Characteristics of the de novo-assembled B. braunii 779 transcriptome. a Distribution of number of best-hits derived from the genome of various algal species. X- and Y-axis indicate the genome of algal species used and the number of ESTs in B. braunii 779. b Length and c count distribution of the 21,292 annotated ESTs in B. braunii 779. X- and Y-axis indicate the EST length (left panel) and count (right panel) and number of ESTs, respectively. d Ten GO biological process categories associated with the most number of ESTs in the transcriptome of B. braunii 799. e Ten KEGG pathways associated with the most number of ESTs in the transcriptome of B. braunii 799.
