Phylogenomics of Western Eurasian Tilia: merging GBS datasets to place the Hyrcanian forest limes.

ABSTRACT:

Background

Morphological uniformity in Tilia (Malvaceae s.l., Tilioideae) and unclear species delimitations resulted in over 500 names associated with the about 30 species of this genus. This is also an issue for the Hyrcanian Forest diversity hotspot of northern Iran, where between one and seven Tilia species were described to occur. We used genotyping-by-sequencing (GBS) to analyze the phylogeny of western Eurasian Tilia species, place the Hyrcanian Tilia populations, and infer their phylogeography. To arrive at a complete taxon sample, we merged our own data (104 samples) with a Tilia GBS dataset available in GenBank (11 samples) and processed and analyzed them together.

Results

We confirmed GBS data to be additive, i.e. independent datasets can be merged. We found three
