Validation of microarray data by qRT-PCR.

<p>qRT-PCR log2 fold changes (−ΔΔCT) are shown for two markers A) <i>prCopia1</i> and B) <i>prCRN7</i>. PR_76099 was used as endogenous control gene and expression levels were standardized to the genome sequence strain Pr-102. For <i>prCopia1</i>, because the standard Pr-102 had the highest expression level, its expression was offset by 16 for presentation purpose.
