“…Necrosis of O. crenata tubercles was high in accessions BG01043 and BG23560. No necrosis of host cells surrounding the contact point of the parasite's radicle was observed, as previously reported in V. artropurpurea infected by O. aegyptiaca (Goldwasser et al 2000) or in chickpea and faba bean infected by O. crenata (Rubiales et al 2003;Pérez-de-Luque et al 2007). What we observed was necrosis and subsequent death of formed tubercles.…”

Field, pots and mini-rhizotrons experiments revealed the existence of useful levels of avoidance and resistance to Orobanche crenata Forsk. within Lathyrus cicera L. accessions, in addition to escape due to precocity or to reduced root biomass. This resistance was characterized by several phenotypic mechanisms of defence which acted alone or in combination, including low stimulation of parasitic seed germination, prevention of the radicle penetration inside the root and prevention of a correct connection by the parasite with the host vascular tissue being visible by reduced development of established parasitic tubercles or abortion of the parasitic tubercles formed.

“…At this stage, different constitutive or induced host resistance mechanisms such as lignification or hypersensitive-like reactions (Goldwasser et al 2000;Rubiales et al 2003;Pérez-de-Luque et al 2007) may take place. Necrosis of O. crenata tubercles was high in accessions BG01043 and BG23560.…”

“…This finding is in line with several reports associating resistance to parasitic plants with accumulation of substances at the host-parasite interface. Resistance response of Vicia atropurpurea to Orobanche aegyptiaca has been associated with accumulation of unidentified material secreted at the host-parasite interface (Goldwasser et al, 2000). Accumulations of cellulose in xylem vessels and of electron-dense materials have been reported in the Striga-resistant sorghum ''IS-777'' (Oliver et al, 1991).…”

Medicago truncatula as a Model for Nonhost Resistance in Legume-Parasitic Plant Interactions

et al. 2007

Crenate broomrape (Orobanche crenata) is a root parasitic weed that represents a major constraint for grain legume production in Mediterranean and West Asian countries. Medicago truncatula has emerged as an important model plant species for structural and functional genomics. The close phylogenic relationship of M. truncatula with crop legumes increases its value as a resource for understanding resistance against Orobanche spp. Different cytological methods were used to study the mechanisms of resistance against crenate broomrape of two accessions of M. truncatula, showing early and late acting resistance. In the early resistance accession (SA27774) we found that the parasite died before a tubercle had formed. In the late resistance accession (SA4327) the parasite became attached without apparent problems to the host roots but most of the established tubercles turned dark and died before emergence. The results suggest that there are defensive mechanisms acting in both accessions but with a time gap that is crucial for a higher success avoiding parasite infection.Crenate broomrape (Orobanche crenata) is one of the most important parasitic plants attacking legume crops in Mediterranean area, devastating crops and making unusable infested land (Rubiales, 2001(Rubiales, , 2003Rubiales et al., 2002). Being a broomrape (Orobanche sp.), crenate broomrape is an obligate root holoparasite lacking in chlorophyll and depending entirely on the host for its supply of nutrients (Joel et al., 2007). The knowledge of the mechanisms of resistance against the parasite is crucial to develop strategies of control, like breeding for resistance. With this purpose, we have chosen Medicago truncatula as a crenate broomrape host model plant due to its characteristics.M. truncatula is an annual forage legume in the Mediterranean area. Contrary to other legume crops, M. truncatula is an autogamous self-fertile plant with a small and diploid genome, a short life cycle, and a prolific seed production (Blondon et al., 1994). Its simple genetics, the development of new tools and methods for molecular and genetic analysis, and the complete genome sequence (http://www.medicago.org) provide researchers with a valuable data set and making it interesting as a legume model species for laboratory studies (Cook et al., 1997;Cook, 1999) and also in pathogenic interactions (Ellwood et al., 2007; Pérez-de-Luque et al., 2007a).Nowadays, the most numerous and important works about parasitic plants were focused on the development in susceptible host, as Orobanche spp. (Joel and Losner-Goshen, 1994;Neumann et al., 1999), Striga spp. (Dörr, 1997;Reiss and Bailey, 1998), Cuscuta spp. (Vaughn, 2002(Vaughn, , 2003, Viscum spp. (Heide-Jørgensen, 1987), and others (Heide-Jørgensen and Kuijt, 1993, 1995). But little is known about the basis of host resistance to these parasites, just finding the work of Joel et al. (1996) introducing this subject. In the last years only some histological studies of the resistant interactions have been undertaken (Dörr et al., 199...
