“…Divergence time estimations using two different calibrations in BEAST (CAL1: using the divergence time of tribe Tulipeae according to Givnish et al, ; Figure ; see also Appendix Figure ; CAL2: using the crown age of the genus Gagea according to Kim & Kim, ; see Appendix Figure S2) were run for the ITS data. The estimated mean age of CAL2 was slightly lower and age ranges in general higher than in CAL1 (Table ).…”

“…Independent estimations of the crown and stem ages for the tribe Lilieae by Huang et al () were similar to Givnish et al (). In the recently published study of Kim and Kim (), the age estimated for tribe Tulipeae was older (39.48–66.86 Ma) in comparison to Givnish et al (), and included also an estimation for genus Gagea (23.32–43.45 Ma). We used our ITS data set (418 sequences; 107 species) as input.…”

“…The crown age of tribe Tulipeae was set to 40 Ma with a sigma factor of 2 for a calibration (CAL1), according to Givnish et al (). For CAL2, the crown age of Gagea was set to 35.5 Ma with a sigma factor of 6.5 to cover the range provided by Kim and Kim (). Convergence among chains and effective sample size of all parameters was calculated and visualized in Tracer v1.7 (Rambaut & Drummond, ).…”

“…As a consequence, it is still unclear when and where the genus and its major lineages originated. In a recent study focused on the evolution of Liliaceae, Kim and Kim () inferred an Asian origin (23.32–43.45 Ma) for Gagea , based on only a few accessions.…”

The Irano‐Turanian (IT) floristic region is considered an important center of origin for many taxa. However, there is a lack of studies dealing with typical IT genera that also occur in neighboring areas. The species‐rich monocot genus Gagea Salisb. shows a center of diversity in IT region and a distribution in adjacent regions, therefore representing a good study object to investigate spatial and temporal relationships among IT region and its neighboring areas (East Asia, Euro‐Siberia, Himalaya, and Mediterranean). We aimed at (a) testing the origin of the genus and of its major lineages in the IT region, (b) reconstructing divergence times, and (c) reconstructing colonization events. To address these problems, sequences of the ribosomal DNA internal transcribed spacer (ITS) region of 418 individuals and chloroplast intergenic spacers sequences (psbA‐trnH, trnL‐trnF) of 497 individuals, representing 116 species from all sections of the genus and nearly its entire distribution area were analyzed. Divergence times were estimated under a random molecular clock based on nrITS phylogeny, which was the most complete data set regarding the representation of species and distribution areas. Ancestral distribution ranges were estimated for the nrITS data set as well as for a combined data set, revealing that Gagea most likely originated in southwestern Asia. This genus first diversified there starting in the Early Miocene. In the Middle Miocene, Gagea migrated to the Mediterranean and to East Asia, while migration into Euro‐Siberia took place in the Late Miocene. During the Pleistocene, the Arctic was colonized and Gagea serotina, the most widespread species, reached North America. The Mediterranean basin was colonized multiple times from southwestern Asia or Euro‐Siberia. Most of the currently existing species originated during the last 3 Ma.
