Chromosomal localization of the <i>S-RNase</i>, <i>SFB</i>, <i>SFBB</i>, and <i>SLFL</i> lineage genes.

<p><i>P</i>. <i>persica</i> (A), <i>M</i>. <i>domestica</i> (B), and <i>F</i>. <i>vesca</i> (C) <i>S-RNase</i> lineage genes are marked in pink, <i>SFB</i>, <i>SFBB</i>, and <i>SLFL</i> lineage genes are marked in blue. Different shapes represent the different <i>S-RNase</i> and F-box <i>SFB-</i>, <i>SFBB-</i>, and <i>SLFL-</i> lineage genes. To represent two or more sequential genes, a bracket at the left of the chromosome is used. Each <i>Prunus</i> chromosome is marked in a different colour: PG1- pink, PG2 light green, PG3 light blue, PG4- purple, PG5- yellow, PG6-green, PG7- orange, and PG8-red. These colours are then used to assign the synteny regions for the <i>M</i>. <i>domestica</i> and <i>F</i>. <i>vesca</i> chromosomes, according to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126138#pone.0126138.g001" target="_blank">Fig 1</a>in Jung <i>et al</i>., [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126138#pone.0126138.ref065" target="_blank">65</a>]. Regions with unknown synteny but between regions that show synteny with the same chromosome are marked in stripes, and regions with unknown synteny between syntenic regions from different chromosomes are marked in grey. Brackets on the right of each chromosome represent the nine ancestral synteny regions (1 to 9) according to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126138#pone.0126138.g004" target="_blank">Fig 4</a> in Illa et al.
