The long-term approach to parasitic weeds control: manipulation of specific developmental mechanisms of the parasite. The capacity of P. orobanchia to reduce broomrape populations is limited by cultural practices and antagonists (Klein and Kroschel, 2002; Aly, 2007). Long term dry preservation of active mycelia of two mycoherbicidal organisms. Mitochondrial DNA suggests at least 11 origins of parasitism in angiosperms and reveals genomic chimerism in parasitic plants. Group 6, 1119. 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). doi: 10.1007/s10535-007-0084-y, Vurro, M., Boari, A., Evidente, A., Andolfi, A., and Zermane, N.

Planta 227, 125132. Many of the plants now included in this family were, until recently, considered to be members of the family Scrophulariaceae. Plants (Basel). 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). 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. 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).

Takeuchi, Y., Omigawa, Y., Ogasawara, M., Yoneyama, K., Konnai, M., and Worsham, A. D. (1995). Weed Res. Target-site resistances have been successfully developed in crops either by classical breeding such as sunflower, by screening mutagenized crop populations such as the case of oilseed rape or by transgenic techniques such as tomato, tobacco, carrots, and oilseed rape (Joel et al., 1995; Aviv et al., 2002; Slavov et al., 2005; Tan et al., 2005). Nitrogen reduces branched broomrape (Orobanche ramosa) seed germination. Phainopepla - the mistletoe bird. 50, 277279. Additional mechanisms that could contribute to the selective action of host-derived strigolactones in broomrape germination could be (1) variations of molecular structure between host-derived and parasite-encoded strigolactones conferring different specificity for different biological functions or (2) different spatial localization inside the broomrape seed for functions of strigolactone detection and strigolactone synthesis (Das et al., 2015).

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).

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). (Berner et al., 1999; Ahonsi et al., 2003), a close relative of broomrapes, however, broomrape germination is not responsive to ethylene (Joel, 2000). A swelling of the host root at the penetration point is also observed due the parasitic stimulation of host tissue proliferation; (G) tubercle develops a crown of adventicious roots; (H) tubercle differentiates apical shoot meristem (single shoot meristem for Orobanche species and several shoot meristems for Phelipanche species); (I) the underground shoot eventually emerges through the root surface; (J) flowering and pollination occur.

Once in the parasite system, sucrose is not accumulated but metabolized to other compounds. Semagenesis and the parasitic angiosperm Striga asiatica. Lack of knowledge in the molecular regulation of the host-parasite interaction during crop invasion has impeded the development of varieties carrying transgenes with capacity to inhibit broomrape penetration. Sources of natural resistance based on low exudation of germination-inducing factors exist in legumes and sunflower and are highly effective in inhibiting broomrape weed parasitism (Labrousse et al., 2001, 2004; Rubiales et al., 2003b, 2009a; Prez-de-Luque et al., 2005; Sillero et al., 2005; Abbes et al., 2010; Fernndez-Aparicio et al., 2012b, 2014). 4 - Iowa State University check engine light on and off Serotinous species in North American deserts have evolved similar seed retention syndromes as .

The first function of haustorium is as adhesion organ to host root surface mediated by a papillae cell layer; (E) adhesion to the root 3 days after germination induction; (F) upon vascular connection with the host, broomape initiates the development of the tubercle, the broomrape storage organ for host-derived nutrients.

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.

Sucrose is also metabolized to starch that is accumulated in the broomrape storage organ, the tubercle (Abbes et al., 2009; Draie et al., 2011). Striga resistance in the wild relatives of sorghum. Depending on the genetic background of the resistant host, the intrusive cells of broomrape seedling can be stopped at three different levels in their way of penetration through the root layers to achieve connection with the host vascular system. Natural pesticides derived of microbial and plant origin are considered to be less harmful because they usually biodegrade quicker, resulting in less pollution-related problems. More than 40 insect herbivores from 22 families have been collected on broomrape plants but a majority of them are polyphagous without any specificity for broomrape species being some of them serious pests of important crops (Klein and Kroschel, 2002). Ann. Kusumoto, D., Goldwasser, Y., Xie, X., Yoneyama, K., and Takeuchi, Y. Dev. 5, 99108. A multiple-pathogen strategy in which two or more pathogens are combined has been proved successful for the control of broomrape causing a synergistic effect that can lead to 100% broomrape control (Dor and Hershenhorn, 2003; Mller-Stver et al., 2005). Biological control of broomrape is based on the use of living organisms either by killing seed bank or interfering with its host-recognition ability. Annu. Induction of phenolic compounds in pea (Pisum sativum L.) inoculated by Rhizobium leguminosarum and infected with Orobanche crenata.

Sauerborn (1991) estimated that 16 million ha in Mediterranean and West Asia regions risked being infested. 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).

Parasite population Broomrape seeds were originally collected in Serbia from sunflower hybrids known to be resistant to race E. This broomrape population was designated as LP12BSR and was used in a previous study as . 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. 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. inducers of ISR (Gozzo, 2003) and commercially available as Proradix can reduce broomrape parasitism by 80% in susceptible cultivars of hemp and tobacco without phytotoxic effect on the crop (Gonsior et al., 2004).

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). doi: 10.1093/pcp/pcr176.
