Genetics of gene expression in barley

Material: Steptoe x Morex doubled haploid (DH) recombinant inbred lines

Tool: 22,801 unigene Affymetrix Barley Chip

Genetical Genomics Approach:

• Expression Data Analysis across parental lines and DH progeny

• eQTL analysis (identification of cis- and trans-acting regulators)

• Exploring the relationship between eQTL and mapped phenotypic traits

Steptoe Golden PromiseMorex

Seedlings 12 days after plantingThe length of the seedling leaves of any of the segregating lines was not significantly different

at this developmental stage (data not shown)

9 seeds per pot were planted in the vermiculate• all the seedlings from each pot were counted, measured and pooled for the RNA isolation

12 days after the planting

To perform genetical genomics approach we need:

• Segregation population (DH lines, RILs, F2...)

• Set of molecular markers polymorphic between parental lines

• Information about alleles of the markers in each of progeny lines (progeny lines genotypes)

• Genetic map as a linear arrangement of the markers from recombination values

• RNA profiling data for each of progeny lines

The SFP genetic map of barley

Page 26: Genetics of gene expression in barley Material: Steptoe x Morex doubled haploid (DH) recombinant inbred lines Tool: 22,801 unigene Affymetrix Barley Chip

Summary

We suggest a simple algorithm to detect SFPs from RNA profiling data of any segregation population combining homozygote progeny lines

Number of detected SFP markers is sufficient to create a high densitygenetic map for any unknown cross

Construction of genetic map, measurement of gene expression and mapping of eQTL can be achieved within the same experiment
