Embryo-derived tissues at four days after imbibition (150 lines) and seedling leaves at 12 days after imbibition (subset of 34 lines) and three biological replicates of each parental cultivar (Steptoe and Morex) for each tissue were used for the isolation of total RNA and hybridization to the Barley1 22K GeneChip. + +<P>ARNIS: Please revise and update this text.

Many agronomic quality traits have been mapped using this population (for the lists see BeerGenes web-site http://gnome.agrenv.mcgill.ca/bg/). + +<P>The sample used in this study consists of 150 Steptoe x Morex doubled haploid recombinant lines (Kleinhofs et al. 1993) was used to obtain embryo-derived tissue. For the seedling leaf tissue a subset of 35 lines was used. This subset was selected based on evenly spaced crossovers along each of seven barley chromosomes.

Each cabinet accomodated 40 (13x13 cm) pots. Humidity was set to 70%, with light conditions for 16 hours light at 17C and 8 hours dark at 12C. The cycle started at 10 am with lights on. Light intensity was 337-377 mmol m-2 s-1, measured at the beginning of the experiment, 11 cm from the light source. Measurement was done using Sky Quantium light sensor at 15oC. Plants were placed 55 cm from the light source (from the bulb to the surface of the vermiculite). Ten sterilized seeds per pot were planted and 3 pots per genotype / per cabinet were used. After 12 days, leaf blade and sheath from 5-7 the same size plants was cut off, bulked and flash frozen in the liquid nitrogen. + +<P>To obtain embryo-derived tissue, growth room#2, AN building, SCRI, with the standard laboratory bench positioned in the middle of the room was used to germinate sterilized seeds. Seeds were placed between three layers of wet 3MM filter paper in the 156 10 mm Petri plates. Thirty to fifty seeds per line (per Petri plate) were used. Germination was in the dark, 16 hours at 17 deg C and 8 hours at 12 deg C. After 96 hours, embryo-derived tissue (mesocotyl, coleoptile, and seminal roots) from three grains was dissected and flash frozen in the liquid nitrogen. Germination and collection was repeated two more times. Complete randomization of the Petri plates was done for each germination event. Tissues from all three germinations (collections) were bulked before RNA isolation. Three replicates of the parental cultivars were germinated for each collection. + +</Blockquote> + +<Blockquote> +<P><B>RNA Sample Processing:</B> +<P>Detailed descriptions of these procedures can be found under the ArrayExpress (http://www.ebi.ac.uk/aerep/?) protocol P-MEXP-4631 (Caldo et al. 2004). + +<P><B>Replication and Sample Balance:</B> + +<P><B>Experimental Design and Batch Structure:</B> + +</Blockquote> + + + +<P class="subtitle"> Downloading all data:</P> +<Blockquote> +<P> The following are ArrayExpress (http://www.ebi.ac.uk/aerep/?) experiment IDs: +E-TABM-111 (leaf, 41 chips) and E-TABM-112 (embryo derived, 156 chips).
