Metabologenomic Hallmark‐Based Discovery of Bacterial Thioamides as a New Lead against Drug‐Resistant Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
A targeted metabologenomic strategy integrating genomic and metabolomic hallmarks enabled the discovery of two new thioamides, thiogochangamides A and B, from bacteria. Their absolute configurations, previously unresolved within the thioviridamide family, were fully assigned through various chemical derivatizations and computational analysis ...

Effects of biochar and Fe-modified biochar on acid buffering capacity and organic carbon fractions of lateritic red soil

open access: yesHuanan Nongye Daxue xuebao
ObjectiveLateritic red soil is a kind of acidic soil that covers a considerable proportion of the land in south China. Continuous soil acidification affects its physical and chemical property as well as biological characteristic, which is adverse to the ...

HYDROGEL AND ORGANIC CARBON SOIL

open access: yes, 2022
All over the world, including around the Aral region, the problem of strengthening mobile sands from wind erosion and preventing their rise into the atmosphere by creating a strong surface crust is urgent. One of the important promising directions in this area is the use of cheap, easily accessible local raw materials in mobile soil and sand ...

Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

open access: yesAdvanced Science, EarlyView.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

Carbon sequestration potential of reclaimed desert soils in Egypt [PDF]

open access: yes, 2009
The objective of this study was to investigate the carbon storage potential of reclaimed soils under organic management. Agricultural soils are often mentioned as a potential carbon sink. However, until now the UNFCCC (United Nations Framework Convention

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

open access: yesAdvanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

open access: yesAdvanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...

Empirical Analysis of Land-use Change and Soil Carbon Sequestration Cost in China [PDF]

open access: yes
This project examines the driving forces behind the land-use change and evaluates the effects of land-use transition on soil organic carbon density and sequestration cost in China. It contributes to the literature in three aspects.

The Maize ZmbHLH118 Transcription Factor Regulates Vacuolar Nitrate Loading by the NO3− Transporter ZmCLCa

open access: yesAdvanced Science, EarlyView.
In maize, the bHLH transcription factor ZmbHLH118 directly binds to the promoter of ZmCLCa and inhibits its expression. Tonoplast‐localized ZmCLCa mediates NO3− influx into the vacuole to regulate intracellular NO3− homeostasis, modulating nitrate uptake and metabolism, plant growth, and grain yield.

Estimating the Economic Value of Temporary and Permanent Carbon Sequestration Activities on Agricultural Land [PDF]

open access: yes
This paper estimates the value of carbon from soil sequestration and emission reductions from setting aside highly erodible land. Increases in soil carbon are estimated using the Intergovernmental Panel on Climate Change soil organic carbon inventory ...
