In addition it promotes the development of a layer of papillae at the radicle apex in the absence of host contact, morphology that resembles the attachment organ (Joel and Losner-Goshen, 1994; Cimmino et al., 2015). 6, 31293140. Synthetic analogs of growth regulators can be successfully used to reduce parasitism by hampering the synchronization of the parasitic seed bank with the growth of the host. Hanson and fellow researchers UC Davis assistant professor Mohsen Mesgaran and graduate student Matthew Fatino discussed their progress toward a management strategy during the 63rd annual Weed Day on the Davis campus. 31, 2730. doi: 10.1016/j.cropro.2006.10.012, Fernndez-Aparicio, M., Yoneyama, K., and Rubiales, D.

Several factors contribute to the fact that broomrape weeds remain an uncontrolled agricultural problem. Pectolytic activity by the haustorium of the parasitic plant Orobanche L. (Orobanchaceae) in host roots. Annu. As a consequence the crop is protected from broomrape invasion (Joel and Portnoy, 1998; Westwood et al., 1998; Hamamouch et al., 2005; Aly et al., 2006). Crop Prot. If this works, it will be easy to implement through the fertilizer system.. Besides the effects of fertilization management on pre-attached broomrape stages described in previous sections, high soil fertility can induce crops to endure broomrape parasitism by helping the host to maintain a favorable osmotic potential that reduces the parasitic sink strength (Gworgwor and Weber, 1991).

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. GA acts positively on germination in dormant non-parasitic species by counteracting ABA (Seo et al., 2009). In general, parasitized crops suffer from reductions in total biomass at the greatest expense to the reproductive tissue (Barker et al., 1996; Manschadi et al., 1996; Lins et al., 2007). 93, 300313. Mol. The insect herbivore as a predictive model in parasitic seed plant biology. Plant Physiol. The model was developed in greenhouse studies and validated in the field during three growing seasons. We reviewed relevant facts about the biology and physiology of broomrape weeds and the major feasible control strategies.

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). 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). 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). (1995). The effectiveness of amino acids as broomrape inhibitors has not been proved in real field conditions but field application of amino acids has been effective to manage other parasites such as plant-parasitic nematodes (Zhang et al., 2010). 21, 5561. doi: 10.1007/s11248-004-8081-9, Song, W.

Despite of this fact, Seed Certification Services in some of the countries affected, do not include in their certification standards, inspection of crop seed samples for broomrape inoculum. 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. However, selecting for high phenolic varieties is likely to induce many other side changes altering agronomic performance. doi: 10.1006/anbo.1997.0563, Louarn, J., Carbonne, F., Delavault, P., Becard, G., and Rochange, S.

Based on those conditions, methionine has the potential to be used as broomrape herbicide but it needs to be confirmed and its application adjusted to real field conditions. This parasitic weed, unable to produce its own chlorophyll, survives only by attaching to the roots of a host plant, often with severe consequences. Still, as the parasite is synchronized on the crop development this means in some cases that the change disfavoring the parasite could also limit the maximum potential yield for the crop. J. Exp.

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). Multiple flushes (cohorts) of emergence could be found within a single season . 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. (2013). The release of phytochemicals by the roots of the allelopathic component in the intercrop inhibits the broomrape germination and/or radicle elongation toward the host component. Although analytical chemistry methods have failed to detect strigolactones in parasitic plants (Liu et al., 2014), transcriptome sequencing reveals that all known strigolactone genes, both synthesis and perception are present in broomrapes with apparently full-length proteins (Pron et al., 2012; Das et al., 2015).

The Problem of Orobanche spp. The terminal haustorium develops at the apex of the seedling radicle upon host recognition (Musselman, 1980; Joel and Losner-Goshen, 1994). 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). Biocontrol Sci. (2002). Plant Microbe Interact. 69, 463472. Egyptian broomrape (Phelipanche aegyptiaca) response to silicon nutrition in tomato (Solanum . 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).

C., Seryes, H., Berville, A., and Thalouarn, P. (2001). Therefore an integrated and sustained management strategy composed by several control methods acting at different broomrape life stages is highly recommended to keep away the broomrape weed problem in a durable manner (Kebreab and Murdoch, 2001). broomrape and bursage relationship - 1atlanticfunding.com (2007). They are quite noticeable in the desert, as males like to perch at the very top of mesquite trees (like the one above). Acquisition of water is driven by a lower water potential in broomrape tissues (Ehleringer and Marshall, 1995). Plant Physiol. Using biotechnological approaches to develop crop resistance to root parasitic weeds. 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). The development of the solutions has usually not been conducted to their end so that many potential ways of controlling broomrape are not on the market.
