Postgerminative growth and lipid catabolism in oilseeds lacking the glyoxylate cycle [PDF]

, 2000
The glyoxylate cycle is regarded as essential for postgerminative growth and seedling establishment in oilseed plants. We have identified two allelic Arabidopsis mutants, icl-1 and icl-2, which lack the glyoxylate cycle because of the absence of the key ...

National forest carbon harvesting and allocation dataset for the period 2003 to 2018 [PDF]

Earth System Science Data
Forest harvesting is one of the anthropogenic activities that most significantly affect the carbon budget of forests. However, the absence of explicit spatial information on harvested carbon poses a huge challenge in assessing forest-harvesting impacts ...

Rapid turnover of hyphae of mycorrhizal fungi determined by AMS microanalysis of C-14 [PDF]

, 2003
Processes in the soil remain among the least well-characterized components of the carbon cycle. Arbuscular mycorrhizal (AM) fungi are ubiquitous root symbionts in many terrestrial ecosystems and account for a large fraction of photosynthate in a wide ...

Integrated modeling of blue and green water evolution in a headwater region of Chaohu Lake: Impacts of climate and surface environmental factors

Ecological Indicators
Understanding the dynamic changes of blue water (BW, surface and groundwater) and green water (GW, soil-stored rainfall used by plants via evapotranspiration) is essential for assessing water resource sustainability.

Holocene carbon-cycle dynamics based on CO2 trapped in ice at Taylor Dome, Antarctica [PDF]

, 1999
A high-resolution ice-core record of atmospheric CO2 concentration over the Holocene epoch shows that the global carbon cycle has not been in steady state during the past 11,000 years.

Variabilities of dissolved inorganic carbon along chain-shaped karst river-reservoir continuum: The control of cascade damming

Journal of Hydrology: Regional Studies
Study Region: The natural river, reservoir profiles, and inflow/outflow waters of ten cascade reservoirs along the Xijiang River in the subtropical karst region of southern China were studied.

Toarcian oceanic anoxic event: An assessment of global causes using belemnite C isotope records [PDF]

, 2005
Two hypotheses have been proposed to explain simultaneous large negative excursions (up to 7% PeeDee belemnite) in bulk carbonate (delta(13)C(carb)) and organic carbon isotope records (delta(13)C(org)) from black shales marking the Toarcian oceanic ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Integrated geochemical and geophysical assessment for monitoring soil stabilization with waste oyster shells

Scientific Reports
We assessed the field-scale stabilization efficiency of lead (Pb) and copper (Cu) in contaminated soils using powdered (WOS-P) and granular (WOS-G) waste oyster shell (WOS) amendments.
