Extended Data Fig. 9: Aneuploidy is frequently observed in synthetic A. suecica.
From: Gradual evolution of allopolyploidy in Arabidopsis suecica
a, Comparison of FISH analyses of the reference natural A. suecica ‘ASS3’ and synthetic A. suecica. Synthetic A. suecica shows aneuploidy in both subgenomes in the F2 generation (gain of one chromosome on the A. thaliana subgenome (N=11) and loss of one chromosome on the A. arenosa subgenome (N=15)). Natural A. suecica shows a stable karyotype b, DNA-sequencing coverage in the reference natural A. suecica accession ‘ASS3’ c and d, DNA-sequencing coverage in siblings of F1 synthetic A. suecica show different cases of aneuploidy (indicated with arrow) in synthetic A. suecica, chromosome 4 in c and chromosome 11 in d e overlap of genes involved in cell division from Fig. 5e and genes previously shown to play a role in the adaptation to autopolyploidy in A. arenosa121. The little overlap in genes between A. suecica and A. arenosa highlights that successful meiosis in polyploids is likely a complex trait.
