Figure 3

The recombinant event of SH1211 was analyzed by the BootScan method in software RDP4. The 𝑥-axis shows the position in alignment, and the 𝑦-axis shows the bootstrap support (%). Major parent plot (blue line) and minor parent plot (purple line) cross two areas (pink regions), which represent the recombinant regions, and the numbers of approximate 𝑃 values locate at the top of pink regions, respectively. The bootstrap cut-off is 70%.
