^aDerived from the MAS 5.0 report file

^bPresent in all six replications per genotype. There were 10,491 present calls in common among all three genotypes (18 hybridizations)

^cC.I. is the standard abbreviation for Cereal Introduction. Mla1, Mla6, and Mla13 are alleles conferring specific resistance to the powdery mildew fungus. Ten to 20 seedlings for each species were harvested and pooled for RNA preparation, labeling, and hybridization. Data were taken from six independent biological replications

^dAverage ± sd of all present calls in each replication based on six independent RNA isolations. Seedlings harvested directly after inoculation with powdery mildew

^eCalculated as a percentage of baseline barley leaf probe sets that exceed the probe pair threshold (present calls)
