Status

v.2.0 (November 16, 2006): This Phaeodactylum tricornutum 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 Phaeodactylum_tricornutum_v2.051706 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 Phatr2 annotation.

Summary statistics for the v2.0 release (Phatr2), with comparsion to the v1.0 release (Phatr1), are below:
