Relationships between (a) microbiota β-diversity and (b) potential pathobiota β-diversity based on a sparse partial least-square regression (sPLSR). Only OTUs with a loading value above 0.2 in more than 75% of the 1000 Jackknife resampled matrices were considered as significant. The color gradient indicates the strength of the loading values for both microbiota OTUs and potential pathobiota OTUs (yellow: 0.2 < loadings < 0.35; orange: 0.35 < loadings < 0.5; red: loadings > 0.5). “All,” “Aut,” “Sw/ A,” and “Sw/o A” stand for all samples and samples from the three seasonal groups (i.e., “autumn” populations, “spring w/ autumn” populations, and “spring w/o autumn” populations), “L” and “R” stand for leaf and root, respectively. “All” n = 1655; “Aut—L” n = 314, “S w/ A—L” n = 245, “S w/o A—L” n = 262; “Aut—R” n = 309, “S w/ A—R” n = 267, and “S w/o A—R” n = 258
