Population structure of 24 B. cartharticus accessions based on UPGMA and Bayesian clustering (STRUCTURE, K = 6). All accessions were grouped into four clusters. The accession codes with red, blue, yellow, and black indicated that these accessions were collected from South America, North America, Asia, and Europe, respectively. All accessions colored based on the sample origins were divided into four UPGMA clusters and five STRUCTURE subgroups (represented by five colors: blue-green, purple, orange, green, and light yellow). The numbers beside each branch represent bootstrap values, and only the numbers higher than 40% are presented
