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 …

Although hundreds of plant lineages have independently evolved dioecy (that is, separation
of the sexes), the underlying genetic basis remains largely elusive. Here we show that …

Genetic determination of gender is a fundamental developmental and evolutionary process
in plants. Although it appears that dioecy in Populus is genetically controlled, the precise …

A well-established hypothesis for the evolution of dioecy involves two genes linked at a sex-
determining region (SDR). Recently there has been increased interest in possible single …

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 …

The genus Populus features a genetically controlled sex determination system, located on
chromosome 19. However, different Populus species vary in the position of the sex‐linked …

Separate sexes and sex-biased gene expression have repeatedly evolved in animals and
plants, but the underlying changes in gene expression remain unknown. Here, we studied a …

Epigenetic regulation can add a flexible layer to genetic variation, potentially enabling long-
term but reversible cis-regulatory changes to an allele while maintaining its DNA sequence …

We have embarked on a molecular cloning approach to the investigation of sex
determination in Silene Iatifolia Poiret, a dioecious plant species with morphologically …

Sex determination is a process that leads to the physical separation of male and female
gamete-producing structures to different individuals of a species. Even though sexually …
