The John Innes Pisum Collection

 The collection is broad based and comprises 3611 accessions including a wide range of wild and semi-cultivated material in addition to landraces and cultivars from many regions around the world. The collection also includes near-isogenic series for a number of genes as well as sets of host differentials for all major pea diseases. The collection incorporates the International collection of mutation stocks on behalf of the Pisum Genetics Association in collaboration with the Nordic Gene Bank which serves as the base collection and backup for the work at the JIC. A web searchable catalogue (PGene) of genetic stocks for Pisum is maintained and can be accessed via the Database navigation button. A number of recombinant inbred populations used for the mapping programmes at the JIC are also maintained as part of the collection.

We gratefully acknowledge financial support for the maintenance of the pea collection from Defra.

The John Innes Pisum Collection works closely with other organisations and has had a number of successful collaborations that have resulted in the development of important data sets that add value to the collection and enhance its utility. Over the coming year we will be working to enhance the available data that have arisen from these outputs as we move towards flagging and developing ‘community Resources’.
The first is an output of a long standing collaboration between Noel Ellis of the JIC and Andy Flavell based at the University of Edinburgh to explore and develop molecular markers to gain an understanding of the genetic diversity within Pisum and its origins and to apply them to genotype complete collections. This was achieved over a long time period and several funding grants. The culmination of the work came with the following paper;
Jing R, Vershinin A, Grzebyta J, Shaw P, Smýkal P, Marshall D, Ambrose MJ , Ellis THN, Flavell AJ (2010) The genetic diversity and evolution of field pea (Pisum) studied by high throughput retrotransposon based insertion polymorphism (RBIP) marker analysis. BMC Evolutionary Biology 10:44doi:10.1186/1471-2148-10-44
Original data sources, microarray and map data can all be found on the JI Pisum Collection Germinate Database and this resource is cross-referenced to accession entries within 'SeedStor'.
This work has provided a new baseline description for the collection which is the basis of further study as we look to target particular sections of the diversity for particular traits of interest.

Links to output to further collaborations and resources will be provided over the coming months.
