Carbon partitioning in nitrogen-fixing root nodules
Stickstoff-fixierende Wurzelnknöllchen repräsentieren starke Kohlenstoff- sinks". Die Zucker- verteilung wurde in verschiedenen symbiotischen Systemen untersucht, nämlich in einer Leguminose, Medicago truncatula, und zweier Aktinorhizapflanzen, Casuarina glauca und Datisca glomerata. Die …

ADVANCED HIGH STRENGTH STEEL THROUGH PARAEQUILIBRIUM CARBON PARTITIONING AND AUSTENITE STABILIZATION
… role in the retained austenite contents at carbon partitioning temperatures above 450¿¿C. A thermodynamic model predicted the retained austenite contents in steels with different chemical compositions and heat treatment schedules. The microstructure and mechanical behavior of two …

Comparative analysis of stem carbon partitioning and development in Andropogoneae bioenergy grasses
Plants fix carbon during photosynthetic reactions but how this carbon is distributed and stored throughout the plant greatly depends on the species. While cellulose and lignin are the more stable forms, the plant only needs to produce enough of it to allow for basic cell wall function. Starch is …

Underlining the potential drivers of carbon allocation in Kernza® crops
… investigates the primary factors influencing carbon allocation in Thinopyrum intermedium (Kernza) during its first growth year at the PERENNIAL experimental site in Alnarp, Sweden. Focusing on the distribution of aboveground and belowground biomass and the role of soil properties, this work …

Effects of CO₂ enrichment and potassium supply on growth and inorganic nutrition of chrysanthemum (Dendranthema grandiflora Tzvelev)
… processes, including mineral relations and carbon partitioning. Leaf abnormalities sometimes develop under long-term CO₂ enrichment, and previous research has correlated them with altered nutrient requirements and distribution. To explore the roles of CO₂ enrichment on the development of …

Regulation of reserve carbohydrates in hull-less barley grain
… this project provide fundamental knowledge about carbon partitioning in grain across development and suggest that small changes in polysaccharide synthesis and deposition can have significant effects on other metabolic processes important for correct grain development. While decreasing the amount …

Nitrogen and carbon balance of lactating Holstein cows during early and midlactation
… 2 factorial design to evaluate nitrogen (N) and carbon (C) partitioning to milk, urine, feces, and body tissue during early and midlactation. Diets containing 16% CP were formulated with 30 or 39% rumen undegradable protein (RUP) obtained by substituting blood meal (EM) for soybean meal (SBM). …

Development of Methods to Aid in Flotation Circuit Evaluations and Drip Pan Design
… diverged from expected trends with respect to carbon recovery and yield. Other work performed includes the development of a new carbon partitioning test, which uses a blender to provide a high shear environment and uses oil to partition the slurry into a carbon rich oil phase and an ash rich …

Patterns of carbon allocation, storage and remobilization in a common resprouting savanna species - Acacia karoo
… a comprehensive understanding of the patterns of carbon partitioning, storage and remobilization in Acacia karroo during the juvenile life history stage. Tuber total nonstructural carbohydrate (TNC) concentrations and δ¹³C values were determined in plants from two different stages in the juvenile …

The Synthetic Biology of N2-Fixing Cyanobacteria for Photosynthetic Terpenoid Production
… and mineralized water to energy-dense carbon molecules, as well as fix atmospheric nitrogen gas into ammonia for metabolism. Engineered cyanobacteria with re-wired metabolic pathways have recently been designed through synthetic biology, and they possess the ability to synthesize new …

Carbon-13 metabolic flux analysis of soybean central carbon metabolism: response to temperature and genotype effects
… unknown;Metabolic flux analysis (MFA) quantifies carbon flow in a biological system, which is an important characteristic reflective of the system physiology. The application of MFA to study complex plant metabolic networks has however been recent. Towards this goal, MFA using carbon labeling …

Unraveling the gene regulators and molecular mechanisms underlying the elevated CO2 response in C3 plants
Rising atmospheric carbon dioxide ([CO2]) concentrations, a major driver of climate change, also present a unique opportunity to enhance crop productivity, particularly in C3 plants. However, the extent of this CO2 fertilization effect is modulated by complex interactions with nutrient …

Photosynthesis and transpiration in a dry-land Pinus radiata forest
… explain a seasonal pattern in stable carbon isotope composition (δ¹³C) measured within annual rings of P. radiata from two sites which differed markedly in annual water balance. Over two growing seasons there was good agreement between mean canopy-level cᵢ derived from the tree-ring …

Lumped approach for sorption of organic contaminant mixtures to simulated aquifer sorbents
… aquifer sorbents with fractions of organic carbon (foc) ranging from 0.005 to 0.221 % were evaluated. The lumped approach consists of grouping one or more components in mixtures of NOCs into a fewer number of pseudocompounds that exhibit similar behavior with respect to a process being …

Heat transfer, evaporation and carbon dioxide transfer in soil
… energy balance. Soil water evaporation and soil carbon dioxide (CO2) fluxes both involve soil gas transport processes and properties, and both impact the soil environment and physical, chemical, and biological processes occurring in the soil. Accurate and dynamic measurements of soil water …

Carbon and Water Relations in Pinus Taeda: Bridging the Gap across Plant Physiology, Genomics, and Global Climate Change
… Specifically, it focused on processes affecting carbon and water exchange in forest trees because (1) trees are long-lived species that might face repeated environmental challenges; (2) relatively little information exists about the genes and the molecular mechanisms regulating structural and …
