Genome map of P. salicina ‘Sanhua plum’ plastome. The map has four rings, from the center outward, with red and green arcs on the first circle connecting forward and reverse repeats, respectively; the second ring shows tandem repeats marked with dashes; the third ring is a MISA-identified microsatellite sequence; and the fourth ring shows the gene structure on the plastome. The colors of these genes are classified according to their function, as shown in the lower left corner
