Catalogue listing 11/08/99
NEW  Passport data on Catalouge entries

The lines listed in this catalogue are the designated source of alleles as published in the Pisum Genetics Association Pisum gene list. For many alleles, the line designated as the source line is the line in which the mutation was first isolated (initial line). Where the background of the original mutation is unsuitable as a parent due to low fertility or where the character is epistatic to other alleles at different loci, additional representative lines are listed that carry the alleles as published in the Pisum Genetics Association Pisum gene list. For many alleles the line designated as the source line is the line in which the mutation was first isolated (initial line). Where the background of the original mutation is unsuitable as a parent due to low fertility or where the character is epistatic to other alleles at different loci, additional repres alleles as published in the Pisum Genetics Association Pisum gene list. For many alleles the line designated as the source line is the line in which the mutation was first isolated (initial line). Where the background of the original mutation is unsuitable as a parent due to low fertility or where the character is epistatic to other alleles at different loci, additional representative lines are listed. Duplicate independent mutations are also recorded with the line number printed as superscript (<) as specified in the guidelines for registration of gene symbols (PNL 1977 9 67-70).

Alleles which are either semi-sterile or lethal in the homozygous state are denoted by the use of the symbol / prefixed to the gene symbol.

Linkage group assignments (chr) have been revised to be consistent with the current linkage map (Pisum Genetics 1996 28 pages 1- 4). This has been achived in all but a few cases where insufficient linkage data is available.

While attempts to revise the gene list are still in hand a number of inconsistancies do still appear in this list. It is hoped these will be resolved in the next edition of the catalogue which will also include lines for new alleles.

The lines are maintained at the John Innes Centre with saftey duplicates held at the Nordic Gene Bank acting as the base collection. The lines are obtainable free of charge on request subject to availability from the John Innes Centre.


The Catalogue

The listing is based on valid gene symbols as appear in the gene list. The listing is arranged by loci in alphabetic order. Loci are presented under their mutation type designations.


Valid symbol Over time changes in symbol use have occurred. This field gives the current valid symbol for the loci.


Status VAL=valid, SYN= synonym, PRO=provisional


Inheritance DOM= dominant REC= recessive SEM= semidominant/incomplete


Linkage group Linkage group to which the locus has been assigned as appear in the current linkage map.


Gene symbol Symbol under which the gene was first published. For the majority this is also the valid symbol. In instances where gene symbol has changed and is no longer valid are indicated by the status field indicating SYM.


Allele Symbol for the allele present. For some systems where two independent loci may act more than one symbol is given eg. fs, fas Pu, Pur er-1, er-2 .
/ indicates a lethal or semi-sterile mutation maintained as a heterozygote.


Line status Type or representative
Type is the line in which the mutation was first isolated or the parental line carrying the wild type allele. In many cases the initial line may be unsuitable for use for example due to fertility problems, weak background. Representative line indicate the presence of the allele in a background other than that of the original. These may represent better candidates for use in studying the caracher or as parents for crossing into other backgrounds.


JII No. Accession number as appears in the John Innes Pisum collection.
