  • a Variation in noncoding regions and at synonymous sites in coding regions. Sites included in complex codons are not considered in nucleotide diversity estimates.

  • b Total number of sequences.

  • c Number of locations sampled.

  • d Number of segregating sites.

  • e Average number of pairwise differences.

  • f Average number of pairwise differences within locations.

  • g Average number of pairwise differences between locations.

  • h Significance of the Snn statistic (Hudson 2000).

  • * P < 0.05

  • *** P < 0.001.

  • i Number of substitutions per total site [with the Jukes and Cantor (1969) correction] vs. A. thaliana.

  • j Number of substitutions per silent site [with the Jukes and Cantor (1969) correction] vs. A. thaliana.
