The search field accepts scientific plant names, i. e. names of genera or Brassicaceae tribes.

Examples:

  • Camelineae — will find information about all member genera of tribe Camelineae.
  • Arabidopsis — will find information about the genus Arabidopsis.

After having typed 3 characters, you'll be provided with suggestions from the database.

Taxonomy Tool

The Taxonomy Tool provides the option to search for any genus and its respective tribal placement, as a result the respective taxonomic information is given. Additionally some selected taxonomic literature und links to the taxonomic databases IPNI and TROPICOS are provided. If available, additional material like images is provided. For many genera detailed genus descriptions are also available. Missing descriptions are continuously generated and added to the database. As a link to the Phylogenetic Placement Tool the respective tribe-wide alignment of ITS sequences (internal transcribed spacers 1 and 2 of nuclear ribosomal DNA, including the 5.8 S gene) can also be displayed and downloaded.

Details

    In the most recent overview, the mustard family comprises 3660 species classified in 321 genera (Al-Shehbaz 2012). The family-wide evolutionary framework currently consists of 49 tribes defined as monophyletic lineages. Only 20 genera have not yet been assigned to one of these tribes (Al-Shehbaz 2012), in most cases because plant material suitable for molecular systematic approaches is not readily available.

    The mustard family belongs to the order Brassicales (core eudicots, Rosids) with three families grouped to “core Brassicales” (e.g., Beilstein et al. 2010): Brassicaceae, Cleomaceae, Capparaceae (4440 species in total) and additional 14 plant families with much lower total species number (245 species in total, Stevens 2001).

    In the past, systematics, taxonomy and evolution of the Brassicaceae have long been controversial because the generic boundaries are often poorly delimited and attempts to group species diversity at higher order and combining genera to so-called tribes resulted in various artificial concepts. These difficulties resulted in a lack of agreement on the number and boundaries of tribes and genera and gave rise to several contradicting classification systems which have been proposed during the past two centuries (for review refer to Warwick et al. 2010). As an important consequence of this past taxonomic history there is a major lack in comprehensive and easily accessible information on tribal and generic placement.
