Status

v2.0 (May 2010)

The assembly release version 2.0 is an Arachne assembly that was improved based on markers of the genetic linkage map that were sequenced and aligned to the genome and is now in 56 main genome scaffolds. Roughly half of the genome is contained in 5 scaffolds all at least 5.9 MB in length.

v.1.0 (August 2007)

The assembly release version 1.0 of whole genome shotgun reads was constructed with the JGI assembler, Jazz, using paired end sequencing reads at a coverage of ~7.11X. After trimming for vector and quality, 602,555 reads assembled into 395 main genome scaffolds totaling 73.4 MB. Roughly half of the genome is contained in 12 scaffolds all at least 1.99 MB in length.

v2.0 (May 2010)

Annotation 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 13,903 genes were structurally and functionally annotated.

v1.0 (August 2007)

The v1.0 annotation was produced by the JGI Annotation Pipeline, using a variety of homology-based and ab initio gene predictors. After filtering for EST support, completeness and homology support, a total of 10,316 genes were structurally and functionally annotated.
