Fig 1.
Heat-map and clustering of biochemical changes after the inoculation of different strains of fungal endophytes, in both leaves and berries of grapevines.
Heat-map were drawn according to the response indexes (RI) values (S3 Table), and each row represents a biochemical variable and each column represents a fungal strain treatment. RI values were centered and scaled in the row direction to form virtual colors as presented in the color key. Biochemical parameters that showed a similar response to the inoculations of fungal endophytes were clustered together.
Fig 2.
Boxplot of physio-chemical traits in response to fungal endophytes inoculations.
Green colored boxes represent the leaf physio-chemical response ranges, and purple colored boxes represent the berry response ranges.
Fig 3.
Boxplot of the impacts of inoculated fungal strains on grapevine physio-chemical traits.
Green colored boxes represent the impacts on leaf biochemistries, and purple colored boxes represent the impacts on berry biochemistries.
Fig 4.
Principal component analysis (PCA) of the impacts of endophytic fungal inoculation on leaves and berries of grapevines.
A and C are discriminations of leaves (green) and berries (red) after inoculated with different fungal strains. B is loading plot of biochemical parameters for the first two principle components, PC1 and PC2. D is loading plot of biochemical parameters for the second and third principle components, PC2 and PC3.
