Figure 3

Example of the implementation of a plant anatomy ontology in a graphical interface. Expression values from Arabidopsis are plotted against either a tree (A) or list (B) of anatomical parts. Simple expression values are preferably plotted against a tree which can be expanded/collapsed in a fine-granular way. In this case, the expression value for a given node is the average over all samples within and below that node. In contrast, clustering of the data matrix requires the linearization into a list and the removal of nodes that contain no samples. The above list is derived from the anatomy tree for Arabidopsis, structured according to the generalized tree for dicotyledonous species.
