the website is back up and running. If you find any problems, please let me know.
Colletotrichum.org will be intermittently unavailable beginning tomorrow (Feb 23) until early next week while we move the server hardware to a new building and reconfigure the network.
I just added a forum to the website. Now, in addition to the blog, registered users can post messages and reply to other people’s messages using the forums.Â This format should be more convenient for people who want to ask questions and start discussions on the web site.
The genome of Colletotrichum graminicola will be sequenced in 2007. The project is supported by the National Research Initiative of the USDA Cooperative State Research, Education and Extension Service, (grant number 2007-35600-17829). The principal investigators of the grant are Lisa Vaillancourt (University of Kentucky), Li-Jun Ma (the Broad Institute of MIT and Harvard), Martin Dickman (Institute for Plant Genomics and Biotechnology, Texas A&M University), Jeffrey Osborn (University of Kentucky), and Michael Thon (Texas A&M University).
The objectives of the project are:
- Produce and release to the public sequence reads from 8X shotgun coverage of the genome of C. graminicola strain M1.001.
- Construct a high quality draft assembly and annotation, and make this accessible to the public via the Broad Institute’s Fungal Genomics website.
- An optical map and an EST resource will be developed to further validate and enhance these data. The map and the EST data will also be publicly released.
- Lay the groundwork for a comparative genomics resource at Texas A&M University focused on understanding the evolutionary and functional relationships among hemibiotrophy and other plant-parasitic fungal lifestyles.
- Develop an educational unit for Appalachian high school teachers and students that provides a solid understanding of genomics and bioinformatics and how basic genomics research contributes to the advancement of the science of agriculture.
Overview of Sequencing: Genome Seqencing: Our goal is to produce a total of ~615,000 reads representing ~8x coverage in Q20 bases and ~64x in physical coverage. Two plasmid libraries with insert sizes of 4 and 10 kb will be used to provide the majority of sequence coverage. Fosmids, which contain 40kb average inserts from randomly sheared genomic DNA, provide long-range linking information that allows large scaffold sizes to be achieved.The Broadâ€™s assembly program, Arachne, will be used to assemble the Colletotrichum genome sequence. To provide an independent view of the genome and a measure of the quality of the genome assembly, an optical map will be commissioned from OpGen Inc. (Madison, WI, http://www.opgen.com/default.aspx). The quality of the Broad assembly will be assessed by comparing the predicted restriction fragment lengths from the assembled genome with the observed fragment lengths in the optical map. The map also provides a means to anchor sequence to the genome, adding order and orientation to the sequence contigs where there previously was none.The Calhoun whole genome analysis system will be used to identify repeat features, call genes using a variety of gene prediction tools, assign functional annotation to genes, predicts protein domains, and provides access to genome annotation data and support various analyses.EST Sequencing: EST sequences developed at the University of Kentucky will be used to train the gene prediction algorithm. We propose to sequence both ends of a total of 15,000 clones. The sequences will be collated into unigene sets with the aid of stackPACK. BLAST and conserved domain and Prosite signature motif searches will provide information about possible functional classes.

We are pleased to announce that the Colletotrichum Workshop will be held in conjunction with the Fungal Genetics Conference at the Asilomar Conference Grounds, Pacific Grove California on Sunday, March 25 2007.
Colletotrichum Meeting Organizers:
- Lisa Vaillancourt, University of Kentucky, USA (email)
- Dov Prusky, Agricultural Research Organization, The Volcani Center, Israel
Tentative Schedule: (please follow this link)
Time and Place: The meeting is scheduled for 9:00 AM to 5:00 PM at the Asilomar conference center. Details will be announced during the Fungal Genetics Conference.
Housing: Since the meeting will take the whole day on March 25th, many people have elected to book a room for an extra night at the Asilomar Conference Grounds. Lynn Epstein has coordinated the booking for most people and it may be too late to add additional people. If you need to stay an extra night, please contact Lisa Vaillancourt of Lynn Epstein for more information.
Posters: We would like to compile a list of posters and talks that will be presented during the fungal genetics conference. If you are planning a presenetation involving Colletotrichum during the meeting, please send your title to Lisa Vaillancourt and we can incude it in the list.
