Iridoids dynamic is positively associated with temperature in S. ningpoensis. (A) Potential cultivated region predicted for S. ningpoensis according the GMPGIS. (B) The sampling points of S. ningpoensis in China are shown in the left panel. The red dots represent the sampling points. Pairwise comparisons of the ambient-level distribution of typical metabolites in S. ningpoensis are shown in the right panel, with a color level that refers to Pearson's correlation coefficients. Environmental factors (temperature, precipitation, relative humidity, and hours of sunning) are correlated with the content of metabolites (angroside, harpagoside, acteoside, cinnamic acid) with the Mantel test. The width of the edge reflects Mantel's r statistic for the distance correlations, while the color indicates the level of statistical significance. (C) Growth status of S. ningpoensis under different temperatures (control: 28°C; warm: 35°C; heat: 42°C). (D) The contents of five components in dry leaves and roots under different temperatures. The average ± SD values from three biological repeats are shown. Statistical significance was determined using t-test; ***P < 0.001, **P < 0.01, *P < 0.05.
