图1 基于SNP的荷叶铁线蕨遗传结构分析。A: 当K = 2时每个个体的遗传成分分析结果和基于9,423个SNP的最大似然法建树结果示。每一个柱形代表1个样本, 每种颜色代表1个遗传簇; B: 最佳聚类结果的地理分布, 其中的饼状图代表每个居群的遗传簇; C: 主成分分析结果, 图中每个点代表1个样品。样品信息同表1。

Fig. 1 Analysis of population structure based on identified SNP. A, Results of the admixture proportions for each individual with K = 2 and maximum likelihood tree based on 9,423 SNPs. Each sample is represented by a histogram, which is partitioned into different colors. Each color represents a genetic cluster. Numbers in the nodes are the bootstrap values from 100 replicates; B, The distribution of best results in clusters by Structure. The pie chart represents the genetic cluster of each population; C, Results of the principal component analysis. Each sample is represented by a point. The sample information is shown in Table 1.
