Additional file 2 of A successful defence strategy in grapevine cultivar ‘Tocai friulano’ provides compartmentation of grapevine Flavescence dorée phytoplasma

Additional file 2: log2 relative transcript level of selected categories of genes obtained from 1-year-old canes grown on symptomatic (S, AS and AA) and asymptomatic (A) 2-year-old arms of Flavescence dorée infected 'Tocai friulano' plants or from healthy plants (H). For each gene the relative expression was calculated by setting a value of 1 as the lowest value among S, AS, AA, A or H samples. Samples were collected for two years (2020 and 2021) during September and November. Normalisation of transcriptional levels were performed using GAPDH and COX as endogenous controls. Significant differences (P ≤ 0.05) among treatments are indicated by different letters, according to parametric one-way ANOVA using Student Newman Keuls test.
