UPGMA dendrogram constructed based on the genetic similarity of 21 weedy rice populations.
<p>Similarity was estimated by 23 SSR loci, using cultivated (CV) and wild rice (Wild) as two reference groups.</p
The 23 SSR primer pairs used in this study with detail information on their DNA sequences, motifs, molecular weight, and expected heterozygosity in the examined weedy rice materials.

Number of pair-wise migrants per generation (<i>Nm</i>) between 21 weedy rice populations and cultivated rice group (CV) calculated based on the formula proposed by Slatkin and Barton [28].

Correlation between genetic diversity and the average number of immigrants of a particular weedy rice population.

Geographical locations of the 21 weedy rice populations collected from Sri Lanka.
<p>The population codes at each collection site are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0112778#pone-0112778-t001" target="_blank">Table 1</a>.

The colors in pies are corresponded to those in the STRUCTURE analysis for weedy rice populations.</p

Genetic relationships of 21 weedy rice populations (Am-1 to Pu-2) and rice varieties (CV) from STRUCTURE analysis.
<p>Each individual is represented by a vertical bar assigned into three colors, with height proportional to each of the three inferred genetic components. The numbers beside vertical axis represent probability of assignment.</p
