Fig. 1: Overview of bat sampling and bat coronaviruses identified in this study.

a Bat sampling in different provinces. The pie chart on the left side of the map illustrates the proportion of bat species sampled in 14 different provinces in China. The colors in the pie chart represent different species, consistent with the colors assigned to branches on the evolutionary tree based on cytb. The branches of the evolutionary tree are color-coded according to the bat’s family (Supplementary Data 2). Map data were retrieved from Tianditu (https://www.tianditu.gov.cn/) (b) Sampling locations and numbers in this study. The sampling points in this study are marked on the map as red dots, with the size of the dots proportional to the number of samples collected (Supplementary Data 2). Map data were retrieved from zenodo (DOI: 10.5281/zenodo.4167299) (c) Overview of identified Strains in this study. The stacked bar chart represents the number of strains identified in this study based on RDRP and complete genomes. It also compares the number of complete genomes identified in this study with those identified by others (Supplementary Data 2 and Data 6).
