The first attempts to deplete parasitic weed seed bank was made by Johnson et al. 93, 300313. Post-germination development in broomrape could be probably regulated by their own broomrape-encoded strigolactones as it occurs in the close related parasite Striga hermonthica or in non-parasitic plants (Liu et al., 2014; Das et al., 2015). Tempting as it may be to keep an infestation secret, the consequences of risking spread of broomrape could be disastrous. Biological control of broomrape is based on the use of living organisms either by killing seed bank or interfering with its host-recognition ability. How broomrapes make the distinction not only between host-derived and their own-encoded strigolactones but also how they sense diversified strigolactone profiles in root exudates across species correlated with host ranges.

In addition long lived seed banks under physiological dormancy ensure that germination will occur when a suitable host in its correct stage of development is present nearby (Rubiales et al., 2009b).

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). 51, 702707.

How Striga parasitizes its host: a TEM and SEM study.

The re-emergence of branched broomrape in California is of concern to the processing tomato industry as: 1) the experience in other regions of the world has demonstrated the extreme vulnerability of tomato to branched broomrape parasitism, 2) broomrapes seem likely to rapidly establish and spread in California because of the similarity to the species' native climate, (3) repeated cultivation . doi: 10.1007/s00425-011-1568-8, Yoneyama, K., Xie, X., Kusumoto, D., Sekimoto, H., Sugimoto, Y., Takeuchi, Y., et al. doi: 10.1007/s11627-007-9054-5, Aly, R., Plakhin, D., and Achdari, G.

Broomrape seeds are less capable to recognize crop roots colonized by arbuscular mycorrhizal fungi, Rhizobium leguminosarum or Azospirillum brasilense due to change in the composition of the root exudates in colonized plants (Dadon et al., 2004; Mabrouk et al., 2007a; Fernndez-Aparicio et al., 2009c, 2010b; Louarn et al., 2012).

(Orobanchaceae) induces expression of a pathogenesis related (PR) gene in susceptible tobacco roots. If left uncontrolled during one or a few seasons, broomrape weeds build a hardly destructible seed bank in agricultural soils that further renovates at a rate of millions of seeds per ha each year a susceptible crop is infested. 72, 564574. 38, 343349.

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). Successful reduction of broomrape parasitism in the current crop is obtained by intercropping host species with inhibitory species of cereals, fenugreek, or berseem clover (Fernndez-Aparicio et al., 2007, 2008b, 2010a). J. According with pot experiments carried out in the tomato-P. aegyptiaca system, deep-plowing bringing the seeds to depth 12 cm will strongly reduce broomrape infection severity in terms of number of parasites, total parasitic biomass, delayed broomrape emergence and prevention of flower initiation and seed set (Eizenberg et al., 2007). The embryos in broomrapes have not morphologically identified cotyledons or shoot meristems and upon germination, only a radicle emerges through the seed coat with the only function of reaching and invading the host. 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). 20, 471478. 125, 9297.

Are pectinolytic activities of Orobanche cumana seedlings related to virulence towards sunflower? 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).
