Fig. 7: Contribution of microbial (bacterial and fungal) phyla to microbial CAZymes genes for SOM decomposition following different periods of extreme drought.

A–E indicate the microbial community involved in the starch, cellulose, hemicellulose, pectin and lignin decomposition, which were organic matters derived from plants. F, G indicate the microbial community involved in the chitinase and glucan decomposition, which were organic matters derived from fungus. H indicate the microbial community mainly involved in the peptidoglycan decomposition that derived from bacteria.
