Status

Assembly

v2.0 (June 2010) The assembly release version 2.0 is an Arachne assembly that was improved with finishing reads and gap closure. The v2.0 assembly is now in 15 scaffolds at least 10 of which represent nearly complete chromosomes. Roughly half of the genome is contained in 6 scaffolds all at least 2.6 Mb in length.

v1.0 (June 2009) The assembly release version 1.0 of whole shotgun reads was constructed with the Arachne assembler using paired end sequencing reads at a coverage of 8.23x.

Annotation

v2.0 (June 2010) of the v2.0 assembly was produced by the JGI Annotation Pipeline, using a variety of homology-based and ab initio gene predictors. The v1.0 gene catalog along with its manual curations was mapped to the v2.0 assembly and included in filtering. After filtering for EST support, completeness and homology support, a total of 13,405 genes were structurally and functionally annotated.

v1.0 (June 2009) of the v1.0 assembly was produced by the JGI Annotation Pipeline, using a variety of homology-based and ab initio gene predictors. After filtering for homology support, a total of 12,270 genes were structurally and functionally annotated.
