Karyotypic variation and pollen stainability in resynthesized allopolyploids Tragopogon miscellus and T. mirus.

Premise Of The Study: Polyploidy has extensively shaped the evolution of plants, but the early stages of polyploidy are still poorly understood. The neoallopolyploid species Tragopogon mirus and T. miscellus are both characterized by widespread karyotypic variation, including frequent aneuploidy and intergenomic translocations.
