Sex chromosomes have evolved from a pair of autosomes and
play a key role in genetically-controlled sex determination. Plants
possessing sex chromosomes give us interesting insight into the evolution
of sex chromosomes through the species, because they are evolutionarily
young as compared with those of animals.
In this database you can search for information regarding
plant sex chromosomes in an easily-accessible way. Besides general
information about sex chromosomes, such as their type and morphology, the
database contains advanced information about the genetic elements present
on sex chromosomes and contributing to the sex determination and evolution
of this phenomena.
We ask for the contribution of the users of
the database by reporting new or overlooked counts of
sex-chromosomes, as well as errors.
You can use the search box above to start
looking for genus or species with sex chromosomes. You can also browse
certain model species below, for which more information is available, or in the Browse tab.
