Comparative analysis of plastid genomes from allopolyploid Tragopogon miscellus and its diploid parents.

ABSTRACT: Tragopogon is a model system for the study of recent, recurrent, and reciprocal allopolyploid formation. Recent research has focused on the fates of nuclear genes duplicated in the allopolyploid T. miscellus relative to the parental diploids, T. dubius and T. pratensis. In contrast, little attention has been given to organellar genomes, which interact with the duplicated nuclear genomes via their gene products. Here we reconstructed plastid genomes (plastomes) for representatives of these three species to investigate their structure and variability among natural and synthetic allopolyploids. Genomic libraries were Illumina-sequenced for several individuals of the allopolyploid T. miscellus and its diploid parents. Whole plastomes were assembled from skimmed data with comparative analyses u
