Although individuals in most flowering plant species, and in many haploid plants, have both
sex functions, dioecious species—in which individuals have either male or female functions …

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 …

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 …

Background Sex chromosomes have arisen independently in a wide variety of species, yet
they share common characteristics, including the presence of suppressed recombination …

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 …

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 …

Unisexuality in flowering plants evolved from a hermaphrodite ancestor. Transition from
hermaphrodite to unisexual flowers has occurred multiple times across the different lineages …

Plant sex chromosomes can be vastly different from those of the few historical animal model
organisms from which most of our understanding of sex chromosome evolution is derived …

Dioecy has evolved numerous times in plants, but heteromorphic sex chromosomes are
apparently rare. Sex determination has been studied in multiple Salix and Populus …

Abstract Willows (Salix) and poplars (Populus) are dioecious plants in Salicaceae family.
Sex chromosome in poplar genome was consistently reported to be associated with …
