Old-Growth Platycladus orientalis as a Resource for Reproductive Capacity and Genetic Diversity
Examining the genetic diversity and reproductive traits of old-growth and young populations of P. orientalis aims to ascertain whether the older populations contain a higher genetic diversity, more private alleles and a higher reproductive output compared with younger populations.

The distinctiveness between some introduced populations indicates multiple introductions of S. rostratum into China, and population structure analyses indicate that Chinese and U.S.A. populations are more closely related to each other than to sampled Mexican populations.
Mating system and pollination biology of a high-mountain perennial plant, Rhodiola dumulosa (Crassulaceae).
This research investigated the mating system characteristics and pollination biology of R. dumulosa, a perennial herb growing in a naturally fragmented habitat of high-mountain rocks, and assessed the relationship between its pollination and mating system.
Phylogeography and paleodistribution models of a widespread birch (Betula platyphylla Suk.) across East Asia: Multiple refugia, multidirectional expansion, and heterogeneous genetic pattern
The results reflect the relatively stable distribution through the last glacial–interglacial cycles and recent multidirectional expansion of B. platyphylla, providing new hypotheses for the response pattern of widespread tree species to climate change.
Population Genetic Diversity and Structure of a Naturally Isolated Plant Species, Rhodiola dumulosa (Crassulaceae)
The populations were significantly isolated, and gene flow was restricted throughout the entire distribution, however, gene flow among populations on the same mountain appears to be unrestricted, as indicated by the weak genetic isolation among these populations.
Phylogeographical patterns of an alpine plant, Rhodiola dumulosa (Crassulaceae), inferred from chloroplast DNA sequences.
The phylogeographical patterns of Rhodiola dumulosa, an alpine plant species restrictedly growing in the crevices of rock piles, were investigated based on 4 fragments of the chloroplast genome and it is proposed that this species migrated from refugia in the Qinghai-Tibetan Plateau to northern areas via the intervening highlands when temperatures increased.
Pollen limitation in invasive populations of Solanum rostratum and its relationship to population size
Aims small plant populations may be more likely to suffer more severe pollen limitation due to the lower number of potential mates or suitable pollinators. For invasive species, this phenomenon may…
Genetic diversity and population structure of the invasive plant Solanum rostratum in China
The level of genetic diversity of 13 Chinese populations of S. rostratum was investigated using nine microsatellite loci and the Weisanlu population in Hebei province was the highest and the Hohhot population was the lowest.
Patterns of Pollen Dispersal in an Invasive Population of Solanum rostratum (Solanaceae) in China
Paternity analysis, carried out on 13 microsatellite loci, was used to investigate pollen dispersal and mating patterns in an invasive population of Solanum rostratum in China, and results imply that successful invasion of S. rostrum is facilitated by a high level of pollen flow within the population.
Impacts of the removal of shrubs on the physiological and biochemical characteristics of Syntrichia caninervis Mitt: in a temperate desert
The results showed that the removal of shrubs significantly decreased chlorophyll fluorescence activity and soluble protein content in S. caninervis, especially under the total shrub removal treatment.
