Two Alleles of NF-κB in the Sea Anemone Nematostella vectensis Are Widely Dispersed in Nature and Encode Proteins with Distinct Activities
Figure 5
Geographical distribution of Cys (C1-C4) and Ser NF-κB genotypes.
Pie graphs display the frequency of each genotype within the indicated populations (see Table 1 for details). The area of each graph reflects the relative sample size from that locale; for the large samples obtained at Chezzetcook (population 1), Kingsport (6), Sippewisset (13), and Rhode River (15), and the samples pooled from northern New England (7–12), the pie graphs are depicted at 50% or 25% of their relative size (as indicated on each graph). Populations 7–12 were grouped and populations 21–23 were grouped because the individual sites within each group are in close geographical proximity, and the groups exhibit no genotypic variability. The most abundant genotype, Cys/Cys, was found in every estuary sampled. With the exception of a few Ser/Ser individuals found in the lab population derived from Rhode River, Maryland, Ser/Ser homozygotes are restricted to Nova Scotia.
