Diverse Host Spectrum and the Parasitic Process in the Pantropical Hemiparasite <i>Cassytha filiformis</i> L. (Lauraceae) in China
Many hemiparasites attach to a range of different host species, resulting in complex parasite–host interactions. Comprehensive molecular phylogenies allow the investigation of evolutionary relationships between these host plants. We surveyed the hosts of the laurel dodder (<i>Cassytha filiform...

| description | Many hemiparasites attach to a range of different host species, resulting in complex parasite–host interactions. Comprehensive molecular phylogenies allow the investigation of evolutionary relationships between these host plants. We surveyed the hosts of the laurel dodder (<i>Cassytha filiformis</i>, Lauraceae) in China, representing 184 species from 146 genera, 67 families, and spanning flowering plants, conifers, and ferns, using host phylogenetic relationships to investigate the susceptibility to attack by this hemiparasitic plant among the vascular plants. The process of produced well-formed haustoria by <i>C. filiformis</i> was also observed in detail for six different hosts. Our results show that <i>C. filiformis</i> grows mainly on trees and shrubs from phylogenetically divergent members of the rosid and asterid eudicot clades, often attacking multiple adjacent hosts simultaneously, and forming extensive colonies. However, whether and to what extent transitions between <i>C. filiformis</i> and host plants occur remain unclear. Physiological evidence for the complex parasite–host species interactions need to be studied in the future. |
