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 …

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 …

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 …

The plant genome is organized into chromosomes that provide the structure for the genetic
linkage groups and allow faithful replication, transcription and transmission of the hereditary …

Almost all plants in the genus Populus are dioecious (ie trees are either male or female), but
it is unknown whether dioecy evolved in a common ancestor or independently in different …

Sex chromosomes differ from other chromosomes in the striking divergence they often show
in size, structure, and gene content. Not only do they possess genes controlling sex …

All species of the genus Populus (poplar, aspen) are dioecious, suggesting an ancient origin
of this trait. Despite some empirical counter examples, theory suggests that nonrecombining …

Dioecy, the presence of separate sexes on distinct individuals, has evolved repeatedly in
multiple plant lineages. However, the specific mechanisms by which sex systems evolve and …

It is now well established that plants have an important place in studies of sex chromosome
evolution because of the repeated independent evolution of separate sexes and sex …
