Frequency distributions of SSR alleles for two additional loci. Unlike the Hawaiian mints' FCA-like locus, frequency distributions of SSR alleles for two additional loci do not show archipelago-wide geographic progression. A, unigene 260708 (no annotation); B, unigene 261064 (annotated as At4g23400.1-major intrinsic family protein/MIP family protein [16]). Insets, average allele lengths for each island with ± 0.5 standard deviations. As described previously [16], the frequency distribution for A shows both left and right tails, representing samples principally from the island of Hawai'i. In B, the allele frequency distribution is substantially right-shifted, the four longest alleles representing a single taxon from Maui Nui (Stenogyne bifida). Numbers of individuals genotyped for A and B, respectively, were 93 and 91. A, Kruskal-Wallis and ANOVA n.s.; B, Kruskal-Wallis P < 0.05, ANOVA P < 0.001. B, Tamhane's T2 is significant only for the Maui Nui/Hawai'i post hoc comparison, P < 0.05.
