Table 2 Departure of dinucleotide and trinucleotide genomic (BAC end, BSSR) and EST (ESSR) motifs from expected distributions*

From: Microsatellite isolation and marker development in carrot - genomic distribution, linkage mapping, genetic diversity analysis and marker transferability across Apiaceae

SSR type χ2 df p
BSSR dinucleotide 68 5 < 0.0001
BSSR trinucleotide 38 19 0.006
ESSR dinucleotide 6986 5 < 0.0001
ESSR trinucleotide 82 19 < 0.0001
  1. *A minimum of 6 repeat units (r.u.) for dinucleotides were used as parameters for searching microsatellites in genomic and EST sequence of carrot. Chi-squared distributions indicate comparison of observed SSR distribution of SSR motif types ((AT)n, (AC)n, (CG)n, etc.; (AAC)n, (ACC)n, (ACG)n, etc.) to posterior probabilities. Tests are partitioned by library and sequence motif. χ2 = chi-square statistic; df = degrees of freedom. SSRs were non-randomly distributed across motif types.
