Status

v3.0 (April, 2009): The finished version of Micromonas strain RCC299 v3.0 contains 17 complete chromosomes represented telomere to telomere with a total genome size of 21 Mbp. The chromosomes have been numbered 1-17, largest to smallest. A total of 10,109 gene models were mapped forward from v2.0 to the v3.0 Gene Catalog. The Gene Catalog contains 2519 manually curated gene models as well as models predicted and functionally annotated using the JGI annotation pipeline.

v2.0 (February 15, 2008): The finished version of Micromonas strain RCC299 v2.0 contains 17 chromosomes represented telomere to telomere with 5 gaps and a total genome size of 21 Mbp. The chromosomes have been numbered 1-17, largest to smallest. A total of 10,056 gene models were predicted and functionally annotated using the JGI annotation pipeline.

v1.0: The assembly release version 1.0 of whole genome shotgun reads was constructed with the JGI assembler, Jazz, using paired end sequencing reads at a coverage of 8.9x. After trimming for vector and quality, 274,180 reads assembled into 251 scaffolds totaling 22.3 Mb. Roughly half of the genome is contained in 7 scaffolds all at least 1.4 Mb in length. The v. 1.0 assembly includes a total of 8,007 gene models predicted and functionally annotated using the JGI annotation pipeline.

Movie

  • Paraphysomonas grazing on M. pusilla NOUM17 (mpg): Micromonas are red (a function of chlorophyll fluorescence from their chloroplasts) and can be seen swimming in and out of the field. The greenish particles are the stained food vacuoles of Paraphysomonas, a eukaryotic heterotrophic microbe or “grazer”. The red/orange in the “gut” of Paraphysomonas are ingested Micromonas cells The acidic food vacuole of Paraphysomonas is stained with Lysotracker Green. Contributed by the Worden Lab (H. Moehlig).
