Comparison of the relative abundance of the most abundant taxa of fungi in two grafting rootstock types. a The 10 most abundant fungal orders in standard rootstocks (H) and dwarfing rootstocks (L) samples based on ITS amplicon sequencing. b Fungal LDA value distribution histogram and (c) evolutionary clad. Abbreviations: H, L: standard rootstocks, dwarfing rootstocks. Notes: The LDA value distribution histogram shows the species with LDA score that is greater than the set value (the default setting is 4), that is the biomarker with statistical differences between groups. The species with significant differences in abundance across different groups and the length of the histogram represents the impact of different species (i.e. LDA score). In the clade map, the circles radiating from the inside to the outside represent the classification level from the phylum to the genus (or species). Each small circle for a different classification level represents a classification at that level, and the diameter of the small circle is proportional to the relative abundance. Species with no significant differences are uniformly colored yellow, and the different species biomarker follows the group to color. The yellow node represents the microbial group that plays an important role in the yellow group, and the green node represents the microbial group that plays an important role in the green group Significantly different species of bacteria with different grafting rootstocks at species level
