Fig. 6

Relative abundance differences of grapevine trunk disease (GTD)-associated fungi at the species (A) and genus (B) levels between comparable groups are indicated in the upper right side of the figure. Grey indicates no significant difference in the relative abundance of a certain species or genus between the groups being compared, while green and yellow indicate significant differences. Green indicates that the relative abundance of the former group is significantly higher than that of the latter one, while yellow indicates the opposite. For example, when AsPE.19 (the rhizoplane and endophyte fungi for samples collected from asymptomatic grapevines in 2019) was compared with AsPE.20 (the rhizoplane and endophyte fungi for samples collected from asymptomatic grapevines in 2020) (AsPE.19 vs. AsPE.20), the relative abundance of Dactylonectria torresensis in the former group was significantly lower than that in the latter group (indicated in yellow). The relative abundance of Cadophora luteo-olivacea was significantly higher in the former group than in the latter one (indicated in green). Statistical differences are indicated by q-values < 0.05 based on Wilcoxon tests
