Physiological and iTRAQ based proteomic analysis provided new insights into potassium deficiency stress response in alligator weed root. Alligator weed (Alternanthera philoxeroides) has a strong ability to adapt to potassium deficiency (LK) stress. Proteomic changes in response to this stress are largely unknown in alligator weed. In this study, we investigated physiological and molecular mechanisms under LK using isobaric tags for relative and absolute quantitation to characterize proteome-level changes in this plant...

Phosphatidylcholine (PC) is a major membrane phospholipid and a precursor for most signalling molecules. Understanding its synthesis is important for improving plant growth, nutritional value and resistance to stress. PC synthesis is complex, involving several interconnected pathways, one of which proceeds from serine-derived phosphoethanolamine (PEA) to form phosphocholine (PCho) through three sequential phospho-base methylations catalysed by phosphoethanolamine N-methyltransferases (PEAMTs). The contribution of this pathway to the production of PC and plant growth has been a matter of some debate...

BACKGROUND: Knowledge on the nutritional ecology of predatory coccinellids is important to selection of efficient biocontrol agents. We examined five species common to pistachio orchards and nutritional indices when fed on the key psylla pest of the system, Agonoscena pistaciae, in contrast to an alternative prey common on herbaceous plants in orchards, Aphis gossypii. RESULTS: Feeding studies revealed that Oenopia conglobata contaminata and Adalia bipunctata may be more efficient as biocontrol agents for A...

Microbes are known to influence insect-plant interactions; however, it is unclear if host-plant diet influences the regulation of nutritional insect symbioses. The pea aphid, Acyrthosiphon pisum , requires its nutritional endosymbiont, Buchnera , for the production of essential amino acids. We hypothesize that key aphid genes that regulate the nutritional symbioses respond to host-plant diet when aphids feed on a specialized (alfalfa) compared to a universal host-plant diet (fava), which vary in amino acid profiles...

This study aimed to assess the association of habitually low dietary calcium intake with blood pressure or hypertensive risk using data from the China Health and Nutrition Survey (CHNS) in 2009. We included 6298 participants (2890 men and 3408 women) aged 18 years or older in this analysis. Food intakes were measured by 3-day 24-h individual recalls combined with a weighing and measuring of household food inventory. The participants were divided into normotensive, pre-hypertensive and hypertensive groups according to their mean blood pressure of three repeated measurements...

Low soil temperature in spring is a major constraint for the cultivation of tropical and subtropical crops in temperate climates, associated with inhibition of root growth and activity, affecting early growth and frequently plant performance and final yield. This study was initiated to investigate the physiological base of cold-protective effects induced by supplementation with silicon (Si), widely recommended as a stress-protective mineral nutrient. Maize was used as a cold-sensitive model plant, exposed to chilling stress and low root-zone temperature (RZT) during early growth in a lab to field approach...

Alpha-linolenic acid (ALA) deficiency and a skewed n6:n3 fatty acid ratio in the diet is a major explanation for the prevalence of cardiovascular diseases and inflammatory/autoimmune diseases. There is mounting evidence of the health benefits associated with omega-3 long chain polyunsaturated fatty acids (LC PUFA's). Although present in abundance in fish, a number of factors limit our consumption of fish based omega-3 PUFA's. To name a few, overexploitation of wild fish stocks has reduced their sustainability due to increased demand of aquaculture for fish oil and meal; the pollution of marine food webs has raised concerns over the ingestion of toxic substances such as heavy metals and dioxins; vegetarians do not consider fish-based sources for supplemental nutrition...

Rice is an important cereal in the world. The study of the genetic basis of important agronomic traits in rice landraces and identification of genes will facilitate the breed improvement. Gelatinization temperature (GT), gel consistency (GC) and pericarp color (PC) are important indices of rice cooking and eating quality evaluation and potential nutritional importance, which attract wide attentions in the application of genetic and breeding. To dissect the genetic basis of GT, GC and PC, a total of 419 rice landraces core germplasm collections consisting of 330 indica lines, 78 japonica lines and 11 uncertain varieties were planted, collected, then GT, GC, PC were measured for two years, and sequenced using specific-locus amplified fragment sequencing (SLAF-seq) technology...

