Repetitive DNA sequences playing critical roles in driving evolution, inducing variation, and
regulating gene expression. In this review, we summarized the definition, arrangement, and …

Over the past 20 years, tremendous advances in sequencing technologies and
computational algorithms have spurred plant genomic research into a thriving era with …

Bryophytes occupy a basal position in the monophyletic evolution of land plants and have a
life cycle in which the gametophyte generation dominates over the sporophyte generation …

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

In many eukaryotes, genetic sex determination is not governed by XX/XY or ZW/ZZ systems
but by a specialized region on the poorly studied U (female) or V (male) sex chromosomes …

Sex chromosome evolution is thought to be tightly associated with the acquisition and
maintenance of sexual dimorphisms. Plant sex chromosomes have evolved independently …

Poplar (Populus) is a well-established model system for tree genomics and molecular
breeding, and hybrid poplar is widely used in forest plantations. However, distinguishing its …

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 …

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 determination is a central process for sexual reproduction and is often regulated by a
sex determinant encoded on a sex chromosome. Rules that govern the evolution of sex …
