DNA methylation and genetic degeneration of the Y chromosome in the dioecious plant Silene Iatifolia

Popis výsledku v původním jazyce

Background: S. Iatifolia is a model organism for the study of sex chromosome evolution in plants. Its sex chromosomes include large regions in which recombination became gradually suppressed. The regions tend to expand over time resulting in the formation of evolutionary strata. Non-recombination and later accumulation of repetitive sequences is a putative cause of the size increase in the Y chromosome. Gene decay and accumulation of repetitive DNA are identified as key evolutionary events. Transposons in the X and Y chromosomes are distributed differently and there is a regulation of transposon insertion by DNA methylation of the target sequences, this points to an important role of DNA methylation during sex chromosome evolution in Silene Iatifolia. The aim of this study was to elucidate whether the reduced expression of the Y allele in S. Iatifolia is caused by genetic degeneration or if the cause is methylation triggered by transposons and repetitive sequences.
