Figure 1.

Nucleotide variation across the O. sativa Wx genomic region on chromosome 6. Approximately 500-bp portions of 12 flanking genes were sequenced, along with the entire Wx gene. The approximate genomic locations of the genes are indicated by solid bars, with gene identities as follows: (1) hypothetical protein, (2) hypothetical protein, (3) receptor-like protein kinase, (4) expressed protein, (5) putative glycosyl hydrolase family 17, (6) hypothetical protein, (7) Waxy, (8) transketolase, (9) hypothetical protein, (10) expressed protein, (11) enolase, (12) kinesin-like protein, and (13) putative ribosome-binding factor A. Shaded bars indicate the ratios of silent-site nucleotide diversities for those individuals with and without the Wx splice donor mutation. The smallest bars are equivalent to a ratio of 0.
