Nomenclature: Brief sections on nomenclature and symbols have appeared in: Neurospora Newsletter 8:23 (Barratt and Perkins, 1965); Neurospora Newsletter 14:13 (Barratt, 1969); Neurospora Newsletter 20:38 (Perkins and Barratt, 1973) and Adv. Genetics (Perkins and Barry, 1977). In the Newsletters, FGSC has made this appeal: "Please do not use the FGSC number as a substitute for the genotype, allele or locus."
With this issue of the FGSC catalog we have tried to use correct nomenclature. If you find errors please notify the FGSC.
Part IX. Key to Symbols
The number usually refers to an isolation number. Numbers without prefixes indicate the original Beadle and Tatum mutants. The few exceptions are indicated by underlining the allele numbers.
Prefixes used are as follows:

Seale to designate reversion by nitrous acid. WRR Used by G.A. Marzluf WRU Used by T.W. Seale to designate reversion by ultraviolet Y Yale- used by E.L. Tatum(1945- 49); X Used by B.M. Eberhart, also N.H. Giles (to 1973) Z H. Zalkin Suffixes used are as follows: Ab aberration (r) resistant (d) dependent (s) sensitive (p) pH- sensitive (t) temperature- sensitive pr partial reversion T translocation (reciprocal or insertional)
In addition, in cases where more than one gene mutation has been recovered from a stock, a suffix is added to the isolation number to differentiate the two; i.e., Y30539y is an allele of ylo-1; y30539r an allele of rib-2.
The symbols are designed to provide the general nature of the background of each stock. No attempt is made to provide detailed information. Several nonidentical lines of Emerson, Lindegren and St. Lawrence wild types are in use. As stocks improved, a given laboratory often changed to different but related wild types. Where detailed information is essential, the investigator should write directly to the Stock Center. For origin of some of the wild type strains, see Barratt, R.W., "Origin of Important Wild Type Stocks of N. crassa", Neurospora Newsletter 2:24- 25 and Neurospora Newsletter 3:19; Case, M.E. et al. "Further Information on the Origin of the Yale and Oak Ridge Wild Type Strains of N. crassa", Neurospora Newsletter 8:25-26, Catcheside, D.G. 1975 "Occurrence in Wild Strains of Neurospora crassa of Genes Controlling Genetic Recombination", Aust. J. Biol. Sci. 28:213-225 and Newmeyer, D. et al. 1987 "An annotated pedigree of Neurospora crassa laboratory wild types, showing the probable origin of the nucleolus satellite and showing that certain stocks are not authentic", Fungal Genetics Newsletter 34:46-51.
For many of the original mutant strains of Beadle and Tatum, only incomplete records are available as to whether existing strains are original or derived. Where any doubt occurs, the symbol O? is employed to indicate uncertainty.
Symbols used are as follows:
A Abbott C Chilton E Emerson L Lindegren M Mixed RL Rockefeller-Lindegren SL St. Lawrence AxC Abbott crossed with Chilton AxL Abbott crossed with Lindegren AxM Abbott crossed with mixed LxE Lindegren crossed with Emerson
Numbers after symbols (as SL4) refer to the number of backcrosses to the indicated background. SL4 should be read "back- crossed into St. Lawrence background four times."
A/a mating type alleles d lethal producing deliquescent asci; wild type allele D (formerly called 1,L) E lethal preventing ascospore maturation on certain media, producing 8- spored asci on other media (dominant); (wild type allele e) I lethal producing indurated asci (dominant); wild type allele i dwarf or yellow dwarf; wild type allele v
A mating type alleles S sitophila C crassa T tetrasperma E England V Virginia, USA
Symbols used to indicate the mutagen employed are as follows:
A acridine ICR-170 MDAB methyl-dimethylaminobenzene AFT-B Alfatoxin B1 MMS methyl methane sulfonate 2-AP 2-Aminopurine N neutrons BUDR 5-bromodeoxyuridine NA nitrous acid Co-60 cobalt 60 NG N-methyl-N'-nitrosoguanidine DEB diepoxybutane 4-NQO 4-nitroquinoline 1-oxide DEO diepoxyoctane O no mutagen, allele present in parent strain DS diethyl or dimethyl sulfate P beta propiolactone EMS ethyl methane sulfonate RIP Repeat Induced Point mutation FUDR 5-fluorodeoxyuridine TR transformation G gamma radiation S spontaneous HA hydroxylamine S35 sulfur 35 M mustard (nitrogen or sulfur) UV ultraviolet light MC methylcholanthrene X x-rays UV+M ultraviolet + mustard simultaneously
