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 …

For decades, satellite DNAs have been the hidden part of genomes. Initially considered as
junk DNA, there is currently an increasing appreciation of the functional significance of …

Today, more than ever, the search for non-trivial sources of biologically active substances is
critical. Plants of the genus Rumex are noteworthy. Plants of this genus stand out for a …

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 …

The nonrecombining regions of animal Y chromosomes are known to undergo genetic
degeneration, but previous work has failed to reveal large-scale gene degeneration on plant …

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 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 …

A minority of angiosperms have male and female flowers separated in distinct individuals
(dioecy), and most dioecious plants do not have cytologically different (heteromorphic) sex …

Heteromorphic sex chromosomes have originated independently in many species, and a
common feature of their evolution is the degeneration of the Y chromosome, characterized …
