In this regard, France is doing valuable work through the Technical Center for Oilseed Crops and Industrial Hemp, Terresinovia, where a nationwide survey of infested fields is actualized online on real time by the farmers with new cases emerging every year and recently toward new regions such as the French Centre region1 Several studies suggest that large areas of new territory are at risk of invasion by broomrape (Mohamed et al., 2006; Grenz and Sauerborn, 2007), and in fact, invasions in completely new regions are already emerging in countries such as Spain, UK, France, Algeria, Ethiopia, Egypt, Sudan (Reda, 2006; Babiker et al., 2007; Babiker, 2008; Rubiales et al., 2008; Abu-Irmaileh and Labrada, 2009; Parker, 2014). Once a field is infested, controlling the broomrape seed bank is very difficult due to its high resilience. Biocontrol Sci.

(2001). Those interactions promote the broomrape seed bank remains dormant inhibiting the initiation of broomrape parasitism, and therefore its rates of seed bank replenishment. seed germination. doi: 10.1046/j.1365-313x.2001.00971.x, Mauro, R.

This treatment in the lab mimics the soil conditions in climatically suitable regions for broomrape such as Mediterranean non-irrigated agrosystems where the onset of warm and wet season coincides with the growth of juvenile stages of many annual crops (Lpez-Granados and Garca-Torres, 1996; Grenz and Sauerborn, 2007). Plant Growth Regul. 4, 25702575. 49(Suppl.

Rev. The inductor potential of root exudates from a given species varies with the broomrape considered.

Transfer of organic substances from the host plant Vicia faba to the parasite Orobanche crenata Forsk. 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). Metzger, J. Bot. 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).

This gene remains silenced during conditioning phase and its activation occurs mediated by host-encoded germination stimulants, i.e., strigolactones, only after the conditioning phase is complete. broomrape and bursage relationship - 1atlanticfunding.com 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. 60, 641650. doi: 10.2478/jppr-2014-0023, Hearne, S.

When resistant crops impose barriers to stop the parasitic development at this stage, broomrape exhausts and parasitism is quickly aborted. (2007). 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). The best studied group of germination-inducing factors are strigolactones, a group of terpenoid lactones. Infection of chickpea (Cicer arietinum) by crenate broomrape (Orobanche crenata) as influenced by sowing date and weather conditions. It allows the parasite to quickly start tapping carbohydrates, amino acids, and organic acids from its host (Drr and Kollmann, 1995; Nandula et al., 2000; Abbes et al., 2009). doi: 10.1021/jf030025s, Grenz, J.

(2015). Role of the sucrose synthase encoding PrSus1 gene in the development of the parasitic plant Phelipanche ramosa L. (Pomel). 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). 65, 453459. 7:135. doi: 10.3389/fpls.2016.00135. J. Exp. Methods for Orobanche and Phelipanche spp. This is a short and delicate stage where the parasite either connects with the host or dies due to nutrient exhaustion. 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. The use, distribution or reproduction in other forums is permitted, provided the original author(s) or licensor are credited and that the original publication in this journal is cited, in accordance with accepted academic practice. Acquisition of water is driven by a lower water potential in broomrape tissues (Ehleringer and Marshall, 1995). The long-term approach to parasitic weeds control: manipulation of specific developmental mechanisms of the parasite. 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. doi: 10.1002/adfm.201300053, Fernndez-Aparicio, M., Andolfi, A., Evidente, A., Prez-de-Luque, A., and Rubiales, D.

This is how can we live with this without huge yield losses. A continuous phloem system between broomrape and its host has been microscopically observed at the terminal haustoria. Seed Sci. Parasitic plants Striga and Phelipanche dependent upon exogenous strigolactones for germination have retained genes for strigolactone biosynthesis. Longevity of crenate broomrape (Orobanche crenata) seed under soil and laboratory conditions. 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. Underground Mechanisms of Parasitism and Associated Strategies for their Control: A Review. 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. 2021 Dec;37(6):512-520. doi: 10.5423/PPJ.OA.04.2021.0066. Intercropping systems cultivate simultaneously more than one species in close association to take agronomic advantage of biodiversity, competition, and complementarity between them. 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. Comparative transcriptome analyses reveal core parasitism genes and suggest gene duplication and repurposing as sources of structural novelty. Biol. Once broomrape has established connection with the vascular system of its hosts, broomrape management should be performed quickly to abort at earlier stages the strong parasitic sink for nutrients and water. doi: 10.1016/j.cropro.2010.03.004, Fernndez-Aparicio, M., Garca-Garrido, J.

This spatial/temporal frame defines the maximum host-reaching distance for successful broomrape parasitism. 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). Technologies for smart chemical control of broomrape (Orobanche spp.
