Fig. 1: Shared transcriptional responses to warming.
From: Increased microbial expression of organic nitrogen cycling genes in long-term warmed grassland soils
Shared protein family domains (Pfams) associated with organic N degradation that had higher mean relative transcript abundances under warming than ambient conditions (see Methods for details). Each heatmap is normalized by row (z score). Biological replicates are ordered by their temperature profile, and the potential target substrates of each Pfam are indicated by the colored circles after the family domain name. Significant differences between ambient and warmed conditions for each Pfam were assessed by parametric or nonparametric t-tests (two-tailed), depending on whether or not the variable met parametric assumptions. All p values were adjusted for the false-discovery rate (Benjamin-Hochberg correction). Adjusted significant p values < 0.05 are indicated on the left of each heatmap by *, and p values that became nonsignificant after correction are indicated by ¥. The results of the full statistical analysis and exact p-values are presented in Table S7.
