Expression analysis of PR-1 gene in response to <i>V. albo atrum</i> infection.

<p>(A) cv. Celeia and (B) cv. Wye Target for infected (+) and control plants (−) at three different experimental time points (10, 20, 30 dpi). Expression values were normalized with three normalization factors: YLS8/DRH1 (two best reference genes), 14 best reference genes (resulting from NormFinder) and least stable gene (<i>NADH</i>) and are displayed as normalized and non-normalized (raw) values. Bars indicate standard errors.
