2D density plots illustrating the relationships between the relative abundance of the two most abundant bacterial species of the potential pathobiota and the total relative abundance of the microbiota OTUs identified by sparse partial least-square regression (sPLSR). a Example with X. campestris in the seasonal group “spring without autumn” in the leaf compartment (Pearson’s r = −0.15, P = 0.0187, n = 262 samples). b Example with P. viridiflava in the seasonal group “spring without autumn” in the root compartment (Pearson’s r = −0.17, P = 0.0006, n = 258 samples). Red-to-blue color gradient represents high-to-low density gradient
