• Premise of the study: Separating sexual function between different individuals carries risks,
especially for sedentary organisms. Nevertheless, many land plants have unisexual …

Genomic analysis of many nonmodel species has uncovered an incredible diversity of sex
chromosome systems, making it possible to empirically test the rich body of evolutionary …

Sex chromosomes in land plants can evolve as a consequence of close linkage between the
two sex determination genes with complementary dominance required to establish stable …

Chromosomal inversions have the potential to play an important role in evolution by
reducing recombination between favorable combinations of alleles. Until recently, however …

In species with separate sexes, sex determination often has a genetic basis, and in a wide
diversity of taxa a pair of cytologically distinguishable 'sex chromosomes' are found such that …

Sex determination in papaya is controlled by a recently evolved XY chromosome pair, with
two slightly different Y chromosomes controlling the development of males (Y) and …

Animal sex chromosomes typically carry the upstream sex-determining gene that triggers
testis or ovary development and, in some species, are regulated by global dosage …

Teleost fishes, thanks to their rapid evolution of sex determination mechanisms, provide
remarkable opportunities to study the formation of sex chromosomes and the mechanisms …

Sex chromosomes can evolve once recombination is halted between a homologous pair of
chromosomes. Owing to detailed studies using key model systems, we have a nuanced …

Summary White campion (Silene latifolia, Caryophyllaceae) was the first vascular plant
where sex chromosomes were discovered. This species is a classic model for studies on …
