 *A minimum of 6 repeat units (r.u.) for dinucleotides were used as parameters for searching microsatellites in genomic and EST sequence of carrot. Chisquared 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. χ^{2} = chisquare statistic; df = degrees of freedom. SSRs were nonrandomly distributed across motif types.
