2. Genetic Maps & Markers Study: population & set of markers Map: single linkage group (nuclear or plastid) Comparative map: (within or between species) –Marker_ID –Sequence Markers: –morphological, isozyme, DNA (cDNA, TE’s, random genomic) Other features: –centromeres, QTL (presented as intervals)

3. Phenotypes Mutant Instance of a gene = allele Detected by assaying a particular allele in a particular genetic background (germplasm) in a particular environment (location, condition, time) and comparing it to a reference (wt)

4. Gramene’s approach to mutant curation –Provide capability of mining down from description of a phenotype to map locus to gene to allele –Provide multiple entry points for associating genotype and phenotype: phenotype (trait), genotype, environment, locus (map position), biochemical pathway, gene (sequence), protein

5. Phenotypic Assay Observable/measurable difference due to: –one or more mutations (alleles) –at specific loci (genes) –that interact with the rest of the genetic background (germplasm) –under a given abiotic environmental regime defined by temperature, light, moisture, nutrition, space –and biotic regime, i.e., exposed to specific microbes, insects, plants –measured in a given location, time (season, year) –and stage of development.

7. Right: normal-type (Sasanishiki, a japonica cultivar). Left: semidwarf-type (isogenic line of Sasanishiki with sd- 1). Image from Monna-2002 (DNA Research 9: 11-17). Phenotypic comparison of sd1 and wild type Sd1, semidwarf-1 (dee-geo-woo-gen dwarf, d47) Semidwarfness of an isogenic line (sd1) in the ‘Shiokari’ background. The mutant image was kindly provided by Dr. Kinoshita.

15. Quantitative Trait Loci (QTL) Population x Marker set x Phenotypic assay x Statistical test of association Generally many phenotypes assayed for each population and multiple loci identified per phenotype Entry into DB different than with mutants but information intersects with mutants phenotypic assay, gene, allele Entry is always via linkage to set of markers

16. RiceGenes QTL display QTL Homoeologous regions TIGR BAC Consensus map

17. Limitations Genetic position poorly comparable bt/n studies, map types (genetic/physical), species –Misleading sense of accuracy Consensus (integrated) map difficult to update and keep consistent –Replaced with sequence-based I-Map which will continue to develop as the FPC contigs are extended

18. Queries of interest related to QTL What mutants have been mapped to the region containing QTL ”a"? What ORF's are associated with the region containing QTL “a”? What are the GO/TO terms associated with candidate ORFs in interval ”a"? Given interval ”a" in rice, identify homeologous regions of other grasses and show the array of mutants/QTLs associated with similar phenotypes (same TO ID’s) that map to each region on the comparative maps.

19. Queries, con’t. Which genotypes (i.e. rice strains) are associated with an increase in trait ”b” due to a QTL locus ”a"? Cloned gene ”c” is associated with trait "a”. Is it a member of a gene family? If so, what is the association of family members with specific biochemical pathways, phenotypes, or conditions? Cloned gene “c” codes for protein “x”, which is part of pathway “y”. What other proteins and pathways are associated with trait “a”? Do any of the genes coding for these proteins map to the region containing QTL locus “a”?
