Summary

• What do we need (covered in previous talks)• What do we have (quick re-cap)• DArT markers: what and why ?

• New applications• Put in context of yesterday morning• Next steps - and the future

– (Jellen, Jackson, Rines et al)

Marker types – advantages & use in oats

Restriction + Hybridization: RFLP

Random amplification: RAPD

Restriction + amplification: AFLP

Amplification of repeats: SSR

Repeat-based amplification: IRAP, ISSR, REMAP, IMP

Amplification + hybridization: DArT

Targeted amplification: SRAP, SCAR

Targeted – many methods: SNPOther Protein,

Inventory of oat QTLs

• Based on survey of literature (Wight):– 710 reported QTL in oat– From 49 different oat populations– 43 different traits – 81 ‘trait methods’

• http:// avena.agr.gc.ca/oatgenes

• Too much of a good thing?

• Some assembly required!

Many markers, many maps, many QTLs

Where’s the problem?

What is missing from the oat toolbox ?

• An economical, efficient, and accurate method to – merge information from different maps – generate a ‘master’ consensus map

• Quickly address new information in new germplasm– new crosses, association mapping– breeding applications

• Universal anchor markers – that anyone can use – available as a service– Locus-specific, retain identity – Can be put on future sequence framework

• SSR? SNP? Yes! – but we couldn’t wait• Not a Band-Aid solution

DART – Marker Discovery

Pooled Genomic DNA- From 100 global varieties- Reduced complexity- Random clones

- 3 discovery arrays-6500 spots per array- (20K potential markers)

Genomic SamplesFrom 200 global varieties+ 80 KxO mapping lines

Label, hybridize, wash, and scan

Page 11: Community progress toward an integrated toolbox and consensus map for oat Nick Tinker, Eric Jackson, Eric Jellen, Howard Rines, et al

• Differential spot (usually from differential restriction or amplification in complexity reduction step)

• Score these on discovery panel + mapping lines• Make second-generation typing array• Optional: sequence clones

Cost and availability of DArT

• Available to ‘non-consortium’ as soon as paper is accepted (fall 2008 ?)

• Paper will contain detailed resources• Add information to Graingenes • All sequence will be submitted

• DiversityArrays.com• Current cost of 2700-clone genotyping array:

– $AUD 5500 (approx. 5K) – 94 genotypes

Page 23: Community progress toward an integrated toolbox and consensus map for oat Nick Tinker, Eric Jackson, Eric Jellen, Howard Rines, et al

The way forward

• Snapshots of new initiatives and opportunities – Not all DArTS

• Integrative mapping and chromosome assignment (Segue to Rick Jellen)

Page 24: Community progress toward an integrated toolbox and consensus map for oat Nick Tinker, Eric Jackson, Eric Jellen, Howard Rines, et al

At AAFC

• DArTs will be cornerstone of AAFC ‘team project’ on association mapping– Panel of 350 lines of global origin– Everyone look for your favourite trait– Overlaps (complements) other panels:

• Jean Luc• ERA proposal

• DArTs will integrate targeted projects…….

Other current initiatives (posters etc)

• New maps and new traits…. • Various projects in evolution and diversity• Rossnagel et al – DArT breeder friendly• Olof Olsson – Tilling + ESTs *10K available now• Jackson, Anderson et al: improve SSR toolbox

– Then on to SNPs – Both SSRs and SNPs to incorporate DArTs

Page 28: Community progress toward an integrated toolbox and consensus map for oat Nick Tinker, Eric Jackson, Eric Jellen, Howard Rines, et al

Two key puzzle pieces (segue to Rick… )

• Ogle x TAM O-301 (136 RILs) – any day now– Expect 1000 mapped markers– 700 common to KxO– Eric Jackson – expanding population by 200 RILs – Plus other maps– Consensus mapping will still be a challenge

• Physical chromosome assignment– Need to expand work by Fox et al.– New strategies ….
