Abstrakt:
The plant mt genomes are highly dynamic. Their evolution is driven by
frequent rearrangements and gene transfers, whereas substitution rate is generally
slow with several exceptions. The genus Silene (Caryophyllales) represents one of
them and exhibits high mutation rate in mt DNA. The gynodioecious species
(producing female and hermaphroditic individuals) of this genus show also a high
polymorphism in mt DNA due to the balancing selection in favor of various mt
genomes in the same population. Thus, Silene species possess plenty of mt markers,
which facilitate the study of the impact of mt genome rearrangements on mt gene
expression and function. They are also good models for the investigation of
functional and evolutionary aspects of heteroplasmy, the situation when two or
more organelles with distinct genomes co-occur in the same individual.
