Fig. 6: Path analysis examining the effects of plant functional types, dominant mycorrhizal types of root symbiosis, background climate condition, and warming treatment on the response of root:shoot ratio.

From: Global systematic review with meta-analysis shows that warming effects on terrestrial plant biomass allocation are influenced by precipitation and mycorrhizal association

PFTS plant functional types (i.e., herbs or woody plants), MFTS dominant mycorrhizal fungi types of root symbiosis (i.e., AMF arbuscular mycorrhizal fungi, EMF ectomycorrhizal fungi, or AM-EMF mixed AMF and EMF), MAT mean annual precipitation, MAP mean annual precipitation, RR(R/S) response of root:shoot ratio. The solid and dashed lines indicate the significant (p-value < 0.05) and non-significant effects (p-value > 0.05), respectively, whereas the red and blue solid arrows indicate positive and negative effects (p-value < 0.05), respectively. We assigned ‘0’ and ‘1’ for herbs and woody plants, and assigned ‘0’, ‘0.5’, ‘1’ for AMF, AM-EMF, and EMF, respectively, in this analysis (Supplementary Data 2). Symbols *, **, *** indicate statistical significance with p-value < 0.05, <0.01, and <0.001, respectively, based on two-tailed tests. In Chi-square test for the path model, the P-value was calculated from one-tailed test.
