Map of Sample Collection Sites (a) and overview of the sample sources (b). (a) This map shows the geographic distribution of sample collection sites in southern China (including Guangxi, Guangdong, and Hainan) and Vietnam. The size of the red dots is proportional to the number of samples collected at each site (small dot: 10 samples; medium dot: 20 samples; large dot: 30 samples). A legend is provided in the upper right corner to explain the relationship between dot size and sample quantity. Provincial and national names are labeled in blue text, and a compass rose and scale bar (1000 km) are included for geographic reference. (b) The distribution of sample sources. The x-axis denotes the sources from which samples were isolated, while the y-axis indicates the total number of samples collected.
