8 Investigating natural variation in barley to identify genes involved in adaptation Luke Ramsay
9 Variation within cultivated barley Genome wide association genetics Driven by development of SNP genotyping platform Brought different areas of research together Gene space sequence - step-change for barley genetics
10 Delineation of winter : spring division SNP discovery with RNA-Seq 9K iselect genotyping platform - Community uptake Detailed SNP genotyping cultivated barley germplasm Winter: Spring division 9K iselect - genetic linkage map Comparison genomic regions associated with difference
11 Genetic Divergence Genomic regions associated with Spring/Winter divergence H 2H 3H 4H 5H 6H 7H F ST is a measure of genetic differentiation. Peaks represent where one allele is present in the winter population and another allele is present in the spring population Jordi Comadran
12 Candidate gene discovery & verification 9K iselect - genetic linkage map synteny Candidate gene; barley homologue of Centroradialis Barley mutant collection - derived NILs genotyped Early heading Praematurum-c (mat-c) allelic series
13 Adaption to new environments - HvCEN 40 o C max 40 o C max o C min 20 o C min precip Scandinavia Fertile Crescent precip Fixation of haplotype III in European Spring barley Post domestication selection of existing allelic form shift in flowering time
14 Markers in backcrosses Backcross Inbred Lines (BILs) for mapping Backcross conversions Marker assisted breeding in Australia Fixation of target genes e.g. TILLING Advanced Backcross QTL Examples in many crops now Single Recombinant Chromosome Substitution Libraries (RCSLs) Work on barley in UK and USA
