I.14 Report from the International Committee of Nomenclature and Symbolization of Barley Genes.

A. Hagberg and D. von Wettstein, members of the International Committee of Nomenclature and Symbolization, prepared "Recommendations by the International Committee for Assigning Barley Gene Symbols", the socalled "Document 3" for publication in BGN, Vol. 1 with the necessary corrections to be made by the chairman of the committee (T. Tsuchiya) based on the comments from other members of the Committee. "Document 3" consists of the following three sections:

1. The Recommended Rules for Symbolization reported by the International Committee on Genetic Symbols and Nomenclature, 1957, along with the (following) amendments applying to Barley Gene Nomenclature and Symbolization.

2. The procedure for requesting a symbol for a new mutant.

3. The list of coordinators.

Some parts of Section (1) and the most of Section (2) were taken from the "Proposals Concerning Genetic and Cytological Symbolization and Maintenance of World Collections of Seed Stocks of Barley" (BGN. 1:3-10) and the "Comments for the Proposal from Aberdeen Meeting" by A. Hagberg and D. von Wettstein (BGN 1:11-14).

None of the members responded to that proposal at the time of publication of BGN, Vol. 1. Therefore, the chairman understood that the other members needed more time to review it and did not publish it in BGN, Vol. 1.

In August 1971, the members of Barley Genetics Committee of the American Barley Research Workers' Conference met in Bozeman, Montana, U.S.A. for further discussion and improvement of the proposal concerning the "Nomenclature and Symbolization of Barley Genes". A new proposal was prepared by the American Group after the suggestions and comments given by Hagberg and Wettstein (BGN 1:11-14) and Takahashi (BGN, 2: 9-10 ) were considered and published in this issue (BGN 2: 10-15). Informal discussions among three members, J. G. Moseman, A. Hagberg, and D. von Wettstein indicated that the principles and most of the parts of the proposals are agreeable to each other. Consequently, the chairman of the International Committee has made some changes in "Document 3" based on the comments given by G. A. Wiebe, J. G. Moseman and T. Tsuchiya, and the copy was sent to all members of the International Committee for further review.

The proposed final form of "Recommendations by the International Committee for the Nomenclature and Symbolization of Barley Genes" to be recommended for adoption at the International Barley Genetics Symposium to be held in 1974 or 1975 is printed in this issue pp. 11-15.

The following procedure for requesting a symbol for a new mutant should be followed:

1. Submit to the chairman of the International Committee for assigning Barley Gene Symbols the following information concerning the new mutant.
a. The name of the variety, hybrid selection, or stock in which the mutant originally occurred.
b. The source of the mutation (spontaneous origin, induction with a specific mutagenic agent, etc.)
c. Detailed description of the mutant phenotype including where appropriate, morphological, physiological, and cytological details (see for detail, BGN 1: 6-7). Photographs, slides, and/or line drawings illustrating the mutant phenotype should be accompanied for application of gene symbols. Color photographs and slides should be submitted for chlorophyll and other color mutants except albino mutants. Line drawings should be submitted where photographs do not adequately portray the mutant phenotype
d. Inheritance data.

2. Submit a suggested symbol and justification for its use in accordance with recommended rules of symbolization.

3. Send seed samples (50 kernels or more) of the mutant and the original variety in which it occurred to the Genetic Stock Center, Department of Agronomy, Colorado State University, Fort Collins, Colorado 80521, U.S.A. (Attention: Dr. T. Tsuchiya).

4. After the assignment of a permanent gene symbol by the committee, the mutant stock will be assigned a Barley Genetic Stock (BGS) number.

5. Two copies of the reprints in which data regarding a new gene are published should be sent to the Genetic Stock Center.

Coordinators for the various chromosomes, for special gene collections and for various chromosomal variations are necessary for the advancement of barley genetics. These coordinators should be appointed by the Committee on Genetic Marker Stocks, Nomenclature and Symbolization of the International Barley Genetics Symposium. Workers studying special gene collections are encouraged to act as coordinators during the period that they have an interest in such a collection. The chairman of the Committee on Genetic Marker Stocks, Nomenclature and Symbolization of the International Barley Genetics Symposium should coordinate the appointments of coordinators for special gene collections. He should publish a list of the active coordinators in each issue of the Barley Genetics Newsletter.

The duties and responsibilities of the coordinators should be:

1. Maintain current information concerning their area and serve as a source of information concerning that area.

2. Prepare an annual report for the Barley Genetics Newletter.

3. Maintain world collections of genetic and cytological seed stocks.

4. Perform, and encourage and support others to perform special work necessary to the advancement of barley genetics.

5. If a coordinator feels that he cannot meet these and other special duties and responsibilities as they develop he should notify the Chairman of the Committee on Genetic Marker Stocks, Nomenclature and Symbolization of the International Barley Genetics Symposium so that another coordinator can be appointed.

We have received some comments on gene symbolization this year (see this issue). We also expect other comments or suggestions from people interested in barley genetics after reading this proposal. We would like to have a final form to be presented at the next International Barley Genetics Symposium to be held in Germany. Therefore, the International Committee for Nomenclature and Symbolization requests constructive suggestions and comments which should be sent to T. Tsuchiya or other members of the Committee.

To avoid chaos in future barley genetics research the question of nomenclature is very important and equally important is that the rules adopted are followed. Different groups naturally have different systems on material being genetically and cytogenetically analysed as "work shop names or tags" on genes, mutants, etc. If these preliminary names are published it has to be clearly stated which group or collection these names apply. At present it is alarming that different groups who are building up new mutant gene collections are assigning to their mutants the same symbols which describe already existing mutants. This must be avoided. Appropriate allele tests and checking on the identity of the assigned loci and registration by the coordinators should be obligatory before publication. A preliminary designation should be published only in exceptional cases.

Also the chairman of the Committee particularly asks the cooperation of all barley geneticists in the operation of the policy, by following the procedures published in this Report, Information to be given to the Chairman of the Committee regarding the new mutants is easily prepared if barley geneticists use the format used in the Description of Genetic Stocks (BGN 1:103-193; BGN 2:172-200).
