- Bill Ebersold
[posted August 6, 2009]
We have learned from Paul Levine that Bill Ebersold, one of the pioneers of genetics in C. reinhardtii, died on July 25. The following notice was posted on the UCLA web site:
07/28/2009 - PROFESSOR WILBUR T. EBERSOLD PASSES AWAY
Former friend and colleague "Bill" Wilbur T. Ebersold passed away Saturday 25 July after an extended illness. Bill was the second chair of Biology, following the merger of Zoology and Botany. Soon after Bill stepped down as Chair in the late 1970s, he suffered a major stroke, but returned to UCLA, retiring in 1991. He received his Ph. D. from Stanford University and did post doctoral studies at Dartmouth and Harvard before coming to UCLA. His research focused on Chlamydomonas genetics. Although Bill has been away from UCLA for a long time he will be missed.
There will be a memorial service for Bill on 14 August at Forest Lawn Hollywood Hills at the "Old North Church" at 2:30 PM. The family requests that in lieu of flowers contributions be made to the Department of Ecology and Evolutionary Biology at UCLA for the support of graduate students. Information may be found at http://www.eeb.ucla.edu/giving/. regarding a memorial contribution in memory of Bill.
- GreenGenie2
[posted June 12, 2009]
From Susan Dutcher:
The Chlamydomonas gene-finder, GreenGenie2, is now online. It was trained on Chlamydomonas EST sequences and shows excellent short-sequence prediction accuracy. Input sequences are limited to 150Kb. It has several new user-friendly features. (Kwan, Kulp, Dutcher, and Stormo, (2009) BMC Genomics 10: 210).
-Exon highlighting and underlining (for black and white printing)
-Translated amino acid sequence in output
-Optional automated generation of JGI custom track code
-Output sequences are searchable across line breaks in-browser
It is available at http://bifrost.wustl.edu/GreenGenie2
- Companion web site for The Chlamydomonas Sourcebook, Second Edition
[updated April 24, 2009]
Those of you who have the new Chlamydomonas Sourcebook, second edition, are probably aware that the "companion web site" for this volume at Elsevier is still a garbled mess. We've been trying since early December to get this fixed, without success. George Witman and I have therefore created an alternative site at http://www.chlamy.org/companion.html that provides descriptions and links for two methods files for volume 2, and the many terrific videos that accompany volume 3.
Please let me know if you have problems viewing or downloading these files: chlamy@duke.edu

- Updates to the Chlamydomonas Resource Center
[posted January 15, 2009]
A new on-line ordering form and secure on-line payment site are now working. A shopping cart-based order system is under construction and should be up soon.
Among the new acquisitions are the artificial miRNA plasmids recently described by Molnar et al. [PMID: 19054357]. See the plasmid list for additional information.
- Chlamydomonas Sourcebook
[posted December 8, 2008]
The Chlamydomonas Sourcebook, Second Edition, is now available for purchase from Elsevier Science and Technology. From the home page, a search for "Chlamydomonas" will retrieve the information on how to order. The three volumes can be purchased individually, or as a set.

The Joint Genome Institute is pleased to announce the public release of
the Volvox carteri genome. Our annotation includes the 1265
scaffolds and 138 Mbp of the 8.1x assembly and we predicted 15,544
genes, with the following average properties:
Gene length 5269 nt
Transcript length 1833 nt
Protein length 558 aa
Exon frequency 7.78 exons per gene
Exon length 235.59 nt
Intron length 508.53 nt
Gene density 112.64 genes/Mbp scaffold
The genes were predicted by the following methods:
Known genes 143 (1%)
Homology-based 3,645 (23%)
ab initio 11,756 (76%)
Total models 15,544
The genes were validated by the following evidence:
ESTs 5,356 (34%)
Swissprot hit 9,944 (64%)
Pfam hit 2,733 (18%)
manually curated 844 (0.5%)
The annotation may be browsed, searched and downloaded at the /Volvox
carteri/ (database name Volca1) portal:

