Endogenous VvSWEET4 expression and glucose contents in hairy root lines after infection with P. irregulare. (A) VvSWEET4 expression was measured in control hairy root lines (A4 and pBin) 3 days after infection with P. irregulare. Transcript levels of VvSWEET4 were normalized to grapevine GAPDH and EF1α transcript levels. Relative expression indicates normalized expression levels in inoculated roots compared to normalized expression levels observed in mock-inoculated roots. Data represent means ± SD of three biological replicates. (B) Levels of soluble glucose were determined in hairy root lines 3 days after P. irregulare infection. Data represent means ± SD of 4 to 6 biological replicates. Means with different letters are significantly different at p ≤ 0.05 (Tukey Contrasts).
