorization, at least in some countries. Weed Res. The .gov means its official. Musselman, L. J. doi: 10.1093/molbev/msu343, Yoder, J. I., and Scholes, J. D. (2010). This effect may not be applicable to those broomrape species with preference for classes of germination-inducing factors other than strigolactones (Joel et al., 2011; Auger et al., 2012). Due to their achlorophyllous nature, broomrapes are constrained to obtain their nutritional resources by feeding off other plants using the haustorium, an organ unique in parasitic plants through which the parasite diverts water and nutrients from the host (De Candolle, 1813; Kuijt, 1969; Musselman and Dickison, 1975; Westwood, 2013). doi: 10.1093/aob/mcm032, Ben-Hod, G., Losner-Goshen, D., Joel, D.

It remains unknown whether host factors are required by broomrape radicle to initiate haustorium and consequently this strategy has not been fully explored. 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: 10.1016/j.agee.2007.01.014, Gressel, J. Nature 374, 220221. Biocontrol Sci. (2012). 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).

Many beneficial organisms are either able to survive the solarization treatment or able to recolonize solarized soil (Sauerborn et al., 1989; Mauromicale et al., 2001). -. This would open the work on parasitism toward more community ecology and what can be considered the realistic nature of parasitism. Plant Mol. (2006). Until now, difficulties of purification at industrial scale have hampered the field experimentation with such metabolites (Vurro et al., 2009) despite their interesting potential. Evaluation of Fusarium spp. (1997). Broomrape Eradication is High Priority for UC Researchers, 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, The host range of broomrape, in addition to tomato, covers a number of economically important rotational crops in the Central Valley: safflower, sunflower, carrot, bell pepper, several, Hanson and fellow researchers UC Davis assistant professor, Vergara presents findings on farmer-to-farmer education in Panama, Melotto named AAAS fellow for work in plant defenses against bacteria, Yasay accident report released by Davis Police, Poudel wins AAUW International Fellowship, Our leadership-Plant Sciences Executive Committee, Guidelines for Departmental GSR Annual Progress Report and Final Report, Plant Sciences Graduate Student Travel Award, Plant Sciences Teaching Assistantship (TA) Application (temporary link).
