Genetic admixture and novel host shifts in a parasitic plant, Orobanche boninsimae (Orobanchaceae), endemic to the Ogasawara Islands

Parasitic plants depend on other plants for nutrients and water and have undergone evolutionary processes tightly linked to their host range. As parasitic adaptations specialize host range, host shifts between parasite lineages are considered essential events that can lead to genetic differentiation and speciation. A thorough examination of population genealogy covering the entire host range is imperative to comprehend the impact of host-shift evolution on parasitic plant species diversity. Therefore, we investigated the population genetic structure of Orobanche boninsimae (Orobanchaceae), an endemic parasitic plant in the Bonin (Ogasawara) Islands. The host species of O. boninsimae are entirely distinct from those of other Orobanche species and show differences between geographically isolated islands, even though the host species coexist in some localities. Genetic differentiation was observed among populations from different islands, corresponding to variations in the host range of O...., , , # Data from: Genetic admixture and novel host shifts in a parasitic plant, Orobanche boninsimae (Orobanchaceae), endemic to the Ogasawara Islands
