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 …

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 …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Background Salicaceae species have diverse sex determination systems and frequent sex
chromosome turnovers. However, compared with poplars, the diversity of sex determination …

The genus Silene, studied by Darwin, Mendel and other early scientists, is re-emerging as a
system for studying interrelated questions in ecology, evolution and developmental biology …

Genomic regions determining sexual compatibility often display recombination suppression,
as occurs in sex chromosomes, plant self‐incompatibility loci and fungal mating‐type loci …

The dioecious plant Silene latifolia possesses evolutionarily young sex chromosomes, and
so serves as a model system to study the early stages of sex chromosome evolution. Sex …

The ability to identify genetic markers in nonmodel systems has allowed geneticists to
construct linkage maps for a diversity of species, and the sex-determining locus is often …

Silene latifolia is a dioecious plant with heteromorphic sex chromosomes that have
originated only∼ 10 million years ago and is a promising model organism to study sex …

Sex chromosomes evolved many times independently in many different organisms [1].
According to the currently accepted model, X and Y chromosomes evolve from a pair of …
