Wallaby assembly and gene annotation


This is the first release of the 2x wallaby (Macropus eugenii) genome assembly Meug_1.0 (GCA_000004035.1). The genome was sequenced by the Human Genome Sequencing Center Baylor College of Medicine which, along with the Australian Genome Research Facility Ltd., is part of the Tammar Wallaby Genome Sequencing Consortium.

The N50 size is the length such that 50% of the assembled genome lies in blocks of the N50 size or longer. For the contigs in the assembly the N50 size is 2.5 kb and for the scaffolds 14.5 kb. The total length of all of the contigs in the assembly is 2.55 Gb with the assembly spanning 2.78 Gb.

The genome assembly represented here corresponds to GenBank Assembly ID GCA_000004035.1

Gene annotation

Annotation of the genome was completed using the low coverage gene-build method. During this process, some scaffolds were used to construct larger "gene-scaffolds". There are 10,257 such gene-scaffolds, with identifiers of the form "GeneScaffold_1".

The gene set for wallaby contains a total of 17,877 genes, of which 15,290 are protein coding.

Golden Path Length

The golden path is the length of the reference assembly. It consists of the sum of all top-level sequences in the seq_region table, omitting any redundant regions such as haplotypes and PARs (pseudoautosomal regions).

Gene counts

Coding genes

Genes and/or transcript that contains an open reading frame (ORF).

Non coding genes1,472
Small non coding genes

Small non coding genes are usually fewer than 200 bases long. They may be transcribed but are not translated. In Ensembl, genes with the following biotypes are classed as small non coding genes: miRNA, miscRNA, rRNA, scRNA, snlRNA, snoRNA, snRNA, and also the pseudogenic form of these biotypes. The majority of the small non coding genes in Ensembl are annotated automatically by our ncRNA pipeline. Please note that tRNAs are annotated separately using tRNAscan. tRNAs are included as 'simple fetaures', not genes, because they are not annotated using aligned sequence evidence.

Misc non coding genes42

A pseudogene shares an evolutionary history with a functional protein-coding gene but it has been mutated through evolution to contain frameshift and/or stop codon(s) that disrupt the open reading frame.

Gene transcriptsNucleotide sequence resulting from the transcription of the genomic DNA to mRNA. One gene can have different transcripts or splice variants resulting from the alternative splicing of different exons in genes.18,310
