Fig. 1: The landscape of sampling and variants in sequenced moso bamboo individuals.

a The sampling locations of 15 major moso bamboo geographic areas are indicated with red points, and five empirically assigned phylogenetic groups according to the genetic structure and large-scale geographic distribution are represented in light shades. The map was drawn based on ETOPO2v2c Global Gridded 2-min elevation and bathymetric data (doi: 10.7289/V5J1012Q). b Circos plot for the visualization of different types of detected variants in the moso bamboo population at the genome-wide level. The tracks from outside to the inside represent the density of SNPs (single-nucleotide polymorphisms), InDels (small insertions and deletions), large deletions (DELs), insertions (INSs), inversions (INVs), intrachromosomal translocations (ITX), gained copy number variations (CNVs), and lost CNVs. Variant density was calculated in non-overlapping 100-kb window intervals. c Heterozygous genotype frequency in non-overlapping 200-kb windows genome wide. The red and green dashed lines represent the thresholds of high and low heterozygous genotype frequencies, respectively. The long continuous heterozygous SNPs clustered regions of high frequency (high-LCHRs) and long continuous heterozygous SNPs clustered regions of low frequency (low-LCHRs) are shaded in red and green, respectively. d The dot plot shows the gene ontology (GO) enrichment of genes located in high-LCHRs. e The dot plot shows the GO enrichment of genes located in low-LCHRs. The color of the points represents the Benjamini–Hochberg corrected p-value, and the size of points represents the number of genes. Rich factor is the ratio of the number of interested genes annotated in this GO term to all genes in this GO term. Source data underlying b–e are provided as a Source Data file.
