Sex-chrom: a database on plant sex chromosomes

Most angiosperms are hermaphrodite, and only few have separate sexes, either in different flowers  in the same individual (monoecy) or different flowers in distinct individuals (dioecy). Among dioecious plants some have environmental control of sex determination. Some others have genetic control of sex determination, but without cytologically differentiated sex chromosomes and a minority do have sex chromosomes. Conversely, in animals, separate sexes and heteromorphic chromosomes, are common. The low frequency and scattered taxonomic distribution suggest that sex chromosomes have evolved repeatedly and quite recently in plants.


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.
