About the Opossum genome

Assembly

Opossum This site presents the first preliminary genome assembly (version 0.5) of the gray short-tailed opossum.

The assembly, from the Broad Institute, has a base coverage of approximately 7.19X, constructed from 19348 supercontigs, having N50 length 4047488. The total contig length is 3492108230, spanning 3559101070 bases (including gaps)

Annotation

The gene set for Opossum was built using a modified version of the standard Ensembl genebuild pipeline. The species-specific sequence resources (opossum cDNA and protein) are very limited, so the vast majority of gene models are based on genewise alignments of proteins from other species. Most of the proteins being aligned were from species genetically distant to opossum. To improve the accuracy of models generated from these proteins, the genewise alignments were made to stretches of genomic sequence rather than to 'miniseqs'. Opossum and human cDNAs were aligned and used to add UTRs to the genewise predictions where possible. The gene models were assessed by generating sets of potential orthologs to genes from other mammalian species. Potentially missing predictions and partial gene predictions were identified by examining the orthologs, and exonerate used to build new gene models for these based on the human ortholog peptide sequence.
