Figure 2

The difference in rhizosphere microbial function in different potato varieties under high nitrogen conditions. (A) KEGG N metabolism pathway analysis. The rectangular box represents the enzyme or component in the pathway, and a darker color indicates a higher relative abundance. (B) Comparison of relative abundance of enzymes or components in the nitrogen metabolic pathways of DN310 and DXY under high nitrogen conditions. (C) Bacterial secretion system metabolic pathways in KEGG database. Rectangular boxes represent the components of each secretory system. (D) Comparison of relative abundances of components of bacterial secretion system of DN310 and DXY under high nitrogen conditions. (B,D) Welch’s test was used to evaluate the difference; * p < 0.05, ** p < 0.01 and *** p < 0.001.
