Info • Scenedesmus obliquus EN0004 v1.0

Status

[November 2019] The Scenedesmus obliquus EN0004 genome was sequenced with PacBio, assembled using MECAT with polishing by ARROW, and annotated with the JGI Annotation Pipeline. The transcriptome was sequenced with Illumina and assembled with Trinity. IsoSeq reads sequenced by Pacbio were also used in the annotation. RNASeq and IsoSeq reads were provided by our collaborators and not sequenced by JGI. Mitochondrial and chloroplast genomes were assembled separately and are available in the downloads section.

  • Please note: Using BLAST, unmapped RNA reads and contigs were found to hit Homo sapiens, as well as Proteobacteria (Burkholderia contaminans) and Actinobacteria (Cutibacterium acnes), suggesting that the RNA library was contaminated.
