Fig. 6: Diversity and structural variations in A. digitata.
From: Chromosome-level baobab genome illuminates its evolutionary trajectory and environmental adaptation
a Principal Component Analysis (PCA) of 25 A. digitata accessions collected across Africa using 6490 SNPs. Three clusters are present: Cluster 1 (Pop1: n = 8), Cluster 2 (Pop2: n = 13), Cluster 3 (Pop3: n = 4). b Weighted Fst (fixation index) values between populations: Pop1 vs. Pop2 (Fst = 0.47), Pop1 vs. Pop3 (Fst = 0.13), and Pop2 vs. Pop3 (Fst = 0.41). The high Fst values support population differentiation due to genetic structure, primarily associated with longitudinal variation (east-west). c Lostruct partitions vary across chromosomes. The multidimensional scaling shows the coordinates of the 25 A. digitata populations on the x-axis (MDS 1) and the y-axis (MDS 2). Points that are not outliers are shown in black, while points that are outliers are shown in green (LS1), orange (LS2), and purple (LS3). Each point on the graph corresponds to a specific genomic window of 3 kb. MDS stands for multidimensional scaling.
