The list notes the main phenotypic characters and gives references to their descriptions. Synonyms are listed in parentheses after the priority gene-designation. When a symbol does not follow the revised nomenclatorial rules or has not become well established in the literature, it also is given in parentheses and it is hoped that in future publications these symbols will be changed. One or more seed sources for each gene is given whenever possible. The authors of the original publications may be able to supply seed stocks of the other genes. Anyone who can supply stocks of such genes is requested to tell C. M. Rick about them to aid in completing this list.
A number of new genes have been described only in TGC Reports. These are cited in this list by report and page number. Thus TGC 3:5" means that a description of the gene will be found on page 5 of the 3rd report. Most authors will likely publish descriptions of these genes at a later date in standard publications.
