[Abstract]:By analyzing and comparing the research results of population genetics and phylogenetic geography of Tertiary relict plants in East Asia in recent years, the patterns of their pedigree geographical pattern are summarized, and the common geological history or climatic causes of their formation are analyzed. The prospect of future research is put forward. The phylogenetic patterns of relict plants in East Asia are as follows: (1) the cold and dry climate from the middle to the late Miocene led to the recent species formation of the relict plants. However, the late Pliocene and Pleistocene climatic changes promoted their intraspecific lineage differentiation, genetic diversity formation, and population contraction and expansion. The contraction and expansion of the population resulted in the formation of "suture zones" in some groups. (2) because different plant groups have different niche needs and biological characteristics, The East China Sea continental bridge exposed during the Pleistocene glacial period has different "filtering" and "corridor" effects on the intermittent distribution of relict plants in China and Japan. This resulted in different genetic segregation patterns. (3) the rapid uplift of the Qinghai-Tibet Plateau at the end of the Pliocene and the enhancement of the East Asian monsoon climate at the end of the Pliocene / early Pleistocene may be the relict plants distributed along Sichuan in several subtropical regions. The root cause of east-west pedigree differentiation in the vicinity of the basin, It is also a driving factor for the east-west lineage differentiation of relict plants in the arid zone of the northwest. (4) the global climate has cooled and dried since the late Miocene, which has driven some Tertiary relict plants from the mainland of China before the Pleistocene. Japan moved to Taiwan, And isolated and differentiated, forming a new species or geographical pedigree. In short, history and contemporary geography and environment affect the geographical distribution, genetic diversity, pedigree differentiation and species formation of Tertiary relict plants in East Asia. Finally, we emphasize the lack of research caused by the use of simple molecular clock models of unit points, and present a prospect for future research. That is, the use of genomic data and biogeographic models as well as the integration of phylogenetic studies at community level are the future research directions.
