Figure 2

Included parts of XY1. Thick grey lines indicate parts of the XY1 region included in the long (upper line) and reduced (lower line) alignments. Dotted lines indicate parts that were excluded. Recombination breakpoints suggested from the GARD analysis are indicated with arrows. The black boxes indicate exons, thin lines introns. The PCR primer positions are indicated below by arrows (sequence-specific primers not included). The intron/exon figure is redrawn from Atanassov & al. [29], and the lengths are based on S. latifolia Y1 sequences.
