Bigelowiella natans Assembly and Gene Annotation

About Bigelowiella natans CCMP2755

Bigelowiella natans is a species of Chlorarachniophyte alga that is a model organism for the Rhizaria.

Chlorarachniophyte are unicellular marine algae with plastids of secondary endosymbiotic origin. Bigelowiella natans are a key resource for studying the supergroup of mostly unicellular eukaryotes.

Assembly

The nuclear genomes of B. natans is approximately 95 megabase pairs (Mb) in size. The genome was assembled by Joint Genome Institute (JGI) into 3736 contigs which are then assembled into 302 scaffolds. It is estimated to have 3.5% sequence bases in the gap.

Annotation

The genome is gene rich with more than 21,000 predicted protein, 229 genes per Mbp scaffold. The average gene length is ~2800nt with average of 8.9 exon per gene. 86% of the genes have intron. 92%of the gene models have start and stop codons.
