Transcriptome dynamics of the inflorescence in reciprocally formed allopolyploid Tragopogon miscellus (Asteraceae)

Multiple origins of polyploids are now considered the rule, not the exception. However, how recurrent polyploidization events contribute to the genetic diversity of polyploids remains largely unknown. As a special case of recurrent polyploidy, the recently formed allotetraploid T. miscellus has formed reciprocally in nature with divergent inflorescence morphologies, i.e. short- vs. long-liguled forms. We reports the transcriptome diversity of the inflorescence that has resulted from reciprocal polyploidizations in T. miscellus.
