Availability of Stocks

Most stocks are maintained both as desiccated spores on silica gel and as freeze-dried spores. Strains that do not sporulate are stored at -80 and in liquid nitrogen. When a strain is requested, we start it growing here at the FGSC. Most strains can be shipped within a week. Some require more effort to revive and can take longer. Please consult us if there are any concerns about delays.

Deposit of Stocks

We solicit deposit of strains on which genetic or biochemical information is published or in press. We invite suggestions of valuable stocks which should be included. A deposit sheet is included at the end of the catalog or can be downloaded from the FGSC web site. Additions or corrections to linkage data, genetic background, references, etc. are welcomed. Additional information of many stocks can be provided upon specific request.

Shipment of Strains

Most strains are stored on anhydrous silica gel.
In preparation for shipment, a few crystals of the stock culture are transferred to fresh agar slants, and when growth can be seen, the slants are sent via UPS or international air-mail. In most cases, strains can be dispatched 2-3 days after receiving a request. Strains may be sent via FedEx if an additional fee is paid. Phone orders may be placed at 913-588-7044; the FAX number is 913-588-7295; We encourage the use of E-mail as this assures timely and accurate ordering. Orders may also be placed directly from the FGSC web site.


Thanks are due to the many investigators who have deposited stocks, as indicated by initials in the list. These and others have provided a valuable service by providing accessory information, correcting errors, and depositing improved strains to supplement or replace those originally listed.

Genetic Background

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."

d       lethal producing deliquescent asci; wild type allele D (formerly called 1,L)
