Figure 1From: Mining non-model genomic libraries for microsatellites: BAC versus EST libraries and the generation of allelic richnessNonrandom distribution of SSRs. Observed (black bars) and expected (white bars) counts of repeats of each sequence motif. Data are grouped by genomic library and by SSR motif size: (A) BAC library dinucleotide repeats and trinucleotide repeats, top and bottom, respectively; (B) EST library dinucleotide repeats and trinucleotide repeats, top and bottom, respectively. Observed values are based on posterior probability distribution of SSR motifs. BAC library SSRs show an excess of AT-rich repeat motifs, while EST library SSRs show a deficit of AT and CG motifs.Back to article page
