Figures & data
Figure 1. Photo taken at the Forest Genetics and Breeding Base of Northeast Forestry University on July 30, 2022. Eight-year-old B. pendula purple rain.
Figure 2. The map contains four rings. From the center going outward, the first circle shows the forward and reverse repeats connected with red and green arcs respectively. The next circle shows the tandem repeats marked with short bars. The third circle shows the microsatellite sequences identified using MISA. The fourth circle is drawn using drawgenemap and shows the gene structure on the plastome. The genes were colored based on their functional categories.
Figure 3. Phylogenetic tree reconstruction of 11 samples using maximum likelihood based on complete chloroplast genome. Note: The sequences of Betula pendula Purple Rain was from NGDC.;The remaining sequence data were from NCBI; represents the species in this study.
