Summary: The application of pulp and paper mill sludge to agricultural soils is a common strategy to improve soil properties and promote plant growth. This study evaluated the effects of sodium lignosulfonate (sLS) on cucumber plants grown under sufficient nutrient supply or soil nutrient deficit. The results showed that sLS reduced respiratory carbon losses and cell membrane permeability in cucumber leaves under nutrient deficit. It also helped to reduce the toxic levels of leaf manganese and iron.

Summary: Light-enhanced respiration (LER) occurs in both eukaryotic algae and photosynthetic prokaryote cyanobacteria, with similar physiological characteristics. However, LER in cyanobacteria is uncoupled from photosynthetic electron transport. It is primarily driven by substrates produced during photosynthetic CO2 assimilation and has significant physiological implications.

Summary: The isotopic composition of dissolved oxygen can be used as a tracer for respiration and transport in the subsurface ocean. However, uncertainties in transport parameters and isotopic fractionation factors limit its effectiveness. In this study, new data and a model were used to investigate the oxygen isotopologues in the subsurface Pacific. The results suggest that the traditional isotopic fingerprints associated with oxygen consumption in the Pacific Ocean may need to be reexamined.

Summary: The study found that anoxia-reoxygenation and cadmium have different effects on H2O2 emission in fish liver mitochondria, depending on the substrate used, leading to different response patterns. Additionally, anoxia-reoxygenation inhibits mitochondrial respiration in a substrate-dependent manner.

Summary: As global climate warms, increasing leaf temperatures have a significant impact on tree physiology and the interaction between leaf and air temperatures in forests. By warming leaves in two mature evergreen forests, researchers found that higher leaf temperatures lead to reduced stomatal conductance and net photosynthesis, potentially weakening the land carbon sink in tropical and temperate forests.

Summary: Dissolved oxygen (DO) is crucial for crab growth and is influenced by complex interactions between organism communities and meteorological factors. A dynamic model based on the diffusion theory can evaluate the effects of various environmental factors on DO dynamics and simulate DO content at different depths.

Summary: This study investigates the effects of dietary and genetic iron overload on mitochondrial function, revealing that iron accumulation promotes ROS production and impairs mitochondrial respiratory capacity. Differences in response to iron overload were observed in wildtype and genetic hemochromatosis model mice, suggesting the potential for iron reduction therapy to improve mitochondrial function.

Summary: The study found that the growth of Microcystis aeruginosa, a bloom-forming cyanobacterium, was initially inhibited by perfluorooctanoic acid (PFOA). However, the inhibition gradually decreased and stabilized over time. The self-adaptive mechanisms of the microalgae to PFOA exposure included antioxidant pathways, energy transfer and distribution of photosystems, and repair of specific complexes.

Summary: Heat stress affects crop productivity through impaired carbon metabolism and reproductive development. Understanding the integration of these processes and their contribution to yield maintenance is crucial for developing climate-resilient crops. Recent studies on source-sink dynamics, non-foliar photosynthesis, and net carbon gain provide key insights into improving reproductive development and crop productivity under heat stress.

Summary: The study examined the relationship among dietary methionine pattern, methionine metabolism, and antioxidant reactions in lambs to provide theoretical basis for amino acid nutrition and healthy feeding. Methionine restriction can alter the content of methionine and its metabolites, affecting the redox state by activating the Nrf(2) signaling pathway. Liver tissue adapts to oxidative environment by upregulating expression of antioxidant enzymes like GSH-Px and SOD, with a lag effect in metabolic recovery after methionine supplementation.

Summary: Seed size is an important trait for seed quality, reflecting the quantity of reserve material available for post-germinative processes. This study examined seed size and composition in different accessions of Medicago truncatula and found that N content increased and H content decreased with seed size. Metabolomic analysis showed that seed size correlated with free amino acid and hexoses content, and anticorrelated with amino acid degradation products, disaccharides, malic acid, and free fatty acids. The results suggest that seed size is determined by metabolic balance and may be influenced by phloem source metabolite delivery during seed development.

Summary: Phloem sap transport plays a crucial role in plant nutrition and development by redistributing nutrients, metabolites, and signaling molecules. However, its biochemical composition is not well-studied due to the difficulty in sampling and analyzing phloem sap. Recent metabolomics studies using liquid or gas chromatography coupled with mass spectrometry have provided insights into the phloem sap metabolome and its physiological implications. These studies show that phloem sap contains not only sugars and amino acids but also diverse metabolic pathways. They also suggest that metabolic exchange between source and sink organs is a common phenomenon, contributing to whole-plant metabolic cycles and shoot-root coordination of growth and development.
