Study on Genetic Diversity of Phellodendron amurense based on cpDNA
Jiamusi University, Jiamusi City, Heilongjiang Province, 154007, China
In this study, 3 haplotypes were found in populations of Phellodendron amurense based on two combined cpDNA regions (psbA-trnH and trnT-trnL). Nucleotide diversity and haplotype diversity were 0.43×10-3 and 0.41, respectively at the level of species. The AMOVA revealed that only 8.53% of the variation was explained by differences among geographical groups, whereas inter-population and intrapopulation differences explained 18.32% and 71.35% of the variation, respectively. Phylogeographical relationships showed that all haplotypes were clustered into two lineages. Haplotype H1 and H2 cluster together, and Haplotype H3 composed a group. TCS network of haplotypes showed that haplotype H1 located in the center of the lineage, and it appears to be an ancestral haplotype. So we hypothesized that Northeast China populations and North China populations had a common origin. The mismatch distribution of this species suggested that all populations and populations in North China had not undergone recent expansion, but populations in Northeast China had undergone recent expansion. The results were consistent with the results of Tajima’s D and Fu’s and Li’s D test.
