Info • Lobaria pulmonaria Scotland extracted metagenome v1.0


[March 2018] Assembly v1 is a minimal draft assembly extracted from a lichen metagenome by aligning the reads with the reference mycobiont genome. The aligned Illumina gDNAs were assembled with Velvet and then AllPathsLG. The mitochondrial assembly is available on the Download page.

Annotation v1 is a draft annotation, using an extracted metatranscriptome, the reference mycobiont transcriptome, and the JGI Annotation Pipeline v1.10. The metatranscriptome was extracted by aligning the Illumina reads with the extracted mycobiont genome. The metatranscriptome and the reference transcriptome were each assemblied separately with Trinity.
