Phylogenomics of the Andean tetraploid clade of the American Amaryllidaceae (subfamily Amaryllidioideae)

dataset
posted on 2024-01-26, 23:55 authored by USDA-ARS
The second large clade of the endemic American Amaryllidaceae subfam. Amaryllidoideae constitutes the tetraploid-derived (n = 23) Andean-centered tribes, most of which have 46 chromosomes. Despite progress in resolving phylogenetic relationships of the group with nrDNA, certain subclades were poorly resolved or weakly supported in those previous studies. Sequence capture using anchored hybrid enrichment was employed across 95 species of the clade along with five outgroups and generated sequences of 524 nuclear genes and a partial plastome. Maximum likelihood phylogenetic analyses were conducted on concatenated supermatrices, and coalescent species tree analyses were run on the gene trees, followed by hybridization network, age diversification and biogeographic analyses.