The microbiome is essential for extraction of energy and nutrition from plant-based diets and may have facilitated primate adaptation to new dietary niches in response to rapid environmental shifts. Here we use 16S rRNA sequencing to characterize the microbiota of wild western lowland gorillas and sympatric central chimpanzees and demonstrate compositional divergence between the microbiotas of gorillas, chimpanzees, Old World monkeys, and modern humans. We show that gorilla and chimpanzee microbiomes fluctuate with seasonal rainfall patterns and frugivory...

Phytomining techniques based on metal-hyperaccumulating plants can be implemented in serpentine quarry wastes for Ni recovery. However, strategies must be developed to overcome the unfavourable plant growth conditions that these substrates present and to optimize Ni yields. In this study, the Ni hyperaccumulators Alyssum serpyllifolium, Alyssum inflatum, and Alyssum bracteatum were evaluated for their Ni phytoextraction efficiency from quarry tailings. Effects of two organic amendments, composted municipal sewage sludge and cow manure, on plant growth and physiological status and Ni removal were determined...

Based on the forecasted warming scenarios by IPCC, we studied the impacts of warming (increased by 2.0 and 3.5 ℃) on seed reproduction of two lakeside dominant species (Schoeno-plectus tabernaemontani and Sparganium stoloniferum) in a typical plateau wetland (Napahai) in Northwestern Yunnan, by using "open-top chamber" technique. The results showed that warming had significant effects on the seed setting rate of both species, though with interspecific variation. The seed setting rate of S. tabernaemontani was significantly increased under two warming treatments, while that of S...

Evolutionary morphological and physiological differences between browsers and grazers contribute to species-specific digestion efficiency of food resources. Rumen microbial community structure of browsers is supposedly adapted to characteristic nutrient composition of the diet source. If this assumption is correct, domesticated ruminants, or grazers, are poor model animals for assessing the nutritional value of food consumed by browsing game species. In this study, typical spring and summer foods of the European moose ( Alces alces ) were combined with rumen fluid collected from both dairy cows ( Bos taurus ) and from moose, with the aim of comparing fermentation efficiency and microbial community composition...

Antioxidants have some health benefit, but up to now there was less attention paid to the antioxidant properties of dietary fibre. The antioxidant effect of dietary fibre is based on the polyphenol compounds bound to polysaccharide complexes, which are released in the gut and functioning as antioxidants. Another type of antioxidant, calcium fructoborate was also isolated from plant cell wall. It has a marked antioxidant capacity, however, its active component is not a polyphenol, but the boron. There are lots of food plants which have relatively high antioxidant dietary fibre content, thus they support the antioxidant defence of the gastrointestinal tract, and consequently the whole body...

Intercropping is a vital technology in resource-limited agricultural systems with low inputs. Peanut/maize intercropping enhances iron (Fe) nutrition in calcareous soil. In this study, the transcriptome of peanut and maize roots was analyzed by suppression subtractive hybridization (SSH) and microarray analysis separately. We constructed four SSH libraries using the cDNA of peanut roots based on two cropping patterns: monocropping and intercropping, and two growth stages: vegetative stage and reproductive stage...

Recent studies show that high-technology rare earth elements (REEs) of anthropogenic origin occur in the environment including in aquatic systems, suggesting REEs are contaminants of emerging concern. However, compared to organic contaminants, there is a lack of comprehensive reviews on the anthropogenic sources, environmental behaviour, and public and ecological health risks of REEs. The current review aims to: (1) identify anthropogenic sources, transfer mechanisms, and environmental behaviour of REEs; (2) highlight the human and ecological health risks of REEs and propose mitigation measures; and (3) identify knowledge gaps and future research directions...
