“…For this species, the total genetic diversity (Ht) and intraspecies genetic diversity (Hs) were 0.1706 and 0.1149 respectively. Compared to the endangered plant E. mollis in previous RAPD-(Ht=0.359, Hs=0.302) and SSR-based (Ht=0.3173, Hs=0.2575) studies (Qin et al, 2006;Qin et al, 2010), E. macrophylla in the present study showed lower diversity. Similarly, the diversity values in the present study are lower than those estimated using ISSR markers for the coastal and island plants Ilex integra (Ht=0.223, Hs=0.153;Leng et al, 2005), Machilus thunbergii (Ht=0.269, Hs=0.186;Leng et al (2006), and Sonneratia caseolari (Ht=0.2103, Hs=0.1468Li et al (2004)) but higher than those reported for Neolitsea sericea (Ht=0.1248, Hs=0.0793; (Wang et al, 2004).…”

The genetic diversity and genetic structure of five natural populations of the island and coastal endangered plant Elaeagnus macrophylla were analyzed by conserved DNAderived polymorphism (CDDP) molecular markers. A total of 289 discernible loci were obtained from 102 individuals using fifteen primers, and 100% of the loci were polymorphic. The observed number of alleles (Na) was 1.9654, the effective number of alleles (Ne) was 1.2604, the average of Nei's genetic diversity index (H) was 0.1724, and Shannon's information index was 0.2869, indicating that E. macrophylla had levels of genetic diversity lower than those reported for continental relatives and other coastal species. The average percentage of polymorphic loci (PPL) was 42.1%, and the maximum and minimum PPL values were 80.97% and 14.88%, belonging to the Nanji Island (NJD) and Liugong Island (LGD) populations, respectively. Populations of E. macrophylla were highly differentiated (Gst=0.3263). The unweighted pair group method with arithmetic mean (UPGMA) clustering results revealed 5 groups: one group comprising the Liugong Island (LGD) and Da Rushan (DRS) populations, one comprising the Lingshan Island (LSD), Laoshan (LS) and Daguan Island (DGD) populations, one comprising the Putuo Island (PTD), and two groups representing the Nanji Island (NJD) samples, which were differentiated into a northwestern group and a southeastern group. There was no cross-clustering among the samples, and the similarity of the relatives was strictly related to geographical location. R software analysis showed no correlation between genetic distance and geographic distance between populations (r = 0.256579, p = 0.8309).

“…The eco-environmental characteristics of E. mollis are typically efficient heat energy, little annual rainfall, and poor stands Zhang et al, 2001). Recent habitat fragmentation has affected all E. mollis populations by reducing their size and increasing their isolation (Qin et al, 2006(Qin et al, , 2010.…”

“…The endangered status of E. mollis may not be related to low genetic diversity but instead to the specific breeding system of the species, as well as ecological factors (Qin et al, 2006(Qin et al, , 2010Xu et al, 2011). The endangered status of E. mollis may also be caused by strong artificial interference.…”

ABSTRACT.Elaeagnus mollis Diels is a group of shrubs and dwarf trees endemic to China and are endangered plants. However, the reason why these plants are endangered remains controversial. The current study aimed to explore the endangered status of E. mollis from a genetic perspective and to propose conservation strategies for this species. Using 16 polymorphic allozyme loci, the population genetic structure was investigated for three populations representing the taxa and variants. The variants exhibited relatively high levels of genetic variation compared to other woody shrubs with similar geographic distributions. The overall genetic diversity (H E = 0.352) was elevated compared to long-lived woody angiosperms. The average number of alleles per locus (A), percentage polymorphic loci (P), and observed heterozygosity (H O ) were 2.0, 85.2, and 0.371, respectively. Furthermore, gene flow estimates within the population groups were also elevated. The life history and habitats of E. mollis play major roles in the levels of genetic diversity. The results of this study may help to device strategies for preserving the genetic diversity of E. mollis and 5951 Population genetic structure of Elaeagnus mollis ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (2): 5950-5957 (2015) for promoting planting.
