Although sex is a fundamental component of eukaryotic reproduction, the genetic systems
that control sex determination are highly variable. In many organisms the presence of sex …

Although individuals in most flowering plant species, and in many haploid plants, have both
sex functions, dioecious species—in which individuals have either male or female functions …

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

Almost all plants in the genus Populus are dioecious (ie trees are either male or female), but
it is unknown whether dioecy evolved in a common ancestor or independently in different …

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

Abstract The Hengduan Mountains (HDM) biodiversity hotspot exhibits exceptional alpine
plant diversity. Here, we investigate factors driving intraspecific divergence within a HDM …

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 …

The presence of thousands of independent origins of dioecy in angiosperms provides a
unique opportunity to address the parallel evolution of the molecular pathways underlying …

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 …
