Microbial transcriptome patterns highlight increased pedogenesis-related activity in arid soils under simulated humid conditions.

ABSTRACT:

Background

In arid and semiarid environments, microbial activity is restricted by low water availability and high evapotranspiration rates, and soil development is limited. Under humid conditions, such limitations can be overcome, accelerating pedogenesis by microbial processes. Our study aims to broaden our understanding of soil development under a climate change scenario toward humid conditions and to identify the microorganisms that help transform initial soils from arid and semiarid sites. We characterized pedogenetic microbial processes and how their gene expression differs between soils from arid and semiarid sites under a sixteen-week climate simulation experiment using metagenomic and metatranscriptomic approaches.

Results

We found that an intense functional response
