A major reason for studying plant sex chromosomes is that they may often be
'young'systems. There is considerable evidence for the independent evolution of separate …

We discuss the genetic, demographic, and selective forces that are likely to be at play in
restricting observed levels of DNA sequence variation in natural populations to a much …

How do separate sexes originate and evolve? Plants provide many opportunities to address
this question as they have diverse mating systems and separate sexes (dioecy) that evolved …

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 …

Cannabis sativa–derived tetrahydrocannabinol (THC) production is increasing very fast
worldwide. C. sativa is a dioecious plant with XY Chromosomes, and only females (XX) are …

Mutation is the source of all heritable diversity, the essential material of evolution and
breeding. While mutation rates are often regarded as constant, variability in mutation rates …

Genetic degeneration is an extraordinary feature of sex chromosomes, with the loss of
functions of Y-linked genes in species with XY systems, and W-linked genes in ZW systems …

Abstract About 15,000 angiosperm species (∼ 6%) have separate sexes, a phenomenon
known as dioecy. Why dioecious taxa are so rare is still an open question. Early work …

In flowering plants, different lineages have independently transitioned from the ancestral
hermaphroditic state into and out of various sexual systems. Polyploidizations are often …

Recombination suppression around sex-determining gene (s) is a key step in evolution of
sex chromosomes, but it is not well understood how it evolves. Recently evolved sex-linked …
