GO term enrichment analysis. GO term enrichment for each cell type specific gene list was analysed using topGO [60] and GO terms with statistically significant enrichment were examined. Since GO terms are organized hierarchically, the full list (see Additional file 3) contains many hierarchically related GO terms. Here we show hierarchy-representative GO terms that are enriched in each set of cell-type specific genes in the GO categories Biological Process (a), Molecular Function (b) and Cellular Component (c) Enrichment scores for cup, stalk, spore, and vegetative cell specific genes are presented as green, blue, red and amber bars, respectively. Single, double and triple asterisks signify p-values smaller than 0.01, 10− 4 and 10− 10, respectively. Numbers between parentheses represent the total numbers of genes annotated with each GO term in the current dataset
