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 …

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 …

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 …

Sex chromosomes are widespread in species with separate sexes. They have evolved many
times independently and display a truly remarkable diversity. New sequencing technologies …

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 …

Sex chromosomes have evolved hundreds of times across the flowering plant tree of life;
their recent origins in some members of this clade can shed light on the early consequences …

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 …
