Macrogenomics reveal the effects of inter-cropping perilla on kiwifruit: impact on inter-root soil microbiota and gene expression of carbon, nitrogen, and phosphorus cycles in kiwifruit.

3.7 Correlation analysis of soil carbon, nitrogen, and phosphorus cycling functional genes with environmental factors and functional microorganisms Heat map analysis of soil carbon, nitrogen and phosphorus cycling genes correlated with soil physicochemical properties and enzyme activities ( Figure 9 ), korA/B , which is associated with carbon fixation, was positively correlated with S-β-GC, and TC and SOM had high concordance, and negatively correlated with most of the carbon cycling genes ( Figure 9A ); GDH2 , norB were highly significant negatively correlated with TC, SOM, AN and S-LAP, glnA, nirB and gltB were all significantly negatively correlated with SOM, where gltB and AN were highly significantly negatively correlated, and nirA was the opposite, but TN showed a weak correlation with the nitrogen cycle; for the soil phosphoru
