Info • Macrocystis pyrifera CI_03 v1.0

Status

[October 2022] The genome and transcriptome sequences of Macrocystis pyrifera CI_03 were not determined by the Joint Genome Institute (JGI). The genome was sequenced with PacBio, and then assembled by Sergey Nuzhdin's lab at the University of Southern California. Published RNAseq datasets from NCBI (Accession numbers: SRR5026366, SRR5026588, SRR5026590, SRR5026591, SRR5026593, SRR5026594, SRR3544557, SRR3615022) were assembled with Trinity. In addition, a second RNAseq dataset of the gametophyte development stages was provided by Filipe Alberto's lab and assembled with Trinity. Subsequently, the JGI Annotation Pipeline was used to generate structural and functional annotations.
