Figure 9.

Gene ontology classifications for transcripts elevated at different time points after the initiation of differentiation from stumpy forms to procyclic forms. Up-regulated genes at each time point were classified according to the 'molecular function' gene ontology and the frequency of members of each classification plotted as a fraction of the total number of regulated genes. The source data for genes up- and down- regulated during differentiation and at transient windows throughout the differentiation programme are provided in Additional file 8.
