From the Editor:

Greetings to the TGC membership! This is the fourth volume from your present Managing Editor and the first for my new TGC assistant Dolly Cummings. Dolly has been invaluable in all phases of the TGC operation and you would not be reading this if not for her stellar efforts. I do want to thank John Petti and Gail Somodi who so ably assisted this effort in the past. My contact information is the same as last year except for a small change in my email:

We are back to a September mailing and hope to keep on this schedule in the future. Since I started as Managing Editor, I have asked for tomato researchers to clear the naming of genes and gene symbols through the Tomato Genetics Cooperative. Roger Chetelat as chair of the gene list committee can then easily insure that the nomenclature rules are properly followed. In this volume we finally have officially named two genes, both for TYLCV resistance (Ty-2 and Ty-3). I hope this will be the start of a trend. Also note that Volume 56 includes figures in color, a first for the ever-improving TGC!

One of my major TGC objectives over the past several years has been to have all the TGC volumes electronically available on line and searchable by keyword. This has proven to be a rather involved task, but we are making progress. By the time you read this all volumes should be available on line in both .pdf and .html formats (see our website http://tgc.ifas.ufl.edu/ click Online Volumes). All volumes are not yet keyword searchable but we hope they will be in the not too distant future. The volumes that are presently keyword searchable are listed on the website.

Thank you to all who sent in reports this year. Please consider sending reports for future volumes as it is the lifeblood of the TGC. Reports on varietal releases and on crops closely related to tomato are encouraged. Special thanks to Iris Peralta and colleagues who provided our feature article on tomato nomenclature. Some are using Lycopersicon and some are using Solanum in the literature and this article may help you decide which system you want to use.

If you have a change in your contact information please send me an email so we can keep our records up to date and keep you abreast of the latest from the TGC. Best wishes in your endeavors for 2006-2007.

Managing Editor

 

UPCOMING MEETINGS

GRANT OPPORTUNITY

Request for Proposals for Tomato Germplasm Evaluation

Funding is expected to be available again in fiscal year 2007 for evaluation of tomato germplasm. Proposals must be submitted through the Crop Germplasm Committee (CGC). All proposals will be evaluated according to the national need for evaluation data, the likelihood of success, and the likelihood that the data will be entered into GRIN and shared with the user community. Evaluation priorities established by the CGC (Table 1) will provide review criteria. When all other factors are equal, preference for funding will be given to supporting those proposals forwarded by CGCs that have not received prior funding. Proposals will be reviewed by the CGC and forwarded to the USDA for consideration. Proposals Must be returned to the CGC Chair by October 27 so that reviews and rankings, can be forwarded to the USDA in Beltsville by November 17, 2006.

Because of limited funds, the USDA cannot support all proposals submitted. Consequently, please be very frugal in your request for funds. In recent years, the USDA has capped budget allocations in the range of $15,000-$18,000 per project annually.

The proposal format is outlined below. Please submit proposals electronically as a PDF file to David Francis, CGC Chair, francis.77@osu.edu.

Project title and name, title of evaluators.

Significance of the proposal to U.S. agriculture.

Outline of specific research to be conducted including the time frame involved – include the number of accessions to be evaluated.

Funding requested, broken down item by item. Budgets should follow USDA form ARS454 as funding will be in the form of a specific cooperative agreement. No overhead charges are permitted.

Personnel:

A. What type of personnel will perform the research (e.g. ARS, State, or industry scientist; postdoc; grad student, or other temporary help).

B. Where will personnel work and under whose supervision.

Approximate resources contributed to the project by the cooperating institution (e.g. facilities, equipment, and funds for salaries).
