Proteome-Wide Response of Dormant Caryopses of the Weed, , After Colonization by a Seed-Decay Isolate of .

Promoting seed decay is an ecological approach to reducing weed persistence in the soil seedbank. Previous work demonstrated that F.a.

People with chronic ankle instability benefit from brace application in highly dynamic change of direction movements.

Background: The application of ankle braces is an effective method for the prevention of recurrent ankle sprains. It has been proposed that the reduction of injury rates is based on the mechanical stiffness of the brace and on beneficial effects on proprioception and neuromuscular activation. Yet, how the neuromuscular system responds to the application of various types of ankle braces during highly dynamic injury-relevant movements is not well understood.

Chronic Sublethal Aluminum Exposure and Caryopsis Colonization Influence Gene Expression of F.a.1.

F.a.1 is a novel strain of a fungal plant pathogen capable of preferentially decaying wild oat () caryopses compared with those of wheat ().

Physical Mapping of Peroxidase Genes and Development of Functional Markers for on Bread Wheat Chromosome 7D.

Peroxidase (POD) activity in wheat ( L.) grain influences natural carotenoid pigment content and is associated with the color of flour, and processing and product quality. Here, we report the molecular characterization and physical mapping of POD genes in bread wheat.

Ankle Joint Control in People with Chronic Ankle Instability During Run-and-cut Movements.

Despite a considerable amount of research, the deficits causing recurrent sprains in people with chronic ankle instability are still unclear. Changes in frontal plane kinematics and decreased peroneal activation have been proposed as potential underlying mechanisms, but whether people with ankle instability show deficits in control of injury-relevant movements is not well understood. Therefore, the purpose of the present study was to analyse ankle joint kinematics and kinetics as well as neuromuscular activation during dynamic change-of-direction movements.

Defense Enzyme Responses in Dormant Wild Oat and Wheat Caryopses Challenged with a Seed Decay Pathogen.

Seeds have well-established passive physical and chemical defense mechanisms that protect their food reserves from decay-inducing organisms and herbivores. However, there are few studies evaluating potential biochemical defenses of dormant seeds against pathogens. Caryopsis decay by the pathogenic strain .

Preparation time influences ankle and knee joint control during dynamic change of direction movements.

The influence of preparation time on ankle joint biomechanics during highly dynamic movements is largely unknown. The aim of this study was to evaluate the impact of limited preparation time on ankle joint loading during highly dynamic run-and-cut movements. Thirteen male basketball players performed 45°-sidestep-cutting and 180°-turning manoeuvres in reaction to light signals which appeared during the approach run.

Repeatability of Mice Consumption Discrimination of Wheat (Triticum aestivum L.) Varieties across Field Experiments and Mouse Cohorts.

Unlabelled: Whole grain wheat (Triticum aestivum L.) foods can provide critical nutrients for health and nutrition in the human diet. Potential flavor differences among varieties can be examined using consumption discrimination of the house mouse (Mus musculus L.

Polyphenol oxidase as a biochemical seed defense mechanism.

Seed dormancy and resistance to decay are fundamental survival strategies, which allow a population of seeds to germinate over long periods of time. Seeds have physical, chemical, and biological defense mechanisms that protect their food reserves from decay-inducing organisms and herbivores. Here, we hypothesize that seeds also possess enzyme-based biochemical defenses, based on induction of the plant defense enzyme, polyphenol oxidase (PPO), when wild oat (Avena fatua L.

The house mouse (Mus musculus L.) exerts strong differential grain consumption preferences among hard red and white spring wheat (Triticum aestivum L.) varieties in a single-elimination tournament design.

Wheat (Triticum aestivum L.) plays a central role in the health and nutrition of humans. Yet, little is known about possible flavor differences among different varieties.

Effect of processing on phenolic composition of dough and bread fractions made from refined and whole wheat flour of three wheat varieties.

This study investigated the effect of breadmaking on the assay of phenolic acids from flour, dough, and bread fractions of three whole and refined wheat varieties. Comparison of the efficacy of two commonly used methods for hydrolysis and extraction of phenoilc acids showed that yields of total phenolic acids (TPA) were 5-17% higher among all varieties and flour types when samples were directly hydrolyzed in the presence of ascorbate and EDTA as compared to the method separating free, soluble conjugates and bound, insoluble phenolic acids. Ferulic acid (FA) was the predominant phenolic acid, accounting for means of 59 and 81% of TPA among all refined and whole wheat fractions, respectively.

Optimizing experimental design using the house mouse (Mus musculus L.) as a model for determining grain feeding preferences.

There is little research evaluating flavor preferences among wheat varieties. We previously demonstrated that mice exert very strong preferences when given binary mixtures of wheat varieties. We plan to utilize mice to identify wheat genes associated with flavor, and then relate this back to human preferences.

Phytochemical composition, anti-inflammatory, and antiproliferative activity of whole wheat flour.

Whole wheat flour from five wheat cultivars was evaluated for phenolic, carotenoid, and tocopherol compositions as well as anti-inflammatory and antiproliferative activities against HT-29 cells. The total ferulic acid content ranged from 452 to 731 μg/g among the five cultivars and was primarily present in the insoluble-bound form. Lutein was the only carotenoid detected and ranged from 1.

Activation of polyphenol oxidase in dormant wild oat caryopses by a seed-decay isolate of Fusarium avenaceum.

Incubation of dormant wild oat (Avena fatua L., isoline M73) caryopses for 1-3 days with Fusarium avenaceum seed-decay isolate F.a.

Delineating the role of polyphenol oxidase in the darkening of alkaline wheat noodles.

This study evaluated the effects of inhibitors on polyphenol oxidase (PPO) activity, the effect of the PPO inhibitor tropolone on noodle darkening, and the correlation of PPO activity with darkening of alkaline noodles. The PPO inhibitors tropolone and salicylhydroxamic acid (each at 1 microM) reduced kernel PPO activity by approximately 50% in three hexaploid wheat cultivars but did not inhibit PPO activity in the two very low PPO cultivars, durum Langdon, and the synthetic hexaploid-derived ID580. Tropolone (100 microg/g flour) inhibited alkaline noodle darkening (deltaL*) by 13-25% in the low PPO wheat cultivar, ID377s, and by 39-54% in the high PPO wheat cultivar, Klasic.
