“…Other bacterial isolates (Stenotrophomonas maltophilia QUBC61, and unidentified isolates QUBC67, and QUBC68) showed no significant inhibition of radical elongation. Zermane, Souissi, Kroschel, and Sikora (2007) have shown that P. fluorescens Bf7-9 can suppress the pre-emergence of O. foetida Poir. and O. crenata when tested in pot experiments.…”

The ability of different bacteria to inhibit Orobanche radical elongation was examined. Seeds of Orobanche aegyptiaca Pers. and O. cernua Loefl. were induced to germinate with the Growth Regulator GR24 in the presence or absence of test bacterium. Radical lengths were estimated microscopically on a scale relative to seed length (0Á5 seed lengths) after 5 days of incubation at 258C. The results indicated that Pseudomonas aeruginosa QUBC1, P. fluorescens QUBC3, Bacillus atrophaeus QUBC16, and B. subtilis QUBC18 significantly inhibited radical elongation (P50.01) of both O. aegyptiaca and O. cernua relative to control radicals, whereas Microbacterium hydrocarbonoxydans QUBC11 and Ochrobactrum anthropi QUBC13 showed less inhibitory effects. Other bacterial isolates had no inhibitory effects. Bacterial isolates were identified using the universal method in addition to morphological and biochemical features. The establishment of the inhibitory effect of the most promising isolates, B. atrophaeus QUBC16 and P. aeruginosa QUBC1 on radical elongation of both Orobanche spp. is a step towards utilizing such bacteria as biocontrol agents against O. aegyptiaca, O. cernua, and potentially other Orobanche species.

“…Endophytic bacteria may also contribute resistance to their hosts by suppressing pathogens and enhancing the plant’s immune system (Azevedo et al, 2000; Rosenblueth and Martínez-Romero, 2006; Ryan et al, 2008; East, 2013). Furthermore, as recently reviewed by Joel et al (2013), plant endophytes may influence the interaction of their hosts with parasitic weeds, For example the bacterium Azospirillum brasilense inhibits seed germination and radical elongation in the broomrape P. aegyptiaca ; Pseudomonas fluorescens reduces both the quantity and biomass of the broomrape Orobanche foetida (Zermane et al, 2007); and the bacterium Rhizobium spp. reduces not only seed germination of O. foetida but also the number of tubercles on its host’s (chickpea) roots (Hemissi et al, 2013).…”

Host-Parasite-Bacteria Triangle: The Microbiome of the Parasitic Weed Phelipanche aegyptiaca and Tomato-Solanum lycopersicum (Mill.) as a Host

Broomrapes (Phelipanche/Orobanche spp.) are holoparasitic plants that subsist on the roots of a variety of agricultural crops, establishing direct connections with the host vascular system. This connection allows for the exchange of various substances and a possible exchange of endophytic microorganisms that inhabit the internal tissues of both plants. To shed some light on bacterial interactions occurring between the parasitic Phelipanche aegyptiaca and its host tomato, we characterized the endophytic composition in the parasite during the parasitization process and ascertained if these changes were accompanied by changes to endophytes in the host root. Endophyte communities of the parasitic weed were significantly different from that of the non-parasitized tomato root but no significant differences were observed between the parasite and its host after parasitization, suggesting the occurrence of bacterial exchange between these two plants. Moreover, the P. aegyptiaca endophytic community composition showed a clear shift from gram negative to gram-positive bacteria at different developmental stages of the parasite life cycle. To examine possible functions of the endophytic bacteria in both the host and the parasite plants, a number of unique bacterial candidates were isolated and characterized. Results showed that a Pseudomonas strain PhelS10, originating from the tomato roots, suppressed approximately 80% of P. aegyptiaca seed germination and significantly reduced P. aegyptiaca parasitism. The information gleaned in the present study regarding the endophytic microbial communities in this unique ecological system of two plants connected by their vascular system, highlights the potential of exploiting alternative environmentally friendly approaches for parasitic weed control.

“…Extensive information on signals from different of sources, including microorganisms, and their effect on the parasitic species can be found (Umehara et al, 2008). About chemical inducers, plant inducers, microbial inducers leading to suicidal germination of the parasite in the absence of host (Christeva et al, 1998;Lachia et al, 2014); about inhibitors of the germination process (Zermane et al, 2007;Chen et al, 2016); about microbial toxins (Andolfi et al, 2005;Vurro et al, 2009;Louarn, 2011;Sun, 2011) (Werner, 2001;Allison et al, 2007). In this regard, the participation of soil microorganisms in ongoing processes in the rhizosphere at plants infected by broomrapes is not well defined.…”

“…The relationships in plant systems: host / broomrape are extremely complex and specific. Multitude diverse factors (abiotic and biotic) have influence on them (Wegmann, 1986 (Andolfi et al, 2005;Sauerborn J. et al, 2007;Zermane et al, 2007;Sun, 2011). Considerable progress has been registered in the field of arbuscular mycorrhizal fungi (AMF) research in connection with relationships in the parasitic system and also potential for use them about biological control.…”
