Each chromosome of Chimonanthus campanulatus isolated from Figure 1, Figure 2, Figure 3 and Figure 4. For example, the chromosomes in Figure 5a were isolated from Figure 1a and Figure 1c, as indicated in the middle of each chromosome line. Because the (AG3T3)3 end signals likely affect the measurement of chromosome length, only the first and last chromosomes in Figure 1a,d,g, Figure 2a,d, Figure 3a,d, Figure 4a,d,g were measured for total length. The chromosomes were aligned based on length. The bottom numbers indicate chromosome counts. The four split chromosomes in Figure 4g,i (yellow arrows) were assembled into two chromosomes (17 and 22) based on their signal patterns.
