The Gracilaria domingensis SP 400837 genome sequence and gene models were not determined by the Joint Genome Institute (JGI), but were downloaded from NCBI on March 2, 2023. In order to ensure this genome is comparable to those sequenced by the JGI, we applied filters to remove if present: 1) transposable elements, 2) pseudogenes, 3) alternative transcripts and overlapping models, 4) alleles on secondary scaffolds and 5) unsupported short models. This resulted in the removal of 1,580 models and the generation of the FilteredModels1 (GeneCatalog) gene track. All published models are available in the ExternalModels track. Please note that this copy of the genome is not maintained by NCBI and is therefore not automatically updated. In order to allow comparative analyses with other algal genomes sequenced by the JGI, a copy of this genome is incorporated into PhycoCosm. The JGI Annotation Pipeline was used to add functional annotation to the genes.

Gracilaria domingensis isolate:SP 400837

Gracilaria domingensis is a red alga highly dispersed along the intertidal zones of Central and South America. The cell wall of G. domingensis contains agar, a polysaccharide mixture used in a wide variety of industrial products, such as food, medicines, cosmetics, chemicals, textile, among others. This genome analysis also contributes to understanding the little known universe of Rhodophyta genomics. This group is a huge source not only of useful metabolites but also of new protein domains and families with evolutionary importance, for plants and also for all eukaryotes.
