Sex chromosome turnover has occurred in many groups, and is mediated by the
translocation or duplication of apical sex-determining genes, or the replacement of original …

Background Salicaceae species have diverse sex determination systems and frequent sex
chromosome turnovers. However, compared with poplars, the diversity of sex determination …

In the Vetrix clade of Salix, a genus of woody flowering plants, sex determination involves
chromosome 15, but an XY system has changed to a ZW system. We used genome …

The evolution of sex chromosomes can involve recombination suppression sometimes
involving structural changes, such as inversions, allowing subsequent rearrangements …

Transitions in the heterogamety of sex chromosomes (eg, XY to ZW or vice versa)
fundamentally alter the genetic basis of sex determination, however the details of these …

Background Sex chromosomes have evolved independently multiple times in eukaryotes
and are therefore considered a prime example of convergent genome evolution. Sex …

Dioecy, the presence of separate sexes on distinct individuals, has evolved repeatedly in
multiple plant lineages. However, the specific mechanisms by which sex systems evolve and …

Sex chromosomes have evolved independently multiple times in eukaryotes and are
therefore considered a prime example of convergent genome evolution. Sex chromosomes …

Most eukaryotes reproduce sexually and a wealth of different sex determination
mechanisms have evolved in this lineage. Dioecy or separate sexes are rare among …

Background Sex chromosomes have arisen independently in a wide variety of species, yet
they share common characteristics, including the presence of suppressed recombination …