- Ostreococcus draft genome sequence
[posted July 22, 2006]
JGI has released draft versions of the Ostreococcus tauri and lucimarinus genomes:
http://genome.jgi-psf.org/Ost9901_3/Ost9901_3.home.html
http://genome.jgi-psf.org/Ostta4/Ostta4.home.html
From the web site above: "Ostreococcus belongs to the Prasinophyceae, an early-diverging class within the green plant lineage, and is reported as a globally abundant, single-celled alga thriving in the upper (illuminated) water column of the oceans. The most striking feature of O. tauri and related species is their minimal cellular organization: a naked, nearly 1-micron cell, lacking flagella, with a single chloroplast and mitochondrion."
- Release of version 3.0 of the C. reinhardtii genome sequence

Dear Colleagues,
I am pleased to announce that JGI has completed automated annotation of Chlamydomonas reinhardtii v3.0.
15,256 gene models have been predicted and annotated; over 2,000 curated annotations have been transferred from the previous release.
Genome Portal is now publicly available from www.jgi.doe.gov/chlamy

- Chlamydomonas flagellar proteome database
[posted August 12, 2005, from George Witman]
The flagellar proteome database described by Pazour et al, J. Cell Biol. 170, 103-113 (2005) is now on line at http://labs.umassmed.edu/chlamyfp.
The website has a sortable list of all proteins identified in C. reinhardtii flagellar membrane, matrix and axonemal fractions by mass spectrometry. The list can be searched by Interpro descriptions or for transmembrane helices, etc. The site also has a list of previously known flagellar proteins, data on the induction of flagellar genes by deflagellation, BLAST comparisons and other data on homologues, and the ability to search for proteins found in a particular slice of a 1-D SDS gel.
- Molecular Markers for Map-Based Cloning
[posted August 12, 2005, from David Stern]
One of the goals of the current Chlamydomonas genome project is to saturate the genome with molecular markers, which can be use for map-based cloning or other genetic studies. Thanks to earlier work from the Mets, Dutcher and Silflow/Lefebvre laboratories, supplemented by our own, we compiled a list of 526 markers as recently published in Plant Physiology (http://www.plantphysiol.org/cgi/content/abstract/137/2/557)
We are now pleased to provide with the community with a large number of additional markers, giving an estimated total of 9,300. These are of several types, but all are based on PCR. Each marker is linked to a specific location on a genome scaffold, and primer sequences and annealing conditions are given. A representative number of each marker type has been tested, leading to the estimate of 9,300 markers which will perform correctly in mapping experiments using S1-D2 polymorphisms with laboratory strains.
Please see the web page for further information. We hope the community will take advantage of these resources to further our understanding of Chlamydomonas biology.
- Version 2 Microarray
[posted March 3, 2005]
The version 2 microarray is ready for shipping. This array consists of about 10,000 oligonucleotides, each approximately 70 nucleotides long. Each of the oligonucleotide should represent a unique gene. The set of 10,000 oligonucleotides was printed twice on the same slide (so each slide has duplicates). The oligonucleotides were prepared by Integrated DNA Technologies and their quality was checked by mass spectroscopy. The set of 'unigenes sequences' used for oligonucleotide generation was developed by Monica Jain and Stephan Eberhard in my laboratory. We will also provide information describing potentially empty and weak spots (there were very few of these in our initial examination). While the .gal file with a gene identifier and the sequence of the oligonucleotide used at each position on the array will be available, it may take a little more time to link whatever annotation is available to the individual spots (it will be a priority over the next month or two). We will also put a protocol onto the web site that we used for the hybridizations and will try to address any technical questions that you might have concerning the array. A manuscript describing how the unigene set was chosen and oligonucleotide design is in preparation, and we will make it available to people using the array as soon as possible.
The cost is $100 per slide. Please send orders to:
