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

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

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 …

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

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 …

How do separate sexes originate and evolve? Plants provide many opportunities to address
this question as they have diverse mating systems and separate sexes (dioecy) that evolved …

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 …

The areca palm (Areca catechu) has a monoecious spadix, with male flowers on the apical
side and females on the basal side. Here, we applied multiomics analysis to investigate 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 …
