Grant Description

Summary and Description of the grant

Reference Brassica mapping populations will be made available together with the associated key data sets (genetic linkage map, provenance and quality assurance validation). Seed will be provided by WHRI in the form of quality assured 'starter packs', and the future distribution and regeneration of the populations will be managed on a cost-recovery basis. DNA from founder lines of species-specific diversity sets will be made available for molecular allelic screening. Integrated consensus linkage maps for the Brassica A and C genomes with sequence tagged markers and reference 'conserved synteny block' nomenclature will be developed based on existing screening of SSR markers on parent lines. Mapping populations will be scored with polymorphic markers and the data used to generate reference maps based on consensus conserved synteny blocks in common with Arabidopsis. To underpin ongoing trait-led genetic and genomic projects QTL datasets will be collated and prioritised, and converted to a consensus format for comparative analysis. This will also assist in making direct connections between fundamental research and crop-related traits selected in breeding programmes. Exploitation of Brassica genome sequence through reverse genetic approaches requires access to TILLING and RNAi capability. Induced variation of multiple gene copies will involve a TILLING population in B. rapa genotype R-O-18, together with leadership of an international Brassica TILLING consortium and generation of a radiation mutant population. An RNAi pipeline for down regulation of multiple gene copies will be established initially in B. oleracea and B. napus, and a B. rapa transformation system developed for UK researchers. Validation of the reverse genetic technologies will focus on specific genes with well characterised phenotypic effects, and will allow comparison of the different approaches in polyploid brassicas. The project will underpin a range of existing and new trait-focused Brassica projects.
