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 …

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 …

A Y-encoded suppressor of feminization arose via lineage-specific duplication of a cytokinin response regulator in kiwifruit
Dioecy, the presence of male and female flowers on distinct individuals, has evolved
independently in multiple plant lineages, and the genes involved in this differential …

Sex determination by two Y-linked genes in garden asparagus
The origin and early evolution of sex chromosomes have been hypothesized to involve the
linkage of factors with antagonistic effects on male and female function. Garden asparagus …
