From: A core root bacteria contribute to plant growth and anisodine accumulation of Anisodus tanguticus
Core root bacterial functions annotated according to FAPROTAX. (a) Spearman correlation analysis of functional group and aboveground biomass, nitrogen content and root tropane alkaloids content of Anisodus tanguticus. The numbers in the graph indicate the R-value. The colors in the graph indicate the P-value. The red and blue indicate positive and negative correlations, and the color depth indicates strong correlation (* P < 0.05, ** P < 0.01, *** P < 0.01). (b) The relative abundance of the different functional groups
