Figure 2. Quality comparison of the 454/EST assembly and the combined final assembly.
A Transcript length distribution of different assemblies. Illumina-based assemblies result in more long transcripts compared to the 454/EST assembly. B The 454/EST assembly results in fewer transcripts and fewer unique transcripts based on BLASTX searches against the nr database compared to Illumina-based assemblies (left y-axis). The combination of datasets results in improved NXX (N25, N50, N75) values for the respective assemblies (right y-axis). Note that Assemblies 1 and 2 are the intermediate assemblies of the stepwise assembly strategy and Assembly 3 is the final assembly including unsupported 454/EST transcripts (see Materials and Methods for details).
