Gas exchanges in peach palms as a function of the spad chlorophyll meter readings

Revista Brasileira de Fruticultura, 2011
The close relationship between the chlorophyll-meters readings and the total chlorophyll and nitrogen contents in leaves, has allowed their evaluation both in annual and perennial species.

ANALYSIS OF THE TEMPERATURE DEPENDENCE OF CO2 ASSIMILATION RATE (STUDY CASE: GLYCINE MAXL. MERR)

Biotropia: The Southeast Asian Journal of Tropical Biology, 2011
The maximum rate of carboxylation (Kcmax) and maximum rate of regeneration of Ribulose bisphosphate (RuBP) (controlled by the rate of electron transport, Jmax) arc two processes governing the photosynthetic capacity of plants.

Critical Leaf Magnesium Thresholds and the Impact of Magnesium on Plant Growth and Photo-Oxidative Defense: A Systematic Review and Meta-Analysis From 70 Years of Research

Frontiers in Plant Science, 2019
Magnesium (Mg) deficiency in plants is a widespread problem affecting productivity and quality in agricultural systems and forestry. Although numerous studies addressed the effect of Mg deficiency on biomass and photosynthetic CO2 assimilation, a summary

PSI-mediated NADPH production and enzyme regulation are critical for carbon assimilation in pepper seedlings under cadmium stress

Horticultural Plant Journal
Photosynthetic CO2 assimilation forms the basis of crop growth and yield formation and is highly sensitive to soil cadmium (Cd) pollution. This study investigated the mechanisms behind Cd-induced inhibition of photosynthetic CO2 assimilation in pepper ...

Neutrophil‐Mimetic MRI Enables Ultra‐Early Detection of Vascular Inflammation After Stroke

Advanced Healthcare Materials, EarlyView.
In this study, we developed neutrophil‐mimetic MRI probes that detect ultra‐early neuroinflammation following ischemic stroke by targeting E‐selectin. Within seconds of their injection, these microparticles mimic initial leukocyte adhesion to the activated cerebral endothelium.

Developing a Functional Polyelectrolyte Hybrid Layer Scaffold Coating and Evaluation of Its Performance for Interaction With Neural Cells

Advanced Materials Interfaces, EarlyView.
Polyelectrolyte scaffold coatings modified with Cu and Fe3O4 nanoparticles regulate neural stem cell behavior in vitro. Increased Fe3O4 content enhances mitochondrial activity and neuronal differentiation, whereas higher Cu levels reduce cell viability.

Organization and regulation of cbb CO2 assimilation genes in autotrophic bacteria [PDF]

FEMS Microbiology Reviews, 2006
The Calvin-Benson-Bassham cycle constitutes the principal route of CO2 assimilation in aerobic chemoautotrophic and in anaerobic phototrophic purple bacteria. Most of the enzymes of the cycle are found to be encoded by cbb genes. Despite some conservation of the internal gene arrangement cbb gene clusters of the various organisms differ in size and ...

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Cross Kingdom Metabolic Engineering Paradigm Elevating Sustainable Protein Production

Advanced Science, EarlyView.
ABSTRACT Confronting the dual crisis of escalating global protein demand and unsustainable agriculture necessitates transformative solutions. Here, we pioneer evolutionary insights from maize nitrogen optimization via asparagine synthetase (ASNS) to rewire metabolism in Pichia pastoris.
