About the taxonomy browser

The taxonomy browser displays the Musa taxonomy as a tree. While taxonomy is better represented as a graph, we use a tree representation to make taxonomy browsing easier. This taxonomy browser is provided "as is" based on passport data provides by curators of the collections. We are aware of some discrepancies relative to the information provided in passport data. Those discrepancies will be removed progressively by manual curation. You will also notice several nodes called "unknown" which groups together accessions that have only been classified up to a certain level.

User interface (mouse/touch screen)

You can use your mouse wheel or your finger and move up and down to zoom in or out. You can drag the tree using your mouse left button or your finger (click/touch, hold, move and release). You can click/tap on an internal tree node in order to collapse or expand its sub-tree. You can also click/tap on the label of a leaf (accession) to access to its passport data (tip: on some web browsers, you can see the target link of the accession if you move your mouse over; that link usually contains the collection code so you can guess the accession collection before clicking).

The button "Reset tree" can be used to restore the original expanded status of each node and zoom out to have an overview of the tree. The "Show/Hide empty nodes" button can be used to display or hide taxonomy nodes that do not contain any accession. For instance, if you are looking at a taxonomy tree of a given collection, that collection may not have accessions for every taxonomy nodes and they will be hidden by default.


The color codes and symbols are explained at the bottom of the page in the "Navigation and legend" section.
