Microsatellite data in GenePop format for Lactuca serriola in Europ

Model-based populations in the cucumber mega-population.

<p>(A) Delta K values for different numbers of populations assumed (K) in the STRUCURE analysis. (B) Classification of 3,342 accessions into three populations using STRUCTURE 2.3.1. The distribution of the accessions to different populations is indicated by the color code (P1: red, P2: yellow, P3: blue). Numbers on the y-axis show the subgroup membership, and the x-axis shows the different accession. (C) Unrooted Neighbor-Joining (NJ) tree of the 3,342 accessions. Bootstrap values are indicated at the major branches. (D) Principal Component Analysis (PCA) of the 1,026 accessions without missing SSR fingerprinting data. Color codes for each population and admixture are consistent in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0046919#pone-0046919-g002" target="_blank">Figure 2C, 2D</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0046919#pone-0046919-g003" target="_blank">Figure 3</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0046919#pone-0046919-g004" target="_blank">Figure 4C</a>.</p

Characteristics of the 23 investigated SSR markers and the diversity detected in 3,342 cucumber accessions.

<p>Na: the observed number of alleles; Ne: the effective number of alleles; H_o: observed heterozygosity; H_e: expected heterozygosity; I: Shannon's information index; PIC: polymorphism information content.</p
