Figure 1 Geographic and genetic diversity in the CITP strain panel:(A) The CITP diversity panel represents 22 total nematode strains from three species, C. elegans (black circles), C. briggsae (orange triangles), and C. tropicalis (teal squares). (B) Two-dimensional representation of diversity and relatedness of the strains, LD1 and LD2 represent two latent dimensions. Bright colors indicate the core CITP strains (C. elegans: N2-PD1073, JU775, MY16; C. briggsae: AF16, HK104, ED3092; and C. tropicalis: JU1373, JU1630, QG843), while all other strains in the CITP diversity panel are indicated by muted colors. (C) Nucleotide diversity (π) of the strains used in the CITP diversity panel estimated on non-overlapping 100 kb genomic windows, core strains demonstrated by bright colors, all other strains of the panel in muted colors. The grey boxes represent the mean and the standard deviations.
