Genetic diversity of Picea likiangensis natural population at different altitudes revealed by EST-SSR markers

Abstract: Altitude is thought to have greatly influenced current species distribution and their genetic diversity. However, it is unclear how different altitudes have affected the distribution and genetic diversity of Picea likiangensis, a dominant forestry species in the Qinghai-Tibetan Plateau region (QTP). In this study, we investigated the genetic diversity of Picea likiangensis populations which distributed in different altitudes of QTP using EST-SSR markers. The results suggested that this species has high genetic… Show more

“…In comparison with other coniferous species (Table ), its average expected heterozygosity is lower than Torreya grandis ( He = 0.432) (Zeng et al., 2018), Pinus massoniana ( He = 0.5717) (Zhang et al., 2014), Picea abies ( He = 0.616) (Stojnić et al., 2019), and P . likiangensis ( He = 0.7186) (Cheng et al., 2014); close to P . dabeshanensis ( He = 0.36) (Zhang et al., 2016) and Amentotaxus argotaenia ( He = 0.39) (Ruan et al, 2019); and higher than A .…”

“…This finding is likely to be associated with the unique biological characteristics and living habitats in the Reserve. Firstly, the widespread occurrence of wind pollination promotes outcrossing, which would favor increased genetic diversity of wild ancient tea tree populations [ 22 ]. Secondly, many tea trees in this area are more than 1000 years old as the largest and best-preserved wild ancient tea tree community found in the world, so the genes of wild ancient tea tree have been accumulated and preserved in the long-term natural selection, proving that Yunnan province is one of the places of origin of tea tree in the world [ 15 ].…”

“…Wild ancient tea trees (C. taliensis) are mostly about 1,000 years old and distributed mainly at the altitude of 2,000 to 2,500 m. And the rising altitudes can be a contributing factor to climate and habitat changes in this region [20]. Especially at the altitudes with vertical distances above 100 m, the environmental heterogeneity has an important impact on the growth, morphology, physiological metabolism of trees [21,22]. In this study, the leaf samples of wild ancient tea trees grown at different altitudes (Pop1: 2,050 m, Pop2: 2,200 m, Pop3: 2,350 m, and Pop4: 2,500 m) were collected and stored in silica gel.…”
