Analysis of the mRNA expression of the barley transgenes in the single (CPI6-plants, lines 5.4 and 9.8; CMe-plants, lines 3.4 and 8.9) and double (CPI6-CMe-plants, lines 6.4 and 8.2) T2 transgenic plants and non transformed control (Col), by real time quantitative PCR.

<p>A. Expression of barley <i>Icy6</i> gene. B. Expression of barley <i>Itr1</i> gene. Values expressed as the relative mRNA contents of the protease inhibitor genes were normalized to the Arabidopsis ubiquitin gene expression.
