American mistletoes: A dataset of Phoradendron species and their hosts across their distribution range.

Parasite-host systems are a good study model for answering ecological and evolutionary questions. In this regard, mistletoes have been increasingly studied in recent decades in both temperate and tropical zones. The genus Phoradendron is a group of American mistletoes that has been studied from different evolutionary and ecological approaches as a model of parasite-host systems. Currently, however, no systematic compilation of the plant species parasitized by these mistletoes is available. To address this issue, we conducted a thorough search and compilation of interactions between mistletoe species of the genus Phoradendron and their hosts. This involved consulting multiple sources, including monographs, digitized herbaria material, and scientific publications. Additionally, we incorporated information regarding the presence records of Phoradendron from the most authoritative databases at the national, continental, and global levels. This process yielded a comprehensive dataset consisting of two independent tables, offering information on the interactions and occurrences of Phoradendron throughout its distribution range in the Americas. The dataset includes the interactions between 159 mistletoe species and 118 hosts at the family level, 379 hosts at the genus level, and 544 hosts at the species level, totaling 2929 interactions between species of the genus Phoradendron and their hosts. This data paper represents an updated compilation of a genus of parasitic plants, with the purpose of making this database of interactions accessible for researchers to address questions at multiple scales and from disciplines as varied as biogeography, ecology, evolution, and epidemiology. We plan to use and expand this database with subsequent studies from the authors. There are no copyright restrictions on the dataset; please cite this data paper when using data from this publication.
