“…For instance, Artemisia campestris is practically the only host of P. arenaria (Piwowarczyk and Przemysky, 2010), Centaurea scabiosa is a host of O. elatior (Zázvorka 2010) and Orobanche ballotae A. Pujadas is strictly monophagous on Ballota hirsuta (Pujadas Salva 1997). We detected very low or no germination of non-weedy broomrapes induced by GR24.…”

Parasitic plants of genera Orobanche and Phelipanche germinate after exposition to chemical signals exuded by roots of the host plants. The most studied germination stimulants belong to strigolactones (SLs), the newly discovered plant hormones which are stimulating hyphal branching of arbuscular mycorrhizal fungi and are involved in regulation of shoot and root architecture of plants. However, little is known about the effect of strigolactones on germination of non-weedy broomrapes. The objective of our study was to investigate the sensitivity of seeds of non-weedy broomrapes to synthetic analogue of SLs, GR24.

“…Moreover, P. arenaria populations occupy usually open and relatively level areas sparsely vegetated in dry, alkaline and sandy soils on gently inclined slopes which facilitates the colonization of this group of bacteria. In addition, compared to other species of Orobanchaceae, this population in the studied area reached a small height of 8 to 20 cm [ 96 , 97 ].…”

Background Microbial communities have occasionally been observed in part of the ephemeric reproductive structure of floral stigmas, but their prevalence, phylogenetic diversity and ecological roles are understudied. This report describes the first study of bacterial and fungal communities in immature and mature stigma tissue of the endangered holoparasitic plant Phelipanche arenaria. Culture-dependent methods coupled with next-generation sequencing indicated that a small surface of the flower stigma was an unexpectedly rich and diverse microhabitat for colonization of microbial. We also compared the enzymatic activity of the bacterial communities between immature and mature stigmas samples. Results Using high-throughput sequencing methods, we identified and classified 39 to over 51 OTUs per sample for bacterial OTUs represented by Pantoea agglomerans and P. ananatis, comprising 50.6%, followed by Pseudomonas, Luteibacter spp., Sphingomonas spp. with 17% of total frequency. The bacterial profile of immature stigmas of P. arenaria contained unique microorganisms (21 of the most numerous OTUs) that were not confirmed in mature stigmas. However, the enzymatic activity of bacteria in mature stigmas of P. arenaria showed more activity than observed in immature stigmas. In the fungal profile, we recorded even 80 OTUs in mature stigmas, consisting of Capnodiales 45.03% of the total abundance with 28.27% of frequency was created by Alternaria eichhorniae (10.55%), Mycosphaerella tassiana (9.69%), and Aureobasidium pullulans (8.03%). Additionally, numerous putative plant growth-promoting bacteria, fungal pathogens and pathogen-antagonistic yeasts were also detected. Conclusions Our study uncovered that P. arenaria stigmas host diverse bacterial and fungal communities. These microorganisms are well known and have been described as beneficial for biotechnological and environmental applications (e.g., production of different enzymes and antimicrobial compounds). This research provided valuable insight into the parasitic plant–microbe interactions.

“…The species is very rare in Poland, it has so far been confirmed or reported as occurring at only four localities: in Lower Silesia (Szczęśniak 2003) and in the Niecka Nidziańska basin (Piwowarczyk and Przemyski 2010). It was recorded at one locality in the Middle Vistula Gap in the study area (Fig.…”
