Arabidopsis lyrata Assembly and Gene Annotation

About Arabidopsis lyrata

Arabidopsis lyrata is a small perennial outcrossing brassica that is distributed within Eastern Asia, Europe and Northwestern America. A close relative of the dicot model, Arabidopsis thaliana, Arabidopsis lyrata has a genome size that is 1.5x larger with a haploid chromosome number of eight.

Assembly

The genome was assembled by the Stanford Human Genome Center with assistance from the A. lyrata community. Sequencing followed a whole genome shotgun strategy and achieved an average genome coverage of 8x. The 206.7 Mb Araly1 assembly contains 695 nuclear scaffolds.

Annotation

The genome was annotated by the U.S. Department of Energy Joint Genome Institute (JGI) using collaborator-submitted RNA-seq data, custom JGI analyses, and the automated JGI Annotation Pipeline and is predicted to have approximately 32,670 genes.
