The evolution of sex determination continues to pose major questions in biology. Sex-
determination mechanisms control reproductive cell differentiation and development of …

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

Despite the prevalence of sexual reproduction across eukaryotes, there is a remarkable
diversity of sex‐determination mechanisms. The underlying causes of this diversity remain …

In species with separate sexes, the genome must produce two distinct developmental
programs. Sexually dimorphic development may be controlled by either sex-limited loci or …

Angiosperm sexual systems are fundamental to the evolution and distribution of plant
diversity, yet spatiotemporal patterns in angiosperm sexual systems and their drivers remain …

Anthropogenic activities have increased exposure to heavy metal pollution in previously
uncontaminated ecosystems, threatening plant communities. Considering that phenotypic …

Sexual system is a key determinant of genetic variation and reproductive success, affecting
evolution within populations and within clades. Much research in plants has focused on …

Aim Why some species exhibit larger geographical ranges than others remains a
fundamental, but largely unanswered, question in ecology and biogeography. In plants, a …

Sexual dimorphisms have been described in several groups of organisms, but while an
important number of investigations have focused on animal and plant systems, much less is …

Background Whether male and female gametes are produced by single or separate
individuals shapes plant mating and hence patterns of genetic diversity among and within …
