Description
  • V této publikaci popisujeme vývoj genů pro ribosomální RNA v allotetraploidních druzích rostlin rodu Tragopogon. T. mirus a T. miscellus vznikly v době relativně nedávné přibližně před 80 lety. Pomocí molekulárních metod jsme zjistili, že rodičovské alely rDNA jsou v genomech dosud detekovatelné, avšak jejich vzájemný poměr kolísá a u většiny populací je rodičovská alela původem z T. dubius na ústupu. Výsledek je významný z hlediska současných hypotéz o evoluci genomu biologických druhů, které vznikly mezidruhovým křížením. (cs)
  • In this paper we have studied evolution of ribosomal RNA genes in Tragopogon allopolyploids. T. mirus and T. miscellus formed relatively recently some 80 years ago. Using molecular methods we detected both parental rDNA alleles in these allotetraploids. However their ratio varies between the populations and the alelle of T. dubius origin is often depleted. The result is significant for the current hypothesis on the evolution of biological species that arose by interspecfic hybridization.
