Eragrostis tef Assembly and Gene Annotation

About Eragrostis tef

Eragrostis tef, known as tef or teff, is a small-seeded allotetraploid cereal (2C=2n=4x=40). It is grown as a crop for human consumption in the Horn of Africa and cultivated for hay in countries such as South Africa, Australia, and the USA.

Assembly

The genome of the Tsedey improved variety was assembled by the Tef Improvement Project (https://tef-research.org) at the Institute of Plant Sciences of the University of Bern, Switzerland, with assistance from the Swiss Institute of Bionformatics. A whole-genome shotgun strategy resulted in an average genome coverage of 44x with Illumina short reads and 7x with 454 pyrosequencing. The 672 Mb assembly contains around 14,000 nuclear scaffolds greater than 1000 bp and represents about 87% of the genome size estimated from flow cytometry.

Annotation

Genes were annotated by the Tef Improvement Project using RNA-Seq data, a normalized transcriptome and UniProt monocots in combination with Augustus and SNAP in the Maker pipeline. Currently contains 41,555 protein-coding genes.
