1 Sequencing the Tomato Genome A model Solanaceous species

2 Uses of the tomato genome sequence 1)Representative genome of Solanaceae, will be extremely useful in comparative genomics and data mining 2)Greatly facilitate map based cloning of important fruit quality genes in tomato 3)Tomato and potato carry a rich diversity of genes for biotic and abiotic stress tolerance 4)Underpin current research interests in Solanaceaous species in the UK 5)Tomato VIGS for functional genomics

5 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

6 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 USAUK NetherlandsChina KoreaFrance ItalySpain

7 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

8 QTL loci on potato Ch 4 include those for late blight and potato cyst nematode PACMAAC_ DPAGMAGT_ DPACMAGG_ PATMCAT_ DPCGMCAA_ STM PCAMAAC_ DPGAMCAG_155.0 PATMAGG_ DPACMATA_ EAACMCTG_ EACAMCAC_160.5 PACMACT_ DPGAMCAC_ EAACMCCA_ EACAMCAC_153.0 S PCTMCAC_ PGAMATC_ PATMAGG_ PACMATG_ PCTMCAC_ PATMACG_ PACMAAG_309.3 PCCMACG_ PAGMACG_ PACMAAC_185.0 PCCMATA_ PATMACG_295.0 PCCMATA_ ab1 IV PCN resistance AFLP markers cloned & sequenced Markers screened against potato BAC libraries –AFLPs –SSRs –RGCs ~70 BACs identified to date BAC fingerprinting in early 2004 EU APOPHYS project –Global potato physical map Target region Glenn Bryan and Robbie Waugh, SCRI

9 Texture, Colour Early Ripening Texture, QTL loci on tomato Ch4 include those for fruit texture and colour

10 Sequencing Strategy

12 UK Contribution to Sequence the Gene - Rich Regions on Chromosome 4 Aim to sequence chr4 ~25-30 Mb of gene- space

13 Release of Sequence Immediate release into public domain through EMBL/GenBank

14 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.

15 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.

16 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
