TL;DR: Results indicate that reduction in hypercholesterolemic atherosclerosis by Type II flaxseed is due to a decrease in serum TC and LDL-C, which is not due to alpha-linolenic acid.

TL;DR: A high-density single nucleotide polymorphism (SNP) Illumina Infinium array, containing 52,157 markers, was developed for the allotetraploid Brassica napus, a valuable tool for genetic fine mapping and genome-wide association studies in B. napus and its progenitor genomes.
Abstract: Key message TheBrassica napusIllumina array provides genome-wide markers linked to the available genome sequence, a significant tool for genetic analyses of the allotetraploidB. napusand its progenitor diploid genomes.

TL;DR: In this paper, a global radiocarbon data set suggests that human disturbance is also introducing aged carbon to rivers and to active carbon cycling and that most dissolved organic carbon in rivers originates from young carbon in soils and vegetation.

TL;DR: Changes in levels of sugar and starch indicated a more rapid disruption of carbohydrate utilization in comparison to photosynthetic rates in the chilling-sensitive line under short-term chilling shocks and suggested a greater degree of acclimation in the tolerant lines over longer periods of chilling.
Abstract: Antioxidant enzyme activities were determined at the first, third and fifth leaf stages of four inbred lines of maize (Zea mays L.) exhibiting differential sensitivity to chilling. Plants were exposed to a photoperiod of 16:8 L: D for one of three treatments: (a) control (25°C), (b) control treatment plus an exposure to a short-term chilling shock (11°C 1d prior to harvesting), and (c) long-term (11 °C constant) chilling exposure. Catalase (CAT; EC 1.11.1.6), ascorbate peroxidase (ASPX; EC 1.11.1.11), superoxide dismutase (SOD; EC 1.15.1.1), glutathione reductase (GR; EC 1.6.4.2), and monodehydroascorbate reductase (MDHAR; EC 1.6.5.4) activities were assessed. Reducing and non-reducing sugars and starch concentrations were determined as general metabolic indicators of stress. Reduced activities of CAT, ASPX, and MDHAR may contribute to limiting chilling tolerance at the early stages of development in maize. Changes in levels of sugar and starch indicated a more rapid disruption of carbohydrate utilization in comparison to photosynthetic rates in the chilling-sensitive line under short-term chilling shocks and suggested a greater degree of acclimation in the tolerant lines over longer periods of chilling.

Journal ArticleDOI
TL;DR: In this article, the authors developed a sensitive method to identify and quantify organic acids in soil extracts from the rhizosphere of quackgrass grown under greenhouse conditions, which involves ion-exchange chromatographic separation using step gradient, and quantification by UV absorption for aromatic acids and by conductivity for aliphatic acids.
Abstract: Low molecular-weight organic acids play a determinant role in nutrient cycling and plant growth in agricultural and forest ecosystems Our study was made to develop a sensitive method to identify and quantify organic acids in soil extracts from the rhizosphere of quackgrass grown under greenhouse conditions The procedure involves ion-exchange chromatographic separation using step gradient, and quantification by UV absorption for aromatic acids and by conductivity for aliphatic acids In a single chromatographic run, 14 aliphatic acids were separated in 55 min and 14 aromatic acids in 25 min The methods have high precision with relative standard deviations of peak areas ranging from 150 to 799% for aliphatic acids and from 065 to 637% for aromatic acids The method for aliphatic acids is recommended for mono- or dicarboxylic acid analysis, whereas the method for aromatic acids constitutes a major improvement over previous procedures We identified 13 organic acids in the quackgrass rhizosphere and 18 organic acids in soil containing decomposing residues of this plant The largest concentrations were found in soils containing quackgrass residues Aliphatic acid concentrations were generally larger than those of aromatic acids Formic and acetic acids dominated the aliphatic group, whereas benzoic and p -hydroxybenzoic acids were found in largest amounts among aromatic acids
