Summary of chromosome changes observed in natural and synthetic A. suecica. Depicted are diagrams of 1x chromosome complements of A. thaliana, A. arenosa, or A. suecica, highlighting NORs, centromeres (CEN), and 5S loci. Arrows point out chromosomal changes detected in natural A. suecica strain LC1 or synthetic A. suecica-like allotetraploid F3 individual 1459a. For simplicity, the A. thaliana progenitor of natural A. suecica is depicted with only two 5S loci, as in ecotype No-0 (and many other ecotypes), but may have had three, as in Ler. Note that the precise chromosomes involved in the various gains, losses, or rearrangements of NORs and 5S loci are not known; thus, the arrows reflect only one of several possible explanations for the changes observed.
