Sequencing the Tomato Genome A model Solanaceous species
Uses of the tomato genome sequence • Representative genome of Solanaceae, will be extremely useful in comparative genomics and data mining • Greatly facilitate map based cloning of important fruit quality genes in tomato • Tomato and potato carry a rich diversity of genes for biotic and abiotic stress tolerance • Underpin current research interests in Solanaceaous species in the UK • Tomato VIGS for functional genomics

Relevance to BBSRC Mission and Priority areas • In line with mission to support basic research which will impact on UK quality of life • Fully aligned with priorities for several BBSRC • committees including PMS, Agri-Food, GDB, EBS • e.g. Comparative Functional Genomics, Bioinformatics Genes to Food Products • Letters of support from Syngenta, Unilever, ATC, • BPC , TGA
The UK Sequencing initiative is part of an International Consortium International Steering Committee led by Dani Zamir and Marc Zabeau, UK contacts, Gerard Bishop and Graham Seymour USA UK Netherlands China Korea France Italy Spain
UK Contribution to Sequence the Gene - Rich Regions on Chromosome 4 • Why 4? • Contains important QTLs in Potato and Tomato relevant to UK user community (esp. SCRI) • Gene space on this chromosome can be sequenced at reasonable cost

QTL loci on tomato Ch4 include those for fruit texture and colour Texture, Texture, Colour Early Ripening
UK Contribution to Sequence the Gene - Rich Regions on Chromosome 4 • Aim to sequence chr4 ~25-30 Mb of gene- space
Release of Sequence • Immediate release into public domain • through EMBL/GenBank
Bioinformatics • International bioinformatics steering group established chaired by Lukas Mueller at Cornell • Training provided by Cornell • Ch4 sequence will be annotated in UK at • HRI / Imperial • Annotated Sequence release through • Solanaceae Genome Network (SGN) website • and database. Mirror site in UK.
Dissemination of information to UK community • Annotated Sequence released through • Solanaceae Genome Network (SGN) website • and database. Mirror site in UK • UK website will adapt to needs/requests of UK user community • UK site to contain useful listings including, current grants genetic and genomic resources, conferences etc… • UK Solanaceae Community meetings • to be organised. First meeting to be hosted at Unilever.
Key Milestones • Sequence of Chr12 and annotation • UK portal for UK users running • Finished Sequence of Chr 4 • Finished Annotation of Chr 4 • All data on UK and SGN web site
