Cannabis sativa cultivar Chemdawg (marijuana)

This genome was sequenced by Medicinal Genomics (located in the Netherlands). It was sequenced with one lane of the Illumina HiSeq (2x100) platform and assembled with CLCbio’s workbench. Additional information about the assembly and genome may be found: http://www.medicinalgenomics.com/the-c-sativa-genome/

Cannabis is a member of the plant order Rosales. Of sequenced genomes in that order, the peach genome is a fantastic comparator. The reason for this is due to its high-quality sequence and assembly, along with its genomic evolutionary history that does not contain any subsequent whole genome duplication event to the eudicot paleohexaploidy shared by nearly all dicots (at least the eurosids and the astrids). As such, its genome structure is probably very similar the common ancestor of order Rosales, and perhaps the eudicots as a whole. This likely ancestral state of its genome makes it quite suitable for generating a pseudoassembly of highly fractured, low quality genome assemblies such as this Cannabis genome. CoGe's tool SynMap has an algorithm to tile contigs along any other "reference" genome in CoGe.

This shows the Cannabis genome sequence contains nearly the entire gene content of Peach.
