Shotgun metagenomics of deep forest soil layers show evidence of altered microbial genetic potential for biogeochemical cycling

Frey, Beat; Varliero, Gilda; Qi, Weihong; Stierli, Beat; Walthert, Lorenz; Brunner, Ivano (Frontiers Media S.A., 2022-03-01)

Soil microorganisms such as Bacteria and Archaea play important roles in the biogeochemical cycling of soil nutrients, because they act as decomposers or are mutualistic or antagonistic symbionts, thereby influencing ...
Shotgun metagenomics reveals distinct functional diversity and metabolic capabilities between 12 000-year- old permafrost and active layers on Muot da Barba Peider (Swiss Alps)

Perez-Mon, Carla; Qi, Weihong; Vikram, Surendra; Frossard, Aline; Makhalanyane, Thulani P.; Cowan, Don A.; Frey, Beat (Microbiology Society, 2021-04-13)

The warming-induced thawing of permafrost promotes microbial activity, often resulting in enhanced greenhouse gas emissions. The ability of permafrost microorganisms to survive the in situ sub-zero temperatures, their ...
