Fig. 2: Impact of litter quality and long-term drought on microbial physiology.
From: Drought and plant litter chemistry alter microbial gene expression and metabolite production
a Mean relative abundance of transcripts at level 1 of Subsystems classification in grass and shrub litter communities under ambient precipitation (n = 9–12). b Total number of genes annotated within each level 1 category (c) Frequency of significant transcript indicators (p < 0.05) in level 1 functional categories across litter type under ambient precipitation (n = 9–12). d Drought impact demonstrated as fold change in gene expression (at level 1) in communities from reduced precipitation relative to ambient. Asterisks mark significant drought-induced shifts in functional groups as analysed by one-way ANOVA (***p < 0.001; **p < 0.01; *p < 0.05; n = 9–12). e, f Frequency of significant transcript indicators (p < 0.05) in level 1 functional categories across precipitation treatments in (e) grass and (f) shrub communities (n = 9–12).
