Although species are central units for biological research, recent findings in genomics are
raising awareness that what we call species can be ill-founded entities due to solely …

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

Despite evidence of pollinator declines from many regions across the globe, the threat this
poses to plant populations is not clear because plants can often produce seeds without …

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 …

Sex chromosomes evolved from autosomes many times across the eukaryote phylogeny.
Several models have been proposed to explain this transition, some involving male and …

Sex determination evolved to control the development of unisexual flowers. In agriculture, it
conditions how plants are cultivated and bred. We investigated how female flowers develop …

Dioecy, the presence of male and female individuals, has evolved independently in multiple
flowering plant lineages,–. Although theoretical models for the evolution of dioecy, such as …

Asterids are one of the most successful angiosperm lineages, exhibiting extensive
morphological diversity and including a number of important crops. Despite their biological …

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 …

Nonrecombining sex chromosomes, like the mammalian Y, often lose genes and
accumulate transposable elements, a process termed degeneration. The correlation …
