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

Sex chromosomes can evolve when recombination is halted between a pair of
chromosomes, and this can lead to degeneration of the sex-limited chromosome. In the early …

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 …

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

The heritability of gene expression is critical in understanding heterosis and is dependent on
allele-specific regulation by local and remote factors in the genome. We used RNA-Seq to …

Abstract Background and Aims The largest genus of Salicaceae sensu lato, Salix, has been
shown to consist of two main clades: clade Salix, in which species have XY sex …

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

Salix triandra belongs to section Amygdalinae in genus Salix, which is in a different section
from the willow species in which sex determination has been well studied. Studying sex …

Sex determination systems in plants can involve either female or male heterogamety (ZW or
XY, respectively). Here we used Illumina short reads, Oxford Nanopore Technologies (ONT) …

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 …
