ABA metabolism and signalling pathways are sensitive to GLRaV infection. (a) Boxplots showing the abundance of abscisic acid (ABA), ABA glucose ester (ABA‐GE), and xanthoxin in 2017 and 2018 at prevéraison. Groups with nonoverlapping letters are significantly different (Tukey HSD, p < .05). (b) The effect of GLRaV infection(s) and rootstock on ABA biosynthesis and signalling genes. *Differentially expressed in 1 year; **differentially expressed in both years. One or two letters “r” indicate that the effect of a particular GLRaV infection differs between rootstocks at the same developmental stage in 1 or 2 years. Any notation requires the direction (up/downregulation) of the effect to be consistent in both years, even if a significant change occurred in only 1 year
