Figure 4From: Genetic diversity, genetic structure and demographic history of Cycas simplicipinna(Cycadaceae) assessed by DNA sequences and SSR markersNeighbor-joining trees were built by using genetic distance based on eight cpDNA (a) and five nrDNA (b) haplotypes of C. simplicipinna . Bootstrap values were shown on branches and divergency times were shown on the nodes. MYA represent million years ago. The symbols BOL-NBH in the bracket represent population codes.Back to article page
