IV. 24. Report from the International Committee for Nomenclature and Symbolization of Barley Genes. Fourth International Barley Genetics Symposium, Edinburgh, Scotland, July 22-29, 1981.
The International Committee for Nomenclature and Symbolization met twice during the symposium. The following topics were discussed and decisions made:
1. Barley Genetics Newsletter (BGN) - It was agreed that the Barley Genetics Newsletter should be continued. The committee expressed its appreciation to Dr. T. Tsuchiya, Dr. T. E. Haus, and Dr. R. T. Ramage for their outstanding job of editing and distributing the Newsletter. Tsuchiya agreed to continue as Chairman of the Editorial Committee. Haus and Ramage agreed to continue as members of the committee.
2. Computerized lists of present gene symbols - The offer by D. von Wettstein and R. A. Nilan to develop a computerized list of the published symbols of genes in barley was accepted. They will develop and distribute the list within the next year.
3. System for gene and mutation designation.
A. Present designations for genes and mutations - Most of the present designations should be maintained. However, new designations may be given, based on additional information which indicates that new designations will aid in the identifying of genes and mutations.
B. New designations for genes and mutations - New genes or mutations will be designated by characteristic, locus, allele, and then the order of identification or mutational event. Three letters will be used to identify new characteristics. Consecutive numbers will be used to identify the order of identification or mutational event. Loci will be designated by numbers and alleles by letters when they are identified. For example, des--6 indicates that this is the sixth gene or mutation identified for the characteristic des (desynaptic). des 1-6 and des 2-7 indicates that gene or muational events 6 and 7 for the desynaptic characteristic have been shown to be at different loci and those loci are then designated 1 and 2, respectively.
des 1a6, and des 1b8, indicates that the gene or mutational events 6 and 8 for the characteristic desynaptic have been shown to be at different alleles at locus 1 and those alleles are then designated a and b.
4. Coordinators for chromosomes, gene (mutation) collections and chromosomal variations - Individuals were appointed as coordinators for chromosomes, gene (mutation) collections and chromosomal varia tions. It was agreed that the duties and responsibilities of the coordinators should be as described in BGN 2, p. 15.
5. Appointment of members to the committee - It was agreed that the organizing committee of the symposium should appoint the committee members. The present members are J. Jensen, U. Lundqvist, J. Moseman, R. Ramage, F. Scholz, A. Yasuda, T. Tsuchiya, Chairman, and D. von Wettstein.
