Cover Cropping Impacts Soil Microbial Communities and Functions in Mango Orchards

Agriculture, 2021
Soil microbes play critical roles in nutrient cycling, net primary production, food safety, and climate change in terrestrial ecosystems, yet their responses to cover cropping in agroforestry ecosystems remain unknown.

Impact of Arsenite on the Bacterial Community Structure and Diversity in Soil

Microbes and environments, 2016
The impact of arsenite (As[III]) on the bacterial community structure and diversity in soil was determined by incubating soil slurries with 50, 500, and 5,000 μM As(III). As(III) was oxidized to arsenate (As[V]), and the microbial contribution to As(III) oxidation was 70-100%.

Maize Endophytic Bacterial Diversity as Affected by Soil Cultivation History [PDF]

Frontiers in Microbiology, 2018
The bacterial endophytic communities residing within roots of maize (Zea mays L.) plants cultivated by a sustainable management in soils from the Quechua maize belt (Peruvian Andes) were examined using tags pyrosequencing spanning the V4 and V5 hypervariable regions of the 16S rRNA.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Responses of Soil Bacterial Diversity to Fertilization are Driven by Local Environmental Context Across China

Engineering, 2022
Soil microbial diversity is extremely vulnerable to fertilization, which is one of the main anthropogenic activities associated with global changes.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Manure amendment and the rhizosphere of Amaranthus hybridus soil bacterial communities in a semi-arid irrigated agroecosystem

Ecosistemas y Recursos Agropecuarios
Soil biodiversity is fundamental to nutrient cycling and ecosystem functioning in agroecosystems, yet the combined effects of organic amendments and weed rhizospheres on soil bacterial communities remain insufficiently explored in semi-arid irrigated ...

Effects of Urban–Rural Environmental Gradient on Soil Microbial Community in Rapidly Urbanizing Area

Ecosystem Health and Sustainability, 2023
Rapid urbanization considerably changes the urban–rural landscape, soil environment, and soil ecosystem functions. Within terrestrial ecosystems, microorganisms play key roles in soil ecosystem functions and are highly vulnerable to the effects of rapid ...

The persistence of bacterial diversity and ecosystem multifunctionality along a disturbance intensity gradient in karst soil

, 2020
Extensive, progressive rock emergence causes localized variations in soil biogeochemical and microbial properties that may influence the capacity for the regeneration of degraded karst ecosystems.

Effects of soil management on vegetation parameters, soil parameters, soil microbial diversity and soil functions in nine vineyards in Rhine-Hesse, Germany, studied from 2016-2017

, 2022
We investigated the effects of soil management on plant diversity, vegetation cover, soil parameters, bacterial and fungal diversity, and soil functions (soil respiration and decomposition of two different substrates) using a balanced experimental design
