Fig. 7From: Important ecophysiological roles of non-dominant Actinobacteria in plant residue decomposition, especially in less fertile soilsBoxplots showing the average relative abundance of Actinobacteria and related gene classes associated with different ecological traits in Actinobacteria metagenome under different soil fertilities. The relative abundances were log-transformed. GH glycoside hydrolase, GT glycosyl transferase, PL polysaccharide lyase, CE carbohydrate esterase, CBM carbohydrate-binding module, AA auxiliary activities. “*” denotes significantly different at P < 0.05, “**” denotes significantly different at P < 0.01, “n.s.” denotes P > 0.05Back to article page
