Status

v3.0 (November 16, 2006): This Thalassiosira pseudonana genome sequence assembly was initially  assembled using the JGI assembler, Jazz, constructed from whole genome shotgun and paired end sequencing reads. That draft assembly was finished by the Stanford Human Genome Center which produced the Thalassiosira_pseudonana_v3.031306 genome assembly reported here. The nuclear genome sequence from the finished assembly was annotated using the JGI Genome Annotation Pipeline and custom analyses, reported here as the Thaps3 annotation.

Summary statistics for the 3.0 release (Thaps3), with comparsion to the previous v1.0 release (thaps1, the previous public release), are below:
