Hundreds of land plant lineages have independently evolved separate sexes in either
gametophytes (dioicy) or sporophytes (dioecy), but 43% of all dioecious angiosperms are …

The diversity of inflorescences among flowering plants is captivating. Such charm is not only
due to the variety of sizes, shapes, colors, and flowers displayed, but also to the range of …

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

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 …

Populus species have long been used as model organisms to study the adaptability of trees
and the evolution of sex chromosomes. As a species belonging to the section Populus and …

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) …

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 …

Summary The Salicaceae, including Populus and Salix, are dioecious perennials that utilize
different sex determination systems. This family provides a useful system to better …

Dioecious Salix evolved more than 45 million years ago, but have homomorphic sex
chromosomes, suggesting that turnover event (s) prevented major differentiation. Sex …
