Figures & data
Figure 1. Species image of Z. mairei. (A) Morphology of the whole plant. Z. mairei is a spinose tree of 15 m in height. (B) Morphological characteristics of leaves of Z. mairei. Leaves papery, ovate-lanceolate, and apically long acuminate. The photograph was taken by the corresponding author Yuan Huang at Kunming Botanic Garden, Yunnan Province of China (25°14'56"N, 102°74'07"E), on March 2023.
Figure 2. Genomic map of overall features of the chloroplast genome of Z. mairei by CPGview. The map contains six tracks from the center outward. The first track represents the dispersed repeats, the red arcs represent the direct repeats and the green arcs represent the palindromic repeats. The second track is a long tandem repeat marked by short blue bars. The third track shows the short tandem repeats or microsatellite sequences as short bars of different colors. The fourth track is the tetrameric structure of the chloroplast genome, containing LSC, IRa, SSC, and IRb. The fifth track is the GC content of the chloroplast genome. The last track is coding genes categorized according to function. The transcription directions for the inner and outer genes are clockwise and anti-clockwise, respectively.
Figure 3. A phylogenetic tree was constructed using the maximum-likelihood method based on complete chloroplast sequences from 23 Rhamnaceae species and 2 Vitaceae species as outgroups.
