  1. aExpression validation was assessed as "Present/absent" when amplicons were only detected in either DpDf or wild-type. Semi-quanitative indicates that expression was detected in both DpDf and wildtype with semi-quantitative variation in agreement with the microarray results.
  2. bChromosome positions determined from oat × maize chromosome addition lines (Kynast et al., 2001).
  3. cNot tested due to failed amplification
