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.

Scalable Vector Graphics: a graphics format suitable for import into many graphics programs e. g. Adobe, Corel, Inkscape...
"Comma-separated values": a data format suitable for import into most spreadsheet and database programs. The column separator used here is the semicolon. Character coding is UTF-8.
A format commonly used in phylogenetics to represent a tree structure as nested brackets.
"American standard code for information interchange": the name can be used almost synonymously with "plain text", also including a very limited graphics capability.
A format commonly used to store alignments along with meta-information, e. g. analysis parameters. Used e. g. by PAUP* and MrBayes.
Probably due to its simplicity the most frequently used sequence or alignment format ever designed. Used by a vast majority of bioinformatics programs and packages.
Widely used alignment format. Required as input by many bioinformatics programs. The interleaved version is exported here. Unfortunately very limited meta-information capabilities.
The alignment format originally used by the GCG Wisconsin bioinformatics package (e. g. Pileup). Still widely used as an alignment format.
The format used by Clustal (and some other programs) to store alignments.

ITS Phylogenetics Tool

As currently delimited, the Brassicaceae comprise 52 tribes, 341 genera, and 3977 species. Of these, 11 genera and 19 species remain to be assigned to tribes. These figures differ substantially from those estimated five years ago, in which 49 tribes, 321 genera, and 3660 species were recognized, of which 20 genera and 34 species were lacking tribal assignment (Al-Shehbaz, 2012).

BrassiBase's phylogenetic visualizations are based on a ”synoptic diagram” of phylogenetic relationships“ presented by Franzke et al. (2011) and continuously updated with most recent findings (e.g. Huang et al., 2016).

BrassiBase provides the opportunity to run your own “ITS barcode sequence” (internal transcribed spacers 1 and 2 of nuclear ribosomal DNA, including the 5.8 S gene) as query against the database.

A putative phylogenetic position will be indicated. However, the presented results cannot replace any detailed phylogenetic analysis! This tool is intended only to provide reference points for subsequent own analyses. It should be kept in mind that the presented trees are based on ITS sequences only, and they are also not constraint in their topology by evidence given from other phylogenetic studies. For the pros and cons of ITS sequences as marker in phylogenetic studies please refer to Kiefer et al. (2014).

Sequences and Alignments

All sequences used in creating the reference alignments for BrassiBase were taken from GenBank. Alignments were initially created using MUSCLE and edited extensively in a subsequent step. All alignments were checked for plausibility using phylogenetic analyses (using Maximum Likelihood methods). Alignments are available for the different Brassicaceae tribes on the corresponding summary pages (use search box to the right, e.g.).
