Nucleotide diversity of flanking region (2 Mb) of the Pi-ta gene in US weedy rice and cultivated rice groups of O. sativa, and O. rufipogon.

1BR and MIX of weedy rice and US cultivars were excluded from tropical japonica samples in this analysis.2Indicates sample size.3Indicates number of sites, sequence align gaps were not included for analyzing polymorphisms of all sequences.4Indicates number of polymorphic (segregating) site.5Indicates silent nucleotide polymorphism6Indicates nucleotide diversity based on silent site.
