The asynchronous co-induction of the alternative NAD(P)H dehydrogenase gene VvaND1 and the alternative oxidase (AOX) gene VvAOX23 in both tissues at 24 hpi in stems and at 2 wpi in leaves suggests that the two organs undergo oxidative stress at different time points after infection (Vanlerberghe, 2013). This evidence concerns the gene ACOX1 and infection.
