8 Chlamydomonas reinhardtii is a unicellular green alga which swims with two flagella and has chloroplasts for photosynthesis. The genome is ~100 Mbp and is distributed in 17 chromosomes. The initial goal of the Chlamydomonas reinhardtii genome project is to generate EST sequences, and to date there are over 55,860 Chlamydomonas ESTs in GenBank. Because Chlamydomonas reinhardtii is quite GC rich (~65% G+C), we have begun a pilot project to sequence several BACs in collaboration with Dr. Susan K. Dutcher in the Department of Genetics at Washington University School of Medicine in St. Louis, Missouri. These BAC clones cover a region of ~600 kbp in the Chlamydomonas reinhardtii genome.Dr. Susan K. Dutcher The BAC library prepared by Pete Lefebvre in collaboration with Genome Systems (now IncyteGenomics) is available from IncyteGenomics. Requests for these BACs should be directed to Incyte GenomicsIncyte Genomics A table viewing the BAC clones being sequenced can be viewed at URL: http://www.genome.ou.edu/chlamy_totals.html http://www.genome.ou.edu/chlamy_totals.html In accord with the Bermuda Agreement and NHGRI policy, we are depositing all our human genomic sequence data into the High-Throughput Genomic Sequences (HTGS) division of GenBank as soon as a target large insert clone sequencing project can be assembled into contigs greater than 2 kb. The following BAC clones are being sequenced. This sequence data has been deposited into GenBank, and given accession numbers:High-Throughput Genomic Sequences (HTGS) division of GenBank

9 Status The current draft release, version 2.0 of the Chlamydomonas reinhardtii genome, was generated using the whole genome shotgun strategy, using only data generated here at the JGI. Gene models for this release are currently undergoing manual curation by members of the Chlamydomonas community.This massive effort began during the Chlamydomonas Jamboree, held at the JGI during the week of Dec 8th, 2003. Annotations can be viewed immediately from the protein pages as they become available. To search for genes that have manual annotations, please read the directions on our advanced search page. ReleaseThis assembly was constructed with JAZZ, the JGI assembler, capitalizing on paired-end sequencing reads. After trimming for vector and quality, 1.8 Million reads assembled into 3211 scaffolds totaling 125 Mbp. Roughly half of the genome is contained in 72 scaffolds, all of at least 504 Kb in length. Gene models have been updated using the depth of EST/cDNA information publicly available for C. reinhardtii. Future plansManual review of gene models will continue through the spring, and results will be discussed at a second Jamboree due to be scheduled this coming summer. Stanford will begin finishing the genome later this year. We will update this site once finishing efforts are complete.
