A map showing the sampled populations of <i>O</i>.

<p><b><i>rufipogon</i></b><b> and the distribution of haplotypes.</b> Detailed information of the samples is provided in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049546#pone.0049546.s005" target="_blank">Table S1</a>. Phylogenetic relationship of the haplotype based on the NJ analysis is indicated below the map. Pie charts show the proportions of the haplotypes within each population. Haplotypes are indicated by different colors. The Tropical of Cancer is indicated by the green dotted line. Codes: CL, Chaling; DX, Dongxiang; JH, Jinghong; JY, Jiangyong; YJ, Yuanjiang; ZP, Zhangpu;
