Plant sex chromosomes defy evolutionary models of expanding recombination suppression and genetic degeneration
Hundreds of land plant lineages have independently evolved separate sexes in either
gametophytes (dioicy) or sporophytes (dioecy), but 43% of all dioecious angiosperms are …

Pathways to sex determination in plants: how many roads lead to Rome?
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 …

A single gene underlies the dynamic evolution of poplar sex determination
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 …

The persimmon genome reveals clues to the evolution of a lineage-specific sex determination system in plants
Most angiosperms bear hermaphroditic flowers, but a few species have evolved outcrossing
strategies, such as dioecy, the presence of separate male and female individuals. We …

Reinvention of hermaphroditism via activation of a RADIALIS-like gene in hexaploid persimmon
In flowering plants, different lineages have independently transitioned from the ancestral
hermaphroditic state into and out of various sexual systems. Polyploidizations are often …
