Info • Scenedesmus obliquus UTEX 393 v2.0

Status

[August 2020] The Scenedesmus obliquus strain UTEX 393 genome assembly was constructed by merging multiple assemblies that originated from three independent Illumina assemblies (NCBI GCA_900108755.1; an unpublished dataset provided by D.R. Nelson from New York University Abu Dhabi; JGI CSP Proposal Id: 503423) and one PacBio assembly (Reads from JGI CSP Proposal Id: 503423). Merging of the assemblies was performed by Dr. Zaid McKie-Krisberg at Brooklyn College of the City University of New York. The gene models were predicted and annotated by the Joint Genome Institute (JGI) Annotation Pipeline. Note that scaffold_72 and scaffold_154 are predicted to be the chloroplast and mitochondrial genomes, respectively.
