Molecular phylogeny and biogeography of the arctic‐alpine genus Lagotis (Plantaginaceae)

Abstract: It has been suggested that many plants now found in the arctic originated from ancestors that occurred at high altitudes in the southern mountains of the Northern Hemisphere during the Tertiary. However, this hypothesis has rarely been tested using a molecular phylogenetic approach. Here, we present a fossil‐calibrated molecular phylogeny of Lagotis, an arctic‐alpine genus with the greatest diversity in the Qinghai‐Tibetan Plateau (QTP) and Central Asian mountains, based on five chloroplast (matK, psbA‐trnH, r… Show more

“…Most QTP endemic genera originated in situ or in adjacent regions (e.g., Liu et al, ; Wang et al, ; Zhang et al, ; Zhou et al, ), although a few diverged from their sister genera or clades in other regions, far away from the QTP (e.g., Liu et al, ; Tu et al, ). Similarly, widespread genera occurring in both the QTP and other regions may have diverged from their sister clades in the QTP (e.g., Wang et al, ; Zhang et al, ; Jia et al, ; Li et al, ), adjacent regions (Wang et al, ; Zhang et al, ), or far away from the QTP (Milne et al, ). In most cases, it is difficult to determine the accurate origin location of some species‐rich genera due to frequent long‐distance dispersals, although they undoubtedly originated in Eurasia (Mao et al, ).…”

“…The relatively common occurrence of homoploid hybrid speciation in the QTP was ascribed to a special combination of frequent interspecific hybridization and newly created habitats by both geological and climatic changes (Sun et al, ). It should be noted that some genera or lineages diversified initially in the QTP and then migrated out of the QTP (Zhang et al, ; Jia et al, ; Sun et al, ; Nie et al, ; Li et al, ).…”
